I have a DataGrid (dg) with working event listeners on
populated cells (cellPress) and Headers (headerRelease). The
DataGrid is populated dymanically, and normally has a large
unpopulated area. I need to be able to detect a mouse click / mouse
up / mouse down in the unpopulated area. The best that I've been
able to get to work is the code above, but replacing the dg.OnPress
function takes over the cellPress and headerRelease events as well.
dg.onPress has no parameters (event=undefined) so I cannot write
code to re-direct to the other handlers within onPress.
