How to create a PropertyEditor based on the XtraRichEdit control

December 31, 2000, 4:00 pm
$
0
0

Take special note that this editor is intended to be used for a simple and most common scenario when only one text property in a Detail View is edited with the help of the XtraRichEdit control (RichEditControl). Other scenarios are not supported in this example and are required to be implemented manually. For example, if there are more than one property, edited with this editor in a Detail View, then there may be problems with merging in ribbons. See the B142856 issue for more detailed information.

After copying the necessary files to my project, i ran into an error in MergeRibbonDetailViewController. I changed the code slightly (in the test):

        private void Frame_TemplateChanged(object sender, EventArgs e) {
            UnMergeRibbon();
            mainRibbonControl = null;
            IClassicToRibbonTransformerHolder form = Frame.Template as IClassicToRibbonTransformerHolder;
            if (form != null && form.RibbonTransformer != null) {
                form.RibbonTransformer.Transformed += RibbonTransformer_Transformed;
            }

How to sort Appointments with the same time interval

This example illustrates how to sort Appointments with the same time interval. This can be useful if you wish to sort all-day appointments (or daily appointments with the same Start and End values) by your custom rule.

This functionality may be introduced by implementing a custom DevExpress.XtraScheduler.Services.Internal.IExternalAppointmentCompareService service.

Can I also get an example how to implement this in ASP.NET?

Added By: Stijn Vandenbroucke at: 6/15/2015 12:21:40 PM    

Is there any possibility to perform this on all appointments? And not only on those with 'same time interval'?

Best regards,
Stijn.

Added By: Oleg (DevExpress Support) at: 6/16/2015 2:13:33 AM    

Hello Stijn,
By default, SchedulerControl sorts appointments by their time interval (the start and end dates). Only for appointments with the same start and end time, you can specify a custom sort algorithm. There is no capability to customize the sort order for appointments in case at least one of these dates is different. We have plans to provide more extended capabilities to customize the appointment layout (including the location of appointments within a time cell) in the scope of the following thread:
Provide a way to define a custom appointment layout
However, we have not yet decided when it will be implemented. Thus, at present we can't suggest any solution to customize the appointment sort order in case appointments have different start or end dates.

How to update external references in the loaded workbook.

November 21, 2014, 5:55 am
$
0
0
When the SpreadsheetControl loads a workbook containing external references, they are added to the IWorkbook.ExternalWorkbooks collection. However, the external references, created in this manner, are not "live". The references contain cached data and the SpreadsheetControl cannot update them.
To make a reference updateable, it should be replaced with a reference to a workbook instance.
Note that the use of the Workbook class instance in production code requires a license to the DevExpress Document Server or the DevExpress Universal Subscription.

This example demonstrates how to accomplish this. To create a workbook instance, load a workbook file into an instance of the Workbook class (or into another SpreadsheetControl instance).
Subsequently the ExternalWorkbookCollection.Replace method is used to replace the cached reference with a live external reference.
Note that a workbook name in the external reference should be identical to the WorkbookSaveOptions.CurrentFileName property of the referenced workbook instance when the workbook is added to the ExternalWorkbookCollection. That is, if the workbook instance is created by loading a file using a full path, the reference should contain the full path, e.g. 'C:\Temp\[Book1.xlsx]Sheet1'!B3. The string with the reference created in this manner might be too long and inconvenient in use. The Workbook.Options.Save.CurrentFileName property of a referenced workbook enables you to specify a name that is easier to read, for example, "MyExternalWorkBook". Replace the corresponding item of the ExternalWorkbookCollection with an instance of the workbook with a custom CurrentFileName, and use it in external references instead of the file name, e.g.  [MyExternalWorkBook]Sheet1!B3.

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

public class TreeListHeaderMerger
   {
       private TreeList treeList;
       private TreeListColumn columnToMerge;

       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;
           Rectangle r = e.ObjectArgs.Bounds;
           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?

How come the view should be responsible of creating documents and panels? In a true MVVM design this should be the ViewModel's responsibility.

Added By: David Lemieux at: 12/5/2013 8:17:17 AM    

Is anyone from DevExpress monitoring comments on examples?

Added By: Alex Zeller (DevExpress) at: 12/6/2013 5:07:00 AM    

Hello David,
The View only creates root containers where dock panels are placed. This is a required step of creating the Docking UI.

Added By: David Lemieux at: 12/16/2013 2:00:09 PM    

Alex, I was refering to MainWindow.xaml.cs file. It has AddPanel_Click and AddDocument_Click methods, in which view models instances are created.

If the purpose of the example is to demonstrate how DX docking can be used with the MVVM pattern, then the DockLayoutManagerViewModel class should be responsible for creating / adding documents. Giving this responsibility to the view class goes straight against MVVM design rules, IMHO.

Added By: Alex Zeller (DevExpress) at: 12/17/2013 4:34:14 AM    

David, you're right. We have moved the code that creates Panels and Documents to View Models.

How to create a custom action type with a custom control (BarCheckItem), associated with it

December 31, 2000, 4:00 pm
$
0
0

This example demonstrates how to represent an action via the BarCheckItem. For this purpose, an ActionBase descendant (CheckableSimpleAction) is implemented. This is done because it is required to save the checked state of the action. CheckableSimpleAction uses a custom action item (CheckActionItem), which represents it in the UI via a BarCheckItem. Action item is a connector between the abstract entity Action and a particular UI element. When the form's menu is created, XAF creates action items for all actions placed to this form via action containers. This operation is performed by the BarActionItemsFactory and the ActionControlsSiteController. Since we have implemented a custom action type, it is required to implement a custom BarActionItemsFactory to assign an appropriate action item to actions of this type. The custom BarActionItemsFactory is registered via the custom factory provider (MyBarActionItemsFactoryProvider).
Note that in most cases, it is not required to implement a custom action and action item. It is sufficient to customize the existing action item via the BarActionItemsFactory.CustomizeActionControl event. This approach is demonstrated in the How to: Customize Controls Associated with an Action topic.
An example for ASP.NET is available here: How to create a custom action type with a custom control in Web.

How to sort a nested ListView at the business objects level, in code

This example demonstrates how to provide hidden and permanent sorting by a property in a nested ListView. Suppose we have Order and OrderItem classes that participate in an aggregated One-To-Many relationship.
We want to sort the collection of OrderItem objects by the ModifiedOn property, but do it in a way that end-users won't be able to see that the grid is sorted. Please see the sources of the Order class for more details on how to accomplish this. With this solution, sorting is implemented on the business objects level. Another variant is to use the approach from the How to sort a ListView in code example. This solution uses a specific ViewController.
Alternatively, you can use the Sorting property of the ListView application model element.
