Hello,
We just updated our telerik-controls to the latest version (2011 Q1). Now I am getting an exception when trying to use the gridview grouping.
This is the xaml for my gridview :
<telerik:RadGridView AutoExpandGroups=
"True"
ShowColumnHeaders=
"False"
ItemsSource=
"{Binding SelectedCategoryDataItems}"
CanUserFreezeColumns=
"False"
CanUserReorderColumns=
"False"
CanUserResizeColumns=
"False"
EditTriggers=
"None"
IsReadOnly=
"True"
AutoGenerateColumns=
"False"
ActionOnLostFocus=
"None"
RowIndicatorVisibility=
"Collapsed"
ShowGroupPanel=
"False"
HorizontalAlignment=
"Stretch"
Grid.Column=
"1"
RowStyle=
"{StaticResource GridItemStyle}"
/>
The SelectedCategoryDataItems property is a QueryableCollectionView. The groupdescriptor is added from the viewmodel code-behind :
DataItems.GroupDescriptors.Add(
new
GroupDescriptor() { Member =
"Status2"
});
When I set AutoExpandGroups = True, the following exception is immediately thrown (application doesn't start) :

Setting AutoExpandGroups to False gives the following exception in the output-window when I'm trying to expand a group from the UI :
