WPF Databinding issue

Question

I'm using a RadGridView (Telerik). I'm trying to make a column editable only for certain rows, but what I'm trying doesn't seem to be working and I'm not sure how to do it.

My grid is this:

<telerik:RadGridView HorizontalAlignment="Left" Margin="12,12,12,12" Name="radGridView1" VerticalAlignment="Top" ItemsSource="{Binding FeedList}" ShowGroupPanel="False" AutoGenerateColumns="False" ShowInsertRow="True" EditTriggers="Default">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn Header="Feed" DataMemberBinding="{Binding Path=Name}" Width="150" IsReadOnly="{Binding Path=ReadOnly}" />
        <telerik:GridViewDataColumn Header="Url" DataMemberBinding="{Binding Path=Url}" Width="*"/>
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

The bound object has a property, but the Path for the IsReadOnly binding is relative to the DataContext for the form and not the bound object. How would I make it relative to the bound object in this case?

In case anyone comes across this on a search. The answer is the GridView's datacontext is bound to the collection it's displaying and doesn't have access to the Window or UserControl's datacontext.

Thomas Levesque has a blog entry on the subject. He puts together a BindingProxy class that you can use to pass in the datacontext to the radgridview.

Intellisense must have been messed up. Somehow missed the IsReadOnlyBinding property of GridViewDataColumn, which does exactly what I want. Not sure why IsReadOnly couldn't do it, though.
