Data binding ComboBox in GridView

[Ali]

I'm using the combobox in this example inside a grid as a celledittemplate:
<telerik:GridViewDataColumn Header="َArticle Description" Width="100"><telerik:GridViewDataColumn.CellTemplate><DataTemplate><TextBlock Text="{Binding DataContext.AccDocumentItem.Description1, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"/></DataTemplate></telerik:GridViewDataColumn.CellTemplate><telerik:GridViewDataColumn.CellEditTemplate><DataTemplate><telerik:RadComboBox IsEditable="True" DisplayMemberPath="SLStandardDescriptionTitle"ItemsSource="{Binding DataContext.AccDocumentItem.SelectedSL.SLStandardDescriptions, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"Text="{Binding DataContext.AccDocumentItem.Description1,Mode=TwoWay,RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"><i:Interaction.Triggers><i:EventTrigger EventName="DropDownOpened"><i:InvokeCommandAction Command="{Binding DataContext.SLStandardDescriptionsDropDownOpenedCommand, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}" CommandParameter="DLType2"/></i:EventTrigger></i:Interaction.Triggers></telerik:RadComboBox></DataTemplate></telerik:GridViewDataColumn.CellEditTemplate> </telerik:GridViewDataColumn>

I need to present a grid where one column is a combobox. The user can select one value from the list or enter a new value, the problem is that selected row is repeated in all rows. Can you please tell me what I'm doing wrong?
Your time much appreciated!

Hi Ali,

Thank you for your interest in RadGridView control.

Instead of using GridViewDataColumn and RadComboBox inside it, the RadGridView expose a combobox column which you can use. You can take a look at the ComboBox Column help article in our documentation which describes its properties and how you can populate the column with your data.
