    Found out the Issue and I will submit the bug report.  I guess in previous version if you had a <telerik:GridViewExpressionColumn> you could exclude the "Expression" parameter.  I had a column that did this because the expression was being built dynamically in the codebehind then added to the control.  All I had to do was set the expression parameter to something rather than excluding it.
    <telerik:GridViewExpressionColumn Expression=""/>

    In conclusion,the argument can be blank, but it cannot be null.

    After Upgrading from  Q32011 to Q12012 Telerik Controls and also the target Silverlight version of a project from 4 to 5 I get this following error on a page load. The page worked fine prior to the change.  Any help to point me in the direction of a resolution would be helpful. 

    Value cannot be null.

    Parameter name: body
