unhandled exception

I occasionally receive this  exception after changing the datasource object and performing sorting on various grid colums. This not not happening after specific change in the datasource but when happens my application is terminated with the following exception which is handled on the program.cs around the Application.Run(new FormMain());

 

Object reference not set to an instance of an object.
