expansion component and scrolling

Hi,

I am using version 8.3.

I have a listgrid with a custom expansion component. When I am opening the expansion in the grid by clicking on the expansion icon I would like to scroll the grid so that the complete expansion is visible (which is not the case when I am clicking on an row at the bottom of the list - then only the top of the expansion is visible).

My problem is that I could not find the event yet when the expansion is already drawn and the grid body resized to make the scrolling.

Thanks.
