Working with 2 grids

I have 2 grids, which are in a way linked.

There can be lots of data in the grids, though they always have the same rowcount.

What I want my app to do, is when I go down enough rows that the scrollbar starts to move (or the TopLeftChanged event occurs), that BOTH my stringgrids uses the scroll bar so I can see the applicable data in both grids.

Just changing the selection on the other grids doesn't work.

This is what I tried

PHP Code:


		
			
 TGridRect Temp = ((TStringGrid *)Sender)->Selection;

  Grid1->Selection = Temp;

  Grid1->SetFocus();

  Grid2->Selection = Temp;

  Grid2->SetFocus();

  ((TStringGrid *)Sender)->SetFocus();

this doesn't work, as it is important that both the grids have the same visibility, but not really the same active cell (though not a bad thing).

Can anyone help me?

Something like this perhaps?

Code:

Grid2->TopRow = Grid1->TopRow;

The Delphi 6 equivalent of the above works for me, so I think it should work for you too.

Just to add on what Scorpions4ever brought foreward;

Draw1->LeftCol = Draw2->LeftCol

* if you want to keep the horizontal scrollbars also sychronized.

Thanks!!

Haven't tried it though, but I am sure it'll work. Eventually I opted to display everything on one grid... it's not the same, as the data aren't *that* related, but I just changed the 'visible' property of the old grids to false for now, so it's not hard going back to the old way.
