Databinding to column ActualWidth in nested grid

[James]

I have a radgridview with a nested radgridview in the RowDetails.
I would like to bind a column width in the nested gridview to a
column ActualWidth in the parent gridview. I tried using a simple 
elementName binding and giving the column a name, but that doesn't 
seem to work. Is there a better way to do this, or another way to
reference the grids column that I am missing.

Cheers,
James

<DataTemplate x:Key="DetailGrid">

    <telerik:RadGridView>      

        <telerik:RadGridView.Columns>

            <telerik:GridViewDataColumn

                Width="{Binding ActualWidth, ElementName=MainGridFirstColumn}" />          

        </telerik:RadGridView.Columns>

    </telerik:RadGridView>

</DataTemplate>

 

<telerik:RadGridView Name="MainGrid" RowDetailsTemplate="{DynamicResource DetailGrid}">

            <telerik:RadGridView.Columns>

                <telerik:GridViewDataColumn

                                Name="MainGridFirstColumn"

                    Width="*"/>

            </telerik:RadGridView.Columns>

</telerik:RadGridView>

Hello,

 Maybe it will be better to use RadTreeListView in your case if you have the same columns in parent and child grid. 

All the best,

Using x:Reference instead of ElementName worked.
