ALV on Subscreen

[Former Member]

Hi,

i have an Problem with handle Events from ALV in an Subscreen.

I have create the eventhandle and have set it to my ALV on the subscreen. But the event doesn't raise.

Where have I to implement this handler? It can't be the same as in normal Screens. There it runs without any Problems.

Where are the differents?

Thanks,

Peter

Peter,

This is implemented similary to main screen's ALV. Actually there is no difference for the system whether AVL is embeded in main screen or a subscreen. The handler must be correctly set and that's it. Refer below program. It uses ALV in subscreen and the event handling works fine

          handle_double_click FOR EVENT double_click OF cl_gui_alv_grid
