The "hamburger menu" is a popular menu control for modern mobile applications. We have NavigationPane whose layout looks similar to this "hamburger menu", but has several differences. So, this example demonstrates how to customize the current NavigationPane behavior to make it look like the mentioned menu for modern mobile applications.

Multiple selection using checkbox (web style)

December 31, 2000, 4:00 pm
$
0

From version 13.2, the GridView in the XtraGrid control provides a built-in checkbox column for multiple row selection.

This feature is demonstrated in the following example: How to use an unbound check box column to select grid rows. Additional information can be found in the following topic: Multiple Row Selection via Built-In Check Column


Projects attached to the current article target earlier versions of DevExpress controls, which did not provide the built-in checkbox column for multiple row selection.
These examples show how to manually add a check column to allow web-style multiple row selection. End-users can select/deselect rows, group rows or select/deselect all rows by clicking the column header. Changing a check box value does not initiate row editing. These examples are based on the A371 article.

I had the same problem as You Logic ! How select row (with checkbox) from code ?

Added By: (no info) at: 11/25/2013 2:23:24 PM    

While this is a very nice implementation there is a problem with the code. Because you have defined selection *in the CheckMarkSelection.cs" as an ArrayList it is next to impossible to get at any values contained within each of the actual selected rows from the grid. Let's say one needs to obtain two of the values within the row...one is a string and one is an integer...how do you get the values out? There are no extension methods associated with "selection" that would allow you to enumerate the data lets say using linq or even simply doing somethin like: DataRowView theRow = (DataRowView)this.selection.GetSelectedRow(i); What happens is there is a cast error that occurs due to the generic types within the ArrayList. Granted this is necessary as we have an unknown group of column objects and values. There needs to be a built in method to access the individual values in the selected rows from "selection". I have tried 12 different methods to extract them and still a Cast error occurs.

HI I need to merge Columns also. Not the header. I used following code change in the below code

public class TreeListHeaderMerger

       public TreeListHeaderMerger(TreeList treeList, TreeListColumn columnToMerge)

           this.columnToMerge = columnToMerge;
           columnToMerge.OptionsColumn.AllowMove = false;
           GetNextColumn().OptionsColumn.AllowMove = false;
           treeList.CustomDrawColumnHeader += treeList_CustomDrawColumnHeader;
           treeList.CustomDrawNodeCell += treeList_CustomDrawNodeCell;
       }

       void treeList_CustomDrawNodeCell(object sender, CustomDrawNodeCellEventArgs e)
       {

           TreeListColumn nextColumn = GetNextColumn();
           if (nextColumn == null) return;
           if (e.Column == nextColumn) { e.Handled = true; return; }
           if (e.Column != columnToMerge) return;
           Rectangle r = e.ObjectArgs.Bounds;
           r.Width = r.Width + nextColumn.VisibleWidth;
           e.ObjectArgs.Bounds = r;
       }

       TreeListColumn GetNextColumn()
       {
           if (columnToMerge.VisibleIndex == treeList.Columns.Count - 1) return null;
           return treeList.Columns[columnToMerge.VisibleIndex + 1];
       }

       void treeList_CustomDrawColumnHeader(object sender, CustomDrawColumnHeaderEventArgs e)
       {
           TreeListColumn nextColumn = GetNextColumn();
           if (nextColumn == null) return;
           if (e.Column == nextColumn) { e.Handled = true; return; }
           if (e.Column != columnToMerge) return;

           r.Width = r.Width + nextColumn.VisibleWidth;
           e.ObjectArgs.Bounds = r;
       }
   }

But I can't able to merge columns Its hiding second column value but not the border. Once I clicking the specific field I'm able to view the data also. Am I missing any thing?

The following example demonstrates how to get client data corresponding to a particular visual element using DashboardViewer's API.
In this example, the DashboardViewer.DashboardItemClick event is handled to obtain client data for the Card dashboard item and display this data in a Chart control. We obtain axis points placed on the "Sparkline" axis for the clicked card, determine corresponding actual/target values, and save these values to a data table. This table is used as a data source for the Chart control. 
Note that you can apply master filtering by year in the Pie dashboard item. The chart will display client data according to the selected year.

