Hi,

I have a ListBox in the DataTemplate of an AgDataGrid Column. I want to be able to bind the ItemsSource to another collection of objects but cannot seem to get this working.

I am battling to get a handle on this StaticResource concept but from reading this http://msdn.microsoft.com/en-us/library/cc189045(VS.95).aspx I understand that I can define a Resource and then let the ListBox point to that.

I have not been able to make this work though, the below example just raise an exception after a while. 

In the constructor I have this line of code:

this.Resources.Add("DocumentTypes", DocumentTypes); //DocumentTypes is a List of DocumentType with a DocumentTypeKey field

And the below XAML for the Grid

<grid:AgDataGrid x:Name="grid" Margin="8,0,8,8" >
              <grid:AgDataGrid.Columns>
                   <grid:AgDataGridColumn FieldName="FileName" Width="248"/>
                <grid:AgDataGridColumn FieldName="DocumentTypeKey" Width="108">
                    <grid:AgDataGridColumn.DisplayTemplate>
                        <ControlTemplate TargetType="ListBox">
                            <ListBox x:Name="lbDocumentTypeKey" ItemsSource="{Binding Path=DocumentTypeKey, Source={StaticResource DocumentTypes}}" Height="25"/>
                        </ControlTemplate>
                    </grid:AgDataGridColumn.DisplayTemplate>
                </grid:AgDataGridColumn>
            </grid:AgDataGrid.Columns>
         </grid:AgDataGrid>

Thanks in advance,

Anton
