I have drag drop to FlowChart working fine, but now my users also want to have drag drop to another component from FlowChart.

I searched the forum and I have tried the following:

private void flowChart_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
        {

            if ((ModifierKeys & Keys.Shift) != 0)
            {
                PointF mousePosition = diagramView.ClientToDoc(e.Location);
                ShapeNode sn = flowChart.GetNodeAt(mousePosition) as ShapeNode;
                if (sn != null)
                {
                    DiagramNode node = sn.Tag as DiagramNode;
                    if (node != null)
                    {
                        if (flowChart.Interaction != null)
                            flowChart.Interaction.CancelNow();
diagramView.DoDragDrop(Commands.GetDragDropDataObject(node.BusinessObject), DragDropEffects.All | DragDropEffects.Link);
                    }
                }
            }

 

It works (I can drag and drop to another component) but the current interaction sin't cancelled (always null in the code above) and when I realeased the mouse teh rubber band selection rectangle is drawn from the point that was clicked to the coordinates where the mouse was released!

I'm using FlowChart with diagramView.Behavior = Behavior.Modify; I have tried to set it to Behaviour DoNoting in teh handler above , but that didn't helped.

Any tip is welcomed

Thanks, it works now!
