Hi,

I am creating an application using a number of the 2009 Q2 Release components with Silverlight 3.0 Release. When I introduce a GridView I get the following exception. Any suggestions?

System.Windows.Markup.XamlParseException occurred

Hi Mike

If I remember well (cause I got that kind of problem like twice a week), it's because the System.Windows.Controls.Data assembly from your Silverlight project is either missing or still in the 2.0.0.0 version.

Check your references, if you don't see the file, you'll need to add it (click right -> add reference)
If it is there, you can check the version in the property window (version), and update is if it isn't 2.0.5.0

It's usually located in the folder C:\Program Files\Microsoft SDKs\Silverlight\v3.0\Libraries\Client\System.Windows.Controls.Data.dll

Hopes that helped

Hi Ludovic

In Visual Studio, the reference to  System.Windows.Controi.Data reports

Rentime Version v2.0.50727
Version 2.0.5.0
I also have Specific Version  = false;

I believe I only have Silverlight 3.0 Release installed.

This was working with pre-release versions of Silverlight 3 and also development versions from Telerik prior to Q2 2009.

Hi guys,

Our latest internal build (which is compatible with SL 3 RTW)  does not require  System.Windows.Controls.Data.

Hi there,
I am also having the same problem. I am running a silverlight 3 application and I am using version 2009.2.701.1020.

I have checked in my references that System.Windows.Controls.Data is referenced and it is referencing the correct version.

What am I missing?

Thanks
Shane

Hi.
I have the same problem.
I use  telerik compile version 2009.2.701.1020. Also add to project  System.Windows.Controls version 2.0.5.0.
But project crashed with exception:

System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Controls.Data, Version=2.0.5.0, Culture=neutral, PublicKeyToken=3d8c6023c75a3242' or one of its dependencies. The system cannot find the file specified.

I need help. What I do wrong?

Hello,

You have SL2 compatible binaries in SL3 project. To fix this you will need to download at least Q2 SP1!