How to establish association from one class to many classes

$

For instance, you have a class for File. This class will be used in more than one BO. Each BO would then have a listview of Files that are attached to the particular class.
To accomplish this, you can create a super class, say DomainObjectBase and then establish a one-to-many relationship between the File class. After that you can derive your BOs from the DomainObjectBase class and they will automatically get the parent's relationships.

Question Comments
Added By: Martin D. at: 6/21/2014 11:01:22 AM    

Is it possible - to also associate with different representations of "File" ?
So that DomainObject1 -> get's a collection of GetCollection<MyFile>("files")
and domainObject2 -> Get's a collection of GetCollection<PngFile>("files") ?

Added By: Dennis (DevExpress Support) at: 6/23/2014 6:15:09 AM    

I see several possible solutions for this:

1. Use the current code as is, create File descendants and then customize the New Action depending on the selected type to allow creation only of required file types. See also the How to display details collections with descendant classes filtered by object type in a DetailView  example for some example code on creating descendants and presenting them in the UI (this is not exactly what you are looking for, but it demonstrates a part of the described solution).
2. Do not have a common association and rather implement specific associations for each object and file type.

How to add a custom summary item to the grid's footer menu

Sometimes it's necessary to specify a way of calculating summaries that is different from the default one. Assume you don't want to take into account cells with no data when calculating summaries. It's possible to accomplish this task using two events: use the GridView.CustomSummaryCalculate event to provide a custom summary and the GridView.PopupMenuShowingevent to add a corresponding item to the grid's footer menu.

Not a single code comment.. Nice..

Added By: Matteo Lazzari at: 6/5/2014 3:12:58 AM    

Why do you do:

foreach (DevExpress.Utils.Menu.DXMenuItem item in footerMenu.Items)
               item.Enabled = true;

I see this is necessary for enable the menu items... But I would like to maintain disabled the summarization items not available for a particular field type (for example, the sum for the strings). Is this possible?
Thank you.

Added By: Nikita (DevExpress Support) at: 6/6/2014 1:25:50 AM    

Hello,
Our grid inner logic disables all items in the summary popup menu when a custom summary is applied to the grid. We use this loop to overcome this behavior without creating a big hierarchy of derived controls. 
If you need to disable some items, you can create a structure that stores items that should be disabled not to enable these items in this loop. 
I hope this helps.

Added By: Matteo Lazzari at: 6/11/2014 6:23:13 AM    

Ok, thank you. Using a dictionary that stores the key "FieldName + the summary Caption" and the value of the enabled property I can maintain the original enabled property value, except for the "None" element that I test in this way:

If item.Tag.Equals(GridStringId.MenuFooterNone) Then ...

Now, I've got another issue. Since my grid is inside the XAF Framework the active summarization items are stored in the user model and when I load the grid they are already visible. But the CustomSummaryCalculate logic fails because the tag has not value.
What can I do?

Added By: Nikita (DevExpress Support) at: 6/12/2014 3:59:26 AM    

Hello,
Identification of a custom summary by tag is applicable for XAF, since it does not restore the SummaryItem.Tag property. If you have only one custom summary, you can simply remove a check of the CustomSummaryCalculate event handler. 
If you have a number of summaries, you need to save the currently applied summary name and restore it manually when necessary. 
I hope this helps.

Added By: Matteo Lazzari at: 11/19/2014 12:31:32 AM    

Thank you Nikita. How can I save the currently applied summary name and how to restore it?

Added By: Nikita (DevExpress Support) at: 11/19/2014 7:16:30 AM    

Hello,
 You can serialize the currently applied property in any manner that is convenient in the View.ModelSaved event handler and restore these settings in the View.ModelLoaded  event handler. 
I hope this helps.

