If I want to split one ArrayCtrl so that I can scroll one part and leave another part as is, how would I implement that please? I am thinking about how in Excel you can keep some data visible at the top while scrolling down.

Thanks for any help or suggestions.

Actually I managed it by using two GridCtrl side by side using splitter. And on scroll I shift other control also. I wanted fixed columns.

FixedColGrid.sby.WhenAction = THISBACK ( Scroll );

void Scroll() {
int u1 = FixedColGrid.sby.Get();
ProcessGrid.sby.Set ( u1 );
}


Similar thing will be possible for vertical placement of two grids
using splitter.

Hope this may use useful.

Warm Regards

The last I needed that for ArrayCtrl, I did the same.

The keys is to use WhenScroll and WhenData callbacks to synchronize, something like

ArrayCtrl left, right;
left.WhenScroll = left.WhenSel = THISBACK(LeftToRight);
right.WhenScroll = right.WhenSel = THISBACK(RightToLeft);

void MyApp::LeftToRight()
{
   right.SetCursor(left.GetCursor());
   right.ScrollTo(left.GetScroll());
}
