QuantumGrid - Drag and drop

[Johanna Leimer]

Does anyone know how to find out where exactly at the target the user
dropped the dragged item?

Suppose I have a ListView with a couple of rows in it as the target. Now I
would like to find out on which row in the list view the user dropped the
dragged item so that I can react accordingly.

Any help is very much appreciated.

Many VCL component has the OnDragDrop event-handler that passes the
actual mouse X and Y coordinates relative to the target control. Almost
every item based control has some methods to find out the item from XY
coordinates. TListView has the GetItemAt,GetNearestItem methods that do
exactly what you want.

Thanks, that helped me a bit further although I couldn't solve my problem.
It works for a ListView but when I use a TcxGrid there ist no GetItemAt
method.

In the view of the cxGrid I can call GetHitTest(X,Y).HitTestCode to find out
whereabouts the drop was (e.g. htCell oder htHeader). But how do I find out
which cell (even row would be enough for me) the drop took place?

The SelectedRow or FocusedRow don't change during a Drag-and-Drop although
the rows where the mouse is over get highlighted. There must be a way to
find out. Any more ideas?
