I am using the 2008.1 version of radGrid, and am having a problem with one set of data that I am trying to display. The grid is bound to a dataset obtained from a stored procedure. The stored procedure contains a simple select statement, that, on occasion, will not return any data.
In this new version, instead of seeing the NoRecordsTemplate, the page crashes with stack dump below. I have other pages with the same setup that seem to work fine. This page also works as long as the SP doesn't return an empty recordset. (For clarification, the SP does indeed return an empty recordset. It doesn't try to return nothing.).
Thanks,
Joel

Hello Joel,
This looks like the problem we unfortunately introduced with the aggregates in ASP.NET 3.5 version of the Grid with an empty DataSource. It will be fixed shortly and the bug fix will be included in the next official update.
You can turn the linq expressions off for the time being. Please, set Grid's EnableLinqExpressions to false and let us know if further assistance is needed.

Well....changing EnableLinqExpressions to false definitely changes something. Now the grid ALWAYS throws an error! :-)