How to manage users (register a new user, restore a password, etc.) from the logon form in ASP.NET

May 31, 2012, 9:14 am
$
0
0

Scenario
This example contains a reusable Security.Extensions module that provides a possible solution for the following scenarios:

Security - provide the capability to register a new user from the logon form
Security.Authentication - provide a "Forgot Password" feature

Refer to the following video to see the module features in action: http://www.screencast.com/t/h2goGEdZJc

Steps to implement

In order to use this module in your project, do the following:

1. Download and include the Security.Extensions module project into your XAF solution (as per MSDN) and rebuild it. This custom module contains Application Model settings (Model.DesignedDiffs.xafml) to layout custom Actions next to the logon form input fields (see the How to: Include an Action to a Detail View Layout  article for more details) as well as non-persistent data models for parameter screens (LogonActionParameters.cs) and finally a ViewController (ManageUsersOnLogonController.cs) for the logon DetailView that declares custom Actions and their behavior. The controller is registered via the XafApplication.CreateCustomLogonWindowControllers event in the ModuleBase descendant (Module.cs) along with other service logic.

2. Invoke the Module Designer for your platform-agnostic module and drag and drop the SecurityExtensionsModule from the Toolbox;

3. Add the following code into your platform-agnostic module class:

[C#]
staticYourPlatformAgnosticModuleName(){SecurityExtensionsModule.CreateSecuritySystemUser=Updater.CreateUser;}

where 'Updater.CreateUser' is your custom method that matches the following definition:

[C#]
publicdelegateIAuthenticationStandardUserCreateSecuritySystemUser(IObjectSpaceobjectSpace,stringuserName,stringemail,stringpassword,boolisAdministrator);

 

IMPORTANT NOTE
This module is currently ASP.NET only.

Added By: drew.. at: 3/11/2013 10:12:45 AM    

.. for the benefit of others, this reference to "module" in #1 above, means to drop the entire Security.Extensions folder from the demo into your current solution that you want to update with the basic feature. Then add a reference from your platform-agnostic module (PAM) to the added project, rebuild, THEN go into the module designer for the PAM and drag-n-drop your newly added security module into the required modules section. Then rebuild again.

Would you please submit a separate ticket and attach a screenshot of the desired UI, because possible solutions will vary a lot based on the exact logo placement?

This example demonstrates how to use the ShowCaret and HideCaret functions of the user32.dll with the TextEdit control and its descendants.

Question Comments
Added By: Dimitris Trivizakis at: 4/19/2016 4:46:14 AM    I'm using the exact same code for a ButtonEdit instance (which is a descendant) but i can't get the editor's cursor to blink when it is not focused.
Isn't that the purpose of  ShowCaret? Or maybe I'm missing something

How to copy a cell's value to other cells by dragging its right bottom edge

October 26, 2010, 2:49 am

This example demonstrates how to provide the capability to copy cell values like this is done in MS Excel. In this example, when a cell is selected, you can see a small black rectangle at the bottom. If you drag this rectangle and extend GridView's selection, all selected cells will have the same value as that of a source cell.

Question Comments
Added By: Alex Vignola at: 4/19/2016 7:25:12 AM    Hi, first i'd like to report an error in one of the version of your code, and also a little addition.

In the v2010 vol1.4 - v2011 vol1.4 sample... In the SelectedCellsBorderHelper class, in the GetCellRect function, GetGridCellInfo should receive column.AbsoluteIndex and not column.VisibleIndex

Also if you want to handle non editable columns, one would need to modify two things
[VB.NET]
PrivateSub CopyCellsValues()Dim value AsObject = View.GetRowCellValue(SourceGridCell.RowHandle, SourceGridCell.Column)Dim selectedCells() As GridCell = View.GetSelectedCells()ForEach cell As GridCell In selectedCellsIf cell.Column.OptionsColumn.AllowEdit AndAlsoNot cell.Column.OptionsColumn.ReadOnlyThen
                View.SetRowCellValue(cell.RowHandle, cell.Column, value)EndIfNext cellEndSub

