Hello george,

I managed to reproduce the error at some point after writing the XAML of RadWindow, however after rebuilding the project it disappeared and I was not able to reproduce it anymore. So could you try to rebuild the project or restart Blend and see if this will help.

All the best,

thanks

Hi george,

I have not used any specific build sequence. Just created simple project in blend with just a RadWindow in it then when set the theme only to the window (not global) at first I got your error. Then just build the solution and the error disappeared.

We will try to investigate the problem further and try to fix it.

Kind regards,

thanks, is there any alternative solutions? its a pain to use vs to do the UI

i used to create a new project and link the existing xaml to it and it works

if i open the project solution file directly, it will show the same error no matter what i did.

regards

Hello,

Currently we are not aware of other solutions but I do agree that styling controls in VS is a pain. Can you share some more information with us about the version of blend you are using and wether the problem appears after upgrade of the controls (like moving from 2010 Q3 to 2011 Q1 or 2011 Q1 to 2011 Q1 SP1)? If we could reproduce the issue we could try to find a solution as well as upgrading Blend may help.

All the best,

Hello George,

We tested a few scenarios on theme application and we could not reproduce the issue. I tested the latest post of yours and it updates properly in design time in Blend. I also tested UserControls with Windows7Theme from a PRISM solution with shared resources. Again, I did not get the mentioned exception.  I suppose that this might be an Expression Blend  version issue. The version of Blend that I used for testing is: Expression Blend 4 + SketchFlow, v. 4.0.20525.0.

Please, note that if Windows7Theme is set as a resource and is located outside the UserControl which uses this resource, the design-time will not display Windows7Theme, it will display the default Office Black theme. Still, it will not throw an exception, either.
The inline theme application with telerik:StyleManager.Theme="Windows7Theme" works just fine in the same scenario.

If you could set up a simple working project that reproduces the issue, it will be very helpful for us to test.


Best wishes,
Dani
