    I have just purchased the Q1 release, and I can't seem to get most of the RadControls to display in design mode in either VS2008 or Blend. I am using Visual Studio 2008 SP1 and Blend 2 SP1 on Vista 32 SP1.

    I first noticed the problem with the examples. Finally, I created a fresh Silverlight application and added just single RadControls to the default Grid, and I get either a blank preview or an exception stack trace. However, if I compile and run, the controls appear and seem to function correctly. Is it possible there is a problem with the *.Design DLL's?

    I initially installed the MSI version, then replaced the DLL's with the ones in the ZIP download...same results. I remember using the trial version of the previous release and I didn't have any problems like this. Incidentally, this is not a case of old DLL's hangiing around from the earlier trial...I am using a freshly re-formatted and re-installed version of Vista 32 (done for an unrelated reason).

    Here is the exception trace after adding just a RadDocking control:

    Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

    Hello David,

    I will start with design-time of our examples. There seem to be some issue with Visual Studio that prevents our examples from showing in design time. We found solution for this problem so for the next service pack all our examples will be have design-time in Visual Studio and Blend.

    For Blend design time - you should update your copy of System.Windows.Controls.Data.
    More information here:

    About RadDocking design time we found some issues with Blend that we will fix for the next service pack. If this is a show-stopper for you just let me know and I'll send you the hotfix.

    It seem that there are some known issues with Silverlight Design-time in Visual Studio.
    For example:

    Preview window shows error if reopened

    Occasionally, when the Preview window or XAML View opens, an error is displayed. This can occur if the last instance of the Preview window was closed and reopened without rebuilding the project. To work around this issue, try the following:

    ·          Always leave open at least one view of a XAML document in your project.

    ·          Rebuild the project.

    ·          If your project will not build, close and reload the project, or close and reopen Visual Studio.

    You can read more about Silverlight known issues here:

    I hope that this post will bring some light over the design-time issues that you have.
    Let me know if you have more troubles. I'll be glad to help.

    All the best,

    Hi Mindtrio,

    All issues should had been resolved until this point. Try downloading the latest version of the controls and tell us if you experience any problems with it.
