This column type is typically used to provide a lookup into some set of relatively static values. Set the DataSource property to the data source that contains possible values to choose from. Set the DisplayMember property to the column of the DataSource that should be displayed in the drop down list. Set the ValueMember property to the column of the DataSource that should be used to update the cell within the grid represented by the FieldName property.
Values will display in the column only if the value in FieldName is within the range of values provided by the ValueMember field values. However, if you need to perform the sorting according to the DisplayMember instead, you should set the DisplayMemberSort property of the column.
GetLookupValue Returns the look-up value for the specified cell value. GetDefaultEditorType Returns the default editor type. GetDefaultEditor Returns the default editor. If you want to set initial values, you should match the GridViewComboBoxColumn to a column which has appropriate values in it. This event is fired when the initialization of an editor is done.
The following example demonstrates a case where the combo box is bound to a column with string values in the data source. In this case the DisplayMember and ValueMember properties are the same, and you need just an array of strings as a data source to the ComboBoxColumn those strings should be equal to the possible values in the data source :. The example below extends the previous sample, where we bound the combo column to array of strings, by adding a text box column and another combo column, this time bound to a collection of custom object.
The first step is to define your grid data source, fill in some data, and set column auto-generation to false so that the grid does not generate its columns from the data source. The BindingList consists of objects having properties for your value and display members. The "Another ComboBox column" in the grid data source is of type int and our custom object has a property of type int.
So in order to link the data source field to our custom object integer field, we have set the ValueMember to "Id". You have to handle the EditorRequired event. This event is fired every time when an editor needs to be shown. A sample code demonstrating this technique:. All Rights Reserved. See Trademarks for appropriate markings. UI for WinForms.

Telerik RadGrid supports automatic extraction of values from the form template. Thus the automatic data-editing in this case does not require any extra coding but merely declaring two-way binding expression for each input control.
This example also demonstrates the mechanism for setting default values for the edited fields in the insertion form. Note that FormTemplate custom edit form is not supported with simple data-binding calling DataBind. See the Simple data binding demo from the Populating with data section for more info about the limitations of this binding mode.

In order to use the RadGridView control in your projects, you have to add references to the following assemblies:. Before proceeding with adding RadGridView to your project, make sure the required assembly references are added to the project. If you run the application, you will see an empty grid with no columns and rows as demonstrated in Figure 1. In order to populate the RadGridView control with data, you should create a collection of business objects.
For the purposes of this example, create a new class named Club and add several properties to it, as shown in Example 3. If you want to support two-way binding, your Club class should implement the INotifyPropertyChanged interface and raise the PropertyChanged event every time a property value changes. It resides in the Telerik. Controls namespace. Now that you have prepared the needed sample data, it is time to bind RadGridView to it. The local namespace in the example corresponds to the namespace where MyViewModel resides.
Alternatively, you can set the ItemsSource property in code-behind, as demonstrated in Example 6. Running the application containing the code from Examples 1 - 6 will result in a populated RadGridViewlike in Figure 2. You can read more about configuring the data bindings here.

The RadGridView from the examples above contains three columns, one for each of the properties of the Club class. RadGridView automatically generates these columns. If you want to stop the columns auto generation and define the columns that you want to be visible manually, set the property AutoGenerateColumns to False.
Example 7 demonstrates how you can manually prevent the automatic generation and define columns. The code in Example 7 is shown in Figure 3.
The second named "Established" is bound, respectively, to Established. As a result, your grid control will have only two columns and no other column will be added because the AutoGenerateColumns property is set to False. You can read more about RadGridView columns here. You can disable sorting for a specific column by setting its IsSortable property to False. You can disable grouping for a specific column by setting its IsGroupable property to False.
The controls from our suite support different themes.
You can see how to apply a theme different than the default one in the Setting a Theme help article. Changing the theme using implicit styles will affect all controls that have styles defined in the merged resource dictionaries. This is applicable only for the controls in the scope in which the resources are merged. Choose between the themes and add reference to the corresponding theme assembly ex: Telerik.

This is being done by specifying a hierarchical grid in my XAML. Everything works just fine when you click on the row and expand the subgrid but the selectedItem of the initially selected row does not seem to change.
An example would be selecting row 1 of the grid initially and then expanding row 4 to display the subgrid. The subgrid is displayed but the selectedItem is still row 1. The desired behavior is for row 4 to be the selectedItem once it is expanded to display the subgrid. Can anyone point out what exactly is going wrong over here. Learn more.

The logic does look like something that will solve the problem. But seems like the IsExpandedChanged event is not available for the parentRow. Has it been added to a later version of Telerik? Indeed this event is added in Q3 SP1 - more info here: telerik. Windows; using System.

The car details are displayed with the help of the NestedViewTemplate. NET Panels that are switched dynamically at runtime.
The columns in this RadGrid use three different filter setups:. When working with DataGrids, fast loading of large data while having advanced Excel-like operations has always been a challenge. NET Grid to eliminate this tradeoff. Codeless databinding, rich client-side operations, and a myriad of features topped with unbeatable performance is what defines the Telerik RadGrid for ASP. NET AJAXa comprehensive toolset taking care of the common functionality of your application, while leaving you with more time to work on its business logic.
The multi-column headers are also demonstrated here. All the columns are grouped within parent groups which help the visitors easily distinguish the information they need. The data binding is performed within the NeedDataSource event thus taking advantage of the advanced data-binding capabilities offered by RadGrid. UI for ASP.
