Hello,

After upgrading the binaries to 2008 Q2, My radgrids with GridCalculatedColumns are getting "Specified cast is not valid." exception.

I'm binding the grid from code behind by creating a dynamic class using LINQ.

Below is my code for GridCalculatedColumn

<telerik:GridCalculatedColumn Aggregate="Sum" DataFields="Lines" DataType="System.Int32" Expression="{0}"></telerik:GridCalculatedColumn>

1 Answer, 1 is accepted

As a silly question, I assume that the data being returned from your query is all intergers? Otherwise, it will cause the cast to be invalid. Have you tried Data.Type="System.Double" just to see if it runs?

Thanks for listening!
