Vertical row scrolling using the Up Arrow or Down Arrow key doesn't fire the vertical grid's OnTopRowIndexChanged event

created 10 years ago (modified 10 years ago)

Hi,

I am trying to use the TcxDBVerticalGrid.OnTopRowIndexChanged event to synchronize 3 TcxDBVerticalGrid controls.
It works fine if I use the mouse to move the scroll bar or if I use the mouse wheel.

If I use the up/down keys this event is not fired.

Can you please confirm this?  And if applicable, provide me with a solution?

Thanks.

Luis

        Hello Luis,

        The issue is not investigated yet. Meanwhile, I suggest that you use the OnLayoutChanged event as it is demonstrated in the attached project to call custom code on changing the TopVisibleRowIndex property.
