EDIT: Disregard. I just re-built the solution and it cleared it up.

I just installed the 2010 SP1 release for VS 2010, loaded up a project, and updated everything. To make sure all was well, I grabbed a RadGridView from the newly created toolbox section and dragged it over to the design surface.

What I noticed different this time is that instead of adding this:

    
            xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"

it added this:

    
            xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

As a result of this, when I try to add columns to the GridView, like this:

    
            <telerik:RadGridView x:Name="radGridView1" > 
        
                <telerik:RadGridView.Columns> 
        
                </telerik:RadGridView.Columns> 
        
            </telerik:RadGridView>

I get the error in the title of this message:

The property 'telerik:RadGridView.Columns' is not declared as an attachable property.

I am still able to use the RadGridView fine using the normal xmlns with the assembly reference - just wanted to let you guys know that this is happening on a fresh install, so others might experience the same.

Thanks!
