Greetings,

The RadGrid's GridTemplateColumn seems to break between .NET35 and .NET4+. Running the simple code below works fine for .NET3.5 and breaks for .NET4+, see the attached .PNGs.

Any idea why?

Thank you,
Gary.

Hi Gary,

I have prepared a sample RadGrid web site to test the described behavior and it works as expected on my end. Can you please run the attached application and instruct me the exact steps I need to follow to reproduce the issue?

Hi Eyup,

The issue occurs when you add a GridTemplateColumn and use a DataTable for the DataSource. My original post said "Framework Issue" because when I switched frameworks to 3.5, the Grid did not fail. I should mention this occurs in VS2013 with .NET4+. This error does not occur in VS2012 under any framework.

At this point I believe there is a bug in the RadGrid (2013.3.1015) when using GridTemplateColumn with .NET4+ in VS2013 using a code behind generated datasourse. I notice others have posted similar problems without resolution.

I've switched to VS2012 until this is resolved.

Thanks,

Gary.
