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

[Michael Ruddick]

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!

I'm getting the same problem.
Any solutions out there?
