I'm looking for a way to drag-and-drop a row from a xamDataGrid to another component (i.e. treeView)

It seems like PreviewDragLeave, DragDrop.DrageLeave, DragLeave events are not really fired.

I've tried also using the MouseMove event:

void myGrid_MouseMove(object sender,MouseEventArgs e) 
{
    if(!_isDragging && e.LeftButton == MouseButtonState.Pressed)
    {
        _isDragging = true;

        var row = myGrid....;
        DragDrop.DoDragDrop(myGrid,treeView.row,DragDropEffects.Move);
    }
}

to no avail. Any ideas ?
