Error in Blend 3

[Ruban]

HI,
I'm getting the following errror in Blend 3:
xmlns:telerikGridView="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView" 

Works fine in Visual studio,

Hi Ruban,

Could you post the original error message which will help us rosolve your problem? The text in your previous post is just a namespace mapping declaration which does not provide enough information.

Thanks in advance.

Fixed, I created a new project with the same references and seems to work. Must have used older versions of controls.

Hi Ruban,

I cannot simulate this exception in Expression Blend 3. I'm attaching a sample project based on your code snippet and everything works fine on my end.
Can you provide me with more detailed information how to simulate this issue?

One possible reason for such an error is that Expression Blend 3 needs Silverlight 3 and of course Telerik assemblies built on Silverlight3. Can you confirm that you have installed Silverlight3?

Thanks Nedyalko,  I created a new project with the same references and seems to work. Must have used older versions of controls.
Seems to work now.

I had the same problem. one day it was working good, the next day all of the telerik references were not being seen. I noticed that it happened right after a telerik update. so I checked the .csproj file to find:

 <Reference Include="Telerik.Windows.Controls.GridView, Version=2010.3.1314.1040, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL">
      <SpecificVersion>False</SpecificVersion>
 <HintPath>..\..\..\..\..\AppData\Roaming\Telerik\Updates\RadControls_for_Silverlight4_2010_3_1314_Dev_hotfix\Binaries\Silverlight\Telerik.Windows.Controls.GridView.dll</HintPath>
    </Reference>

So I changed them to simply be:
<Reference Include="Telerik.Windows.Controls.GridView" />


Now all is well.
