Events in ALV Grid Control

Hi,

  I am working on ALV Grid Control. When the user clicks enter button on the keyboard the event DATA_CHANGED is triggered. I am actually collecting the data entered on the screen in the handler method of this event.

  Now, I want the same functionality with the Enter button on the SAP Screen (this button appears next to the Command Box in SAP Screen). Whenever I click the button in the SAP Screen, the DATA_CHANGED is not called.

How can I make the button on the screen work the same way as the Enter button on the keyboard.

This is very urgent requirement. Please help me.

Regards,

Vara
