Program errors working with OOPS ALV in a Tabstrip control

Hi Experts,

I am displaying an ALV grid in a Tabstrip control in dialog program and its getting displayed fine. However when I am presing any of the standard push buttons like sort, export etc., I am getting a pop up with icon 'STOP' and beside its mentioned 'Program errors'. Please let me now if there is any solution for this issue.

Thanks and Regards,

Praveen.
