Populate DropDownGrid before Drawn

I want to populate a drop down grid (in this case, a databoundgrid), right before being displayed, each time the drop-down button is clicked. What event will tell me the grid is about to be drawn, and how do I get the cell that's requesting it from that event? Eric

HOWEVER, the VisibleChanged doesn't get called when the grid is becomming INvisible. So I still have no way of knowing when it's closing. Eric

FYI: On the subgrid, I've tried, with NO effect, the following event handlers on the sub-grid: ParentChanged, EnabledChanged, Deactivated None of these gets called from the subGrid, when the sub-grid is closing. Eric
