How to access a nested ListView from the parent DetailView's controller and parent DetailView from the nested ListView's controller

April 24, 2012, 8:49 am
$
0
0

This example is based on the following facts:


1. The nested ListView is shown in the parent DetailView via the ListPropertyEditor. The ListPropertyEditor class has the Frame property that returns the nested frame and the ListView property that returns the nested ListView. To get the ListPropertyEditor, use the DetailView.FindItem or DetailView.GetItems method.


2. The nested list view's frame is represented by the NestedFrame class that has the ViewItem property, which returns the ListPropertyEditor from the parent DetailView. It is possible to access the parent DetailView via the ListPropertyEditor's View property.


Note that this code is required only if you need to access views and frames. If you need to access child business objects from the parent DetailView, simply get the DetailView's CurrentObject, cast it to the corresponding type and use its collection property. If you need to access the parent object from the nested ListView, use the PropertyCollectionSource.MasterObject property, as shown in the How to: Access the Master Object from a Nested List View help topic.

This example illustrates how to use the ASPxPivotGrid.CustomFieldValueCells event to totally hide an empty Grand Total column.

Question Comments
Added By: Ram dasari at: 7/10/2014 4:54:51 AM    

This code does not hide an  empty grand total column but instead hides all columns.

Added By: Constant (DevExpress Support) at: 7/10/2014 7:20:38 AM    

Yes, this is the expected behavior. If you wish to hide specific grand total columns corresponding to a specific Data Field, it is necessary to set the corresponding PivotGridField.Options.ShowGrandTotal Property to false. Please try this solution and let me know your results.

How to use DevExpress themes in a WPF Application

July 11, 2014, 2:34 am
$

This example demonstrates all common ways of using themes in your application.

DevExpress provides multiple themes that can be applied to all DevExpress WPF controls and some standard controls (GroupBox, ScrollViewer, Scroll, RadioButton, Button, ListBox, Slider, TabControl, Separator, ToggleButton, RepeatButton, Label, ListBoxItem, TabItem, ToolTip, etc.). All built-in themes are described in the following article: DevExpress WPF Themes.

The easiest way to apply a particular theme to the application is to specify the static ThemeManager.ApplicationThemeName property.

To set a theme for a specific element, use the ThemeManager.ThemeName attached property:

 

[XAML]
xmlns:dx=”http://schemas.devexpress.com/winfx/2008/xaml/core”<TextBoxName="textBox1"dx:ThemeManager.ThemeName="MetropolisLight"Width="120"Height="23"/>

 

In this case, the theme will be applied to the element and all its child elements.

Keep in mind these simple rules when applying DevExpress themes:

1. The ThemeManager.ApplicationThemeName property has lower priority than the ThemeManager.ThemeName property set locally.

2. The ThemeManager.ThemeName property value set for a parent element may be changed for its child if you explicitly specify the ThemeManager.ThemeName property for it.

In some cases, you may need to retrieve a list of all available DevExpress themes. The static Theme.Themes property contains this information.

How to export GridView data to different rich text formats

This example is standalone implementation of the online Grid View - Exporting Data demo.
It illustrates how to export the GridView 's content to several rich text formats via the ExportTo*** methods.

This example is an illustration of the KA18639: How to export GridView rows and keep end-user modifications (such as sorting, grouping, filtering, selection) KB Article. Refer to the Article for an explanation.

Please note the following key moments:
- The GridView Extension should be defined via a separate PartialView without any additional tags (see the Using Callbacks help topic for more information);
- The GridView's PartialView should be wrapped within a form in order to apply the client layout state (sorting, filtering, etc.);
- An export trigger should submit this form to the corresponding Controller Action (i.e., make a POST request);
- The GridViewSettings (especially the Name property) should be the same in PartialView and Controller;
- The datasouce/Model should be the same in PartialView and Controller.

How to bind SchedulerControl to SQL Server database

This example demonstrates how to bind the SchedulerControl to a database located in MS SQL Server 2005.