[VB.NET]
PrivateFunction GetSelectionBounds() As RectangleDim width AsInteger = 0Dim height AsInteger = 0Dim rTop As Rectangle = Rectangle.EmptyDim shouldReturn AsBoolean = FalseDim view As GridView = TryCast(GridControl.FocusedView, GridView)Dim info As GridViewInfo = TryCast(view.GetViewInfo(), GridViewInfo)Dim gridCells() As GridCell = view.GetSelectedCells()If gridCells.Length = 0 Then
            shouldReturn = TrueReturn Rectangle.EmptyEndIfDim hb As Brush = Brushes.BlackDim visibleColl AsNew List(Of GridCellInfo)()ForEach row As GridRowInfo In info.RowsInfoDim coll As GridCellInfoCollection = (TryCast(row, GridDataRowInfo)).CellsForEach cell As GridCellInfo In coll
                visibleColl.Add(cell)Next cellNext rowDim collection AsNew List(Of GridCellInfo)()ForEach cell As GridCell In gridCellsForEach cellInfo As GridCellInfo In visibleCollIf cellInfo.RowInfo IsNot NothingAndAlso cellInfo.ColumnInfo IsNot NothingThenIf cell.RowHandle = cellInfo.RowHandle AndAlso cell.Column.Equals(cellInfo.Column) AndAlsoNot cell.Column.OptionsColumn.ReadOnlyAndAlso cell.Column.OptionsColumn.AllowEdit Then
                        collection.Add(cellInfo)EndIfEndIfNext cellInfoNext cellIf collection.Count = 0 Then
            shouldReturn = TrueReturn Rectangle.EmptyEndIf
        rTop = GetCellRect(view, collection(0).RowHandle, collection(0).Column)Dim rBottom As Rectangle = GetCellRect(view, collection(collection.Count - 1).RowHandle, collection(collection.Count - 1).Column)If rTop.Y > rBottom.Y Then
            height = rTop.Y - rBottom.BottomElse
            height = rBottom.Bottom - rTop.YEndIfIf rTop.X <= rBottom.X Then
            width = rBottom.Right - rTop.XElse
            width = rTop.X - rBottom.RightEndIfReturnNew Rectangle(rTop.X, rTop.Y, width, height)EndFunction

How to implement the Drag&Drop functionality for the CardView

We have created an example demonstrating how to implement the Drag&Drop functionality for the CardView.

This functionality is encapsulated in the CardDragDropManager class. So, all you need to do is to attach this behavior to the GridControl.

Question Comments
Added By: A Dev at: 10/24/2014 12:19:57 PM    

Where to find the DragDropManagerBase class?

Added By: Ivan (DevExpress Support) at: 10/24/2014 12:47:27 PM    

You can find this class in the C:\Program Files (x86)\<DevExpress folder>\Components\Sources\DevExpress.Xpf.Grid\DevExpress.Xpf.Grid.Extensions\DragDrop\DragDropManager\DragDropManagerBase.cs file. Note that this file will be installed regardless your subscription type. It's available for trial users as well.

GridView - How to correct the column layout if column widths are set in percentages and the grid is grouped

February 25, 2016, 7:48 am
$
0

This example illustrates the solution for the first issue described at ASPxGridView - Why column layout may become broken after user actions if certain column widths are set in percentages. 
The main idea is to determine the widest column and delete its width setting. As a result, the widest column will fill the space that appears after moving one of the columns to the Group panel. 
For this, we implemented the GridViewColumnHelper class and use Session  to preserve information about column width between requests to the server.

How to sort a ASPxPivotGrid by clicking on a field value

December 31, 2000, 4:00 pm

The PivotGrid allows sorting by any column. To do this, right click any field value and select an appropriate field to sort by it. Sometimes it is possible to sort by any column by simply clicking on it. This example shows how to implement this behavior. You should create a template for field values to place a hyperlink (or a button) rather than a plain text.

[C#]
ASPxPivotGrid1.FieldValueTemplate=newFieldValueTemplate(ASPxPivotGrid1);

The FieldValueTemplate class should implement the ITemplate interface. We've replaced standard contents of a field value in the InstantiateIn method.

