Checkbox column in GridView using MVVM

[Brian]

<telerik:GridViewColumn>

<telerik:GridViewColumn.Header>

   <CheckBox x:Name="ckbSelectAll" IsChecked="{Binding ElementName=LayoutRoot, Path=DataContext.SelectAll}" IsThreeState="False">

 </CheckBox>

</telerik:GridViewColumn.Header>

<telerik:GridViewColumn.CellTemplate>

   <DataTemplate>

       <CheckBox IsChecked="{Binding IsSelected, Mode=TwoWay}" />

   </DataTemplate>

</telerik:GridViewColumn.CellTemplate>
</telerik:GridViewColumn>

I have the following column in my RadGridView.  I want to be able to select all columns based on a checkbox in the header or select single columns via a checkbox in the row.  The 'IsSelected' property is working as it I would expect, however the SelectAll property is not.  SHOULD I be able to bind this property?  I get no binding errors but also see no response to a change in the IsChecked property.

I can't use a GridViewSelectColumn b/c I need to be able to get the result of the checkboxes in my view model.

Any ideas how to accomplish this?
Tks.
