exception of type 'system.outofmemoryexception' was thrown.

Hi,

It seems like "exception of type 'system.outofmemoryexception' was thrown" is a common error that people are having using the RadGrid; however, I can not find any real solution that works on the forum.  My dataset contains 3.5 million records for 80 rows of data.

Regards,
