RadGridView fails when specifying StyleManager.Themes

[Mark Wells]

Hi,

I am getting an error when specifying the StyleManager.Themes property in the RadGridView. I was not getting this before but I did obtain the dll's for 2010.2.714.1030. This problem is happening with this set of dll's. I would really like to make it work with this set because it contains a fix that I have been waiting months for telerik to fix.

I have attached a screen shot of the error. I also have a mini project that demonstrates the error, but it should be sufficient to just include the below code to re-create, since the code is very basic. All you have to do is try and run it to get the error.

Hello Mark Wells,

We have prepared a sample project with the code that you supplied but we are not getting any error. I have attached the sample project. Can you modify it so that it displays the error. Thanks in advance.

P.S. Do you have a reference to the theme assembly?

All the best,
Ross

Hi Ross,

The sample project you sent uses the Telerik dll's for Silverlight 4 (2010.2.714.1040). I want to use the Silverligt 3 dll's that Telerik provides for download (version 2010.2.714.1030).

Yes, I do have a reference to the Theme dll (Telerik.Windows.Themes.Office_Silver.dll)

Please try again with the Silverlight 3 dll's.

Thanks,

Mark

Hello Mark Wells,

I have updated the same project to use the SL3 assemblies. But I am still not getting any error. What am I doing wrong? Please, find the project attached.

Best wishes,

Ok, so I replaced the dll's in my project with the ones that you provided in your sample project. It finally works!!!!!

And the bugs in the Telerik controls that I have been chasing after since March are now all fixed. It has been a long haul......

Thanks very much,

Mark
