I'm trying to add a checkbox to grouped rows, that would check all checkboxes in that group (or uncheck) when clicked.

I am trying to do it like this...

 

 

RadGroupDescription rgd = new RadGroupDescription();

 

 

CheckBox cb = new CheckBox();

 

cb.Checked +=

new RoutedEventHandler(cb_Checked);

 

rgd.DisplayContent = cb;

dataGrid.GroupDescriptions.Add(rgd);

However, I keep getting this error regarding the first line.... 
Error 3 The type 'System.ComponentModel.GroupDescription' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Windows.Controls.Data, Version=2.0.5.0, Culture=neutral, PublicKeyToken=3d8c6023c75a3242'. C:\pwSource\Silverlight2\Dev\Framework\PetroWEB\Reports\PWDataGrid.xaml.cs 415 13 PetroWEB.Silverlight

I have the dll referenced from the default location..  (c:\Program Files\Microsoft SDKs\Silverlight\v2.0\Libraries\Client\System.Windows.Controls.Data.dll) But it won't let me add a 'Using' Statement...

the only intellisense option at System.Windows.Controls.    is Primitives?

Hello Casey,

Could you try using the System.Windows.Controls.Data assembly that is distributed with our suite?
That should fix the problem.
