Dialog problem using tabstrip & cl_gui_alv_grid

Question

Hi All,
     I have created a dialog program which has 2 tab strips. On first I am displaying data n a table control & on other tabstrip display same data using grid. Here to display data in grid I have used set_table_for_first_display of class cl_gui_alv_grid.
The data is displayed successfully. But when I select second tab and return to first tab it still shows the grid on first tab in front.
Kindly tell me what I am missing.
Regards,
Dilip

Have you attached a subscreen to tab T1 .
You will also have to use Call subscreen .
