RadGrid not showing headers and "no records" text

[Mark]

I am using a RadGrid with a DataSourceID that of a stored procedure.  When the stored procedure returns no rows, the grid is not showing up with the no records text and no headers.  However, when I removed the configuration DataSourceID="SqlDataSource10", the headers and no records text shows up as expected. I can't seem to get this to work so any help would be appreciated.

<telerik:RadGrid ID="rgExternalSensors" HeaderStyle-BorderStyle="None" HeaderStyle-BackColor="WhiteSmoke"

After an entire day of looking into this I finally found the issue. It was a bug in our store procedure. This is resolved.