[C#]
publicclassFieldValueTemplate:ITemplate{   publicFieldValueTemplate(ASPxPivotGridpivotGrid){       this.pivotGrid=pivotGrid;   }   ASPxPivotGridpivotGrid;   protectedASPxPivotGridPivotGrid{get{returnpivotGrid;}}   #regionITemplateMembers   publicvoidInstantiateIn(Controlcontainer){       PivotGridFieldValueTemplateContainerc=(PivotGridFieldValueTemplateContainer)container;       HyperLinklink=newHyperLink();       link.Text=(string)c.Text;       link.NavigateUrl="#";       link.Attributes["onclick"]=GetOnClickHandler(c);       c.Controls.Add(link);       boolisSortedByColumn=GetIsSortedByColumn(c);       if(isSortedByColumn){           c.Controls.Add(newLiteralControl("&nbsp;*"));       }   }   boolGetIsSortedByColumn(PivotGridFieldValueTemplateContainerc){       List<PivotGridFieldPair>sortedFields=PivotGrid.Data.VisualItems.GetSortedBySummaryFields(c.ValueItem.IsColumn,c.ValueItem.Index);       boolisSortedByColumn=sortedFields!=null&&sortedFields.Count> 0;       returnisSortedByColumn;   }   stringGetOnClickHandler(PivotGridFieldValueTemplateContainerc){       StringBuilderres=newStringBuilder();       res.Append(pivotGrid.ClientInstanceName).Append(".PerformCallback('SC|");       res.Append(GetFieldIndex(c)).Append("|")           .Append(c.ValueItem.IsColumn).Append("|")           .Append(c.ValueItem.VisibleIndex).Append("|")           .Append(c.ValueItem.DataIndex);       res.Append("');");       returnres.ToString();   }   intGetFieldIndex(PivotGridFieldValueTemplateContainerc){       returnc.ValueItem.Field!=null?c.ValueItem.Field.Index:-1;   }   #endregion}

The GetOnClickHandler method returns a javascript code that will perform a ASPxPivotGrid's callback passing all required parameters to the server. On the server side, you should handle the CustomCallback event handler and apply sorting to it.

[C#]
   protectedvoidASPxPivotGrid1_CustomCallback(objectsender,PivotGridCustomCallbackEventArgse){       string[]args=e.Parameters.Split('|');       if(args[0]=="SC")           HandleSortByColumnClick((ASPxPivotGrid)sender,args);   }   voidHandleSortByColumnClick(ASPxPivotGridpivotGrid,string[]args){       intfieldIndex=int.Parse(args[1]),           visibleIndex=int.Parse(args[3]),           dataIndex=int.Parse(args[4]);       boolisColumn=bool.Parse(args[2]);       PivotAreaarea=GetArea(isColumn),           crossArea=GetCrossArea(isColumn);       PivotGridFielddataField;       List<PivotGridField>fields;       List<object>values;       GetFieldsAndValues(pivotGrid,fieldIndex,visibleIndex,dataIndex,area,           outdataField,outfields,outvalues);              SetSortByColumn(pivotGrid,crossArea,dataField,fields,values);   }

Sorting can be set by filling the SortBySummaryInfo structure. The BeginUpdate/EndUpdate method calls are necessary to prevent multiple data recalculations.

[C#]
   voidSetSortByColumn(ASPxPivotGridpivotGrid,PivotAreacrossArea,PivotGridFielddataField,List<PivotGridField>fields,List<object>values){       pivotGrid.BeginUpdate();       List<PivotGridField>crossFields=pivotGrid.GetFieldsByArea(crossArea);       for(inti= 0;i<crossFields.Count;i++){           crossFields[i].SortBySummaryInfo.Field=dataField;           crossFields[i].SortBySummaryInfo.Conditions.Clear();           for(intj= 0;j<values.Count;j++){               crossFields[i].SortBySummaryInfo.Conditions.Add(                   newPivotGridFieldSortCondition(fields[j],values[j]));           }       }       pivotGrid.EndUpdate();   }
