Can I bind a GridViewComboBoxColumn.ItemsSource to the selectedItem in another GridViewComboBoxColumn?

[Marian]

I have a form with the following two ComboBoxes:

<ComboBox DisplayMemberPath="dgpGroupDesc" SelectedValuePath="dgpID" Name="cboGroupID" ItemsSource="{Binding ElementName=docGroupDomainDataSource, Path=Data}"></ComboBox>
<ComboBox DisplayMemberPath="dgpSubDesc" SelectedValuePath="dgpSubID" Name="cboSubGroupID" ItemsSource="{Binding ElementName=cboGroupID, Path=SelectedItem.DocSubGroups}"></ComboBox>

With this, the ItemsSource of the second combo box is filtered based on the selected item of the first. Is there anyway to do this in a GridView? I've tried with the following but there are no items in the second combo box:

<telerik:GridViewComboBoxColumn UniqueName="ebookTab" Header="eBook Tab" DataMemberBinding="{Binding dgpID}" DisplayMemberPath="dgpGroupDesc" SelectedValueMemberPath="dgpID" ItemsSource="{Binding ElementName=docGroupDomainDataSource, Path=Data}"/>
<telerik:GridViewComboBoxColumn Header="Document Group" DataMemberBinding="{Binding dgpSubID}" DisplayMemberPath="dgpSubDesc" ItemsSource="{Binding ElementName=ebookTab,Path=SelectedItem.DocSubGroups}" SelectedValueMemberPath="dgpSubID"/>

Thanks for the quick response. I'll take a look at the sample project and see if I can get this working.
