How to register for the Drop event in the Details grid of a Master/Details grid

[Stefan Cuypers]

I'm trying to register for the Drop event in a master/details grid to be warned when a row is dropped on a detail grid.

If I try to do this as follows:

            dataGrid.RowDragDropController.Drop += OnRowDropMaster;

            grdSubOrders.RowDragDropController.Drop += OnRowDropChild;

then OnRowDropMaster is called when dropping on a master row, but OnRowDropChild is never called.

(dataGrid is the main grid, grdSubOrders is the Details view grid definition)

See the example attached.

If you run it, then expand the first 2 lines and then drag a subrecord on the second line to the subrecords on the first line you'll see that the record moves on the grids, but the drop event is never called.

Root Cause Details:

We missed the properties of the RowDragDropController class while copying from ParentDataGrid to DetailsViewDataGrid. This issue will now be resolved by copying the RowDragDropController class to the DetailsViewDataGrid.
