I have a SilverLight app. On one of my forms I am trying to display a RadGridView with several columns including a column with a GridViewComboBoxColumn.

The GridViewComboBoxColumn works and displays the dropdown for each row and it's bound correctly to the Grids datasource.

 

The problem is that the GridViewComboBoxColumn only displays after I double click on the column. Then the drop down appears on each row correctly. But when I move focus off the GridViewComboBoxColumn column, the column disappears again. If I tab back on the column, the label appears as expected, etc....

 

Here is my GridViewComboBoxColumn xaml:

 

                                <telerik:GridViewComboBoxColumn Header="My Header" MinWidth="200"

                                DataMemberBinding="{Binding MyID, Mode=TwoWay}"    ItemsSource="{Binding Model.MyListItems}"                                 SelectedValueMemberPath="MyListID"  DisplayMemberPath="MyListTitle">   </telerik:GridViewComboBoxColumn>

 

Why does the column disappear if it doesn't have focus?

 

No answers yet. Maybe you can help?
