If adding a DataFormComboBoxField an exception occurs in Expression Blend.
Please have a look at this screencast.

Thanks for your assistance

Hi Daniel,

 

What is the version of RadDataForm you are curently using? I have tried to replicate such a behavior with binaries as part of our latest official release Q2 2011, but I was not able to. What happens when you add onto an empty design surface single DataFormComboBoxField? 
 

Best wishes,

Hello,

I am using Q2 2011. My dev box is Windows 7, 64 bit, english.
Please note that I am not referencing the Telerik DLL from the default installation folder. I copied them to my solution folder (C:\Projects\SOS.Lucy\LucyLabs\SOS.LucyLab005\Binaries\Telerik)

The silverlight project file inlcudes HintPath and looks like this.

<Reference Include="Telerik.Windows.Controls, Version=2011.2.712.1040, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL">
  <HintPath>..\Binaries\Telerik\Silverlight\Telerik.Windows.Controls.dll</HintPath>
</Reference>
<Reference Include="Telerik.Windows.Controls.Data, Version=2011.2.712.1040, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL">
  <HintPath>..\Binaries\Telerik\Silverlight\Telerik.Windows.Controls.Data.dll</HintPath>
</Reference>
<Reference Include="Telerik.Windows.Controls.GridView, Version=2011.2.712.1040, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL">
  <HintPath>..\Binaries\Telerik\Silverlight\Telerik.Windows.Controls.GridView.dll</HintPath>
</Reference>
<Reference Include="Telerik.Windows.Controls.Input, Version=2011.2.712.1040, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL">
  <HintPath>..\Binaries\Telerik\Silverlight\Telerik.Windows.Controls.Input.dll</HintPath>
</Reference>
<Reference Include="Telerik.Windows.Data, Version=2011.2.712.1040, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL">
  <HintPath>..\Binaries\Telerik\Silverlight\Telerik.Windows.Data.dll</HintPath>
</Reference>

If I am overriding the HintPath by adding a Silverlight Projects settings reference path which references the default Telerik installation folder "C:\Program Files (x86)\Telerik\RadControls for Silverlight Q2 2011\Binaries\Silverlight\" everything works fine. If I am referencing the same DLLs but copied to the C:\temp, I get an error again.

This screencast might explain the problem better.

Please be informed that I created another ticket/forum post which describe similar Expression Blend behaviours if the Telerik DLLs are not located in the default installation folder.

Thanks for your assistance

Hello Daniel,

 
We have spent some time to investigate what might be causing such a behavior. For the time being we are not able to reproduce the exception using even the screencast provided. I believe that the origin of this issue is the path of the referenced assemblies. May you please try the approach suggested in the ticket with ID 430578 and let me know whether the issue with DataFormComboBoxField still persists? Furthermore in order to keep our support communication clean and consistent please keep the already opened tickets synchronized on the corresponding topic. 

All the best,
Vanya Pavlova