The basic steps to create this example are equivalent to the steps described in Lesson 1 - Bind a Scheduler to Data. However, several additional steps are added to demonstrate more SchedulerControl capabilites:

- Resources for appointments
Besides the appointment mappings, resource mappings are defined in the SchedulerStorage. A separate TableAdapter is used to retrieve resources from the database.

- Resource sharing
The AppointmentStorageBase.ResourceSharing Property value is set to true (note the It is impossible to set ResourceSharing property to true via XAML bug report).

To test this example locally, you should setup our CarsXtraScheduling sample database in your SQL Server instance (you can download the corresponding *.sql scripts from the How to bind ASPxScheduler to MS SQL Server database example).

ASPxGridView - How to implement cascading comboboxes in Batch Edit mode

July 1, 2014, 5:05 am
$
0
0

The concept of cascading combo boxes requires sending a callback to the server to get data for the second editor based on the first editor's selected value. 
In the meantime, it's impossible to send callbacks for built-in editors and it's necessary to use the EditItemTemplate (see ASPxGridView - Batch Edit - Support a scenario when GridViewComboBoxColumn is used in callback mode).
A basic scenario of this approach requires the following steps:
1) Use the client-side ASPxClientGridView.BatchEditStartEditing  and ASPxClientGridView.BatchEditEndEditing  events  to provide the template combo box with values.
2) Handle the SelectedIndexChanged event to send callbacks if it's required.
3) Handle the ASPxClientComboBox.EndCallback event for the second editor to apply the selected item after a callback.
4) Handle the ASPxClientGridView.Init  and ASPxClientGridView.EndCallback events  to initialize and reset global variables responsible for data providing logic after the grid was refreshed. 
 
The attached example illustrates how to implement all these steps.

How to register a custom filter function and use it in GridControl

September 15, 2011, 7:35 am
$
0
0

Starting from version 11.1 it is possible to register a custom function globally .

To create this function, it is necessary to implement the ICustomFunctionOperatorBrowsable interface. If you wish your custom function to be evaluated on the server side (for instance, when Server Mode is used) it is necessary to implement the ICustomFunctionOperatorFormattable interface.
Finally, to register a custom function you should call the CriteriaOperator.RegisterCustomFunction method with your custom function instance at the application startup.

To show a custom function, for instance, within a column DateTime filter dropdown handle the GridView.ShowFilterPopupDate event. In this event handler create a FunctionOperator instance and pass your custom function name to its constructor. Then, add this FunctionOperator to the e.List collection.

Also, it is possible to use a custom function within FilterEditorControl. To use the FilterEditorControl rather than a regular FilterControl in a grid, set the GridView.OptionsFilter.DefaultFilterEditorView property to any value except for Visual. So, you can enter your function in the FilterEditorControl by choosing the Text tab.

This example illustrates how to add a custom function that will determine whether or not a processed date is a day off and show it in a column DateTime filter dropdown.

How to refresh the Field List in the End-User Designer

This example demonstrates how to programmatically update the Field List in the End-User Designer. This may be required when a data source is created and bound to a report at runtime, and isn't present in the designer host of the End-User Designer. For instance, this situation occurs when a data source is represented by a list (e.g. ArrayList), as demonstrated in the sample below.

To accomplish this task, we've introduced the FieldListDockPanel.UpdateDataSource method, which should be called after assigning a data source to a report.

Question Comments
Added By: BGood2 at: 3/27/2014 3:59:31 PM    

Tried this sample with v13.2.8 in Visual Studio 2012 on Windows 7 32 bit VM. Menu item "Bind to a DataSource" is disabled after the app starts.

If I bypass the code in Form1_Load and don't call xrDesignPanel1.ExecCommand(ReportCommand.NewReport);, the menu item is enabled, but the code in BindReportToData() fails because xrDesignPanel1.Report is null.

Suggestions?
