GridViewComboBoxColumn - Grouped items?

[keepITcool]

I have a simple RadGridView (no filtering/no grouping)
I have a Column defined as below with the ItemsSource bound to a CollectionViewSource with a single PropertyGroupDescription.
I want to show the items in the combo popup grouped. 

<telerik:GridViewComboBoxColumn
    DataMemberBinding="{Binding Left}"
    DisplayMemberPath="Name"
    Header="Left"
    IsFilterable="False"
    ItemTemplate="{DynamicResource itmTemplate}"
    ItemsSource="{Binding LeftCVS.View}"
    SelectedValueMemberPath="Index"
    GroupHeaderTemplate="{DynamicResource hdrTemplate}"
    UniqueName="left" />

 

For a normal RadComboBox I can do it by setting the GroupStyle. Can't find the equivalent on the GridViewComboBox.

Help!

Hello Jurgen,

May I ask you to check out the following thread: Grouping item inside ComboBoxColumn where a similar question was discussed? Additionally you can check out the Grouping Items forum thread where another approach was discussed. Even though the approach is for the RadComboBox, it should be relevant for the GridViewComboBoxColumn as well. 

Please, give the suggestions in the above topics a try and let me know if they are suitable for your scenario.

I solved it by dumping the ComboBoxColumn.
I know have a standard GridViewColumn... with CellTemplate (basic stackpanel), CellEditTemplate with a RadcomboBox. Much more control and I got what I want.

Worked around it and found a solution. But it's still strange that a RadComboBoxColumn doesn't fully expose the RadcomboBox that you know is there..

Hello Jurgen,

I am glad to hear that you were able to find a suitable solution. Thank you for sharing your approach.

As for the GridViewComboBoxColumn it exposes most of the properties defined by the RadComboBox. What you have as an option to further modify the RadComboBox is to define a style targeting RadComboBox and set it to the EditorStyle property of the column. Of course, using a standard column with custom CellTemplate and CellEditTemplate is also a valid option.
