Is there a way of getting a reference to the UltraGrid to which an UltraGridRow belongs?

Here's what I am doing: I have a pre-existing ultraGrid_DragDrop event-handling delegate.

All grids use the same delegate because they all do the same thing.

But I must now add code to prevent a drag-drop operation ON THE SAME GRID. Different grid is OK.

I am trying to do this by comparing the dropGrid to the sourceGrid and making sure they are not the same.

Here's how far I got:

I get the drop grid from the sender object.

UltraGrid dropGrid = sender as UltraGrid;

And I have a sourceRow from the source grid by using the DragEventArgs e.

SelectedRowsCollection sourceRows = e.Data.GetData(typeof(SelectedRowsCollection)) as SelectedRowsCollection;

I know there is at least one row inside the collection, so:

UltraGridRow sourceRow = sourceRows[0];

But how do I now get the sourceGrid from the sourceRow? Is there a way?
