 We had RadControls for ASP.NET AJAX 2010 verstion when this app was first created. ASPX file has a simple RadGrid in it and everything worked fine. 

Beginning this year we found out RadGrid in my App is not working with IE10. Telerik suggested us to upgrade to 2013 version.Then we did upgrade.

Now we are haveing the latest version of RadControls (2013 Q2). The .net framework is 3.5. I copied all dll files from C:\Program Files\Telerik\RadControls for ASP.NET AJAX Q2 2013\Bin35 

to my own project bin folder and added reference again.



The problem is that RadGrid is getting worse it does not even work for IE8 anymore.

When<telerik:GridButtonColumn ButtonType="LinkButton" DataTextField="type" UniqueName="type" CommandName="OnType"  ></telerik:GridButtonColumn> is clicked 

dataItem["document"].Text  keeps on getting a vaule of "&nbsp;".



Below are my ASPX file and code behind it.

  

Thank you for your help.
