Hi!  From other posts and just messing around, I'm very close to making this work properly.  However I'm running into a couple of issues that I can't seem to clear up.

Essentially I have two flowchart controls on one form.  When one is disabled, boxes on that control can be dragged and dropped on the second flowchart.

Here's the pertinent code:

	  private void flowChart2_DragOver(object sender, DragEventArgs e)
	  {
		e.Effect = DragDropEffects.Copy;
	  }

	  private void flowChart2_DragDrop(object sender, DragEventArgs e)
	  {
		PointF pF = flowChart2.ClientToDoc(new Point(e.X, e.Y));

		if (e.Data.GetDataPresent(typeof(Box)))
		{
		    Box tb = (Box)e.Data.GetData(typeof(Box));
		    //tb.Move(pF.X, pF.Y);
		    flowChart2.Objects.Add(tb);

		    flowChart2.Refresh();
		}
	  }

	  private void flowChart1_MouseDown(object sender, MouseEventArgs e)
	  {
		if (flowChart1.Behavior == BehaviorType.DoNothing)
		{
		    PointF pF = flowChart1.ClientToDoc(new Point(e.X, e.Y));
		    Box b = flowChart1.GetBoxAt(pF);

		    if (b == null) return;
		    DoDragDrop(b, DragDropEffects.Copy);
		}
	  } 

Here are my problems:

1.)  If there are arrows connected to the original box, they are also copied, but are only visible when the box in the second FC is selected.  Also, the arrow isn't selectable.  I DON'T want any connected arrows to transfer - only the box.

2.)  I can't get the box to drop where the users mouse is. The //tb.Move(pF.X, pF.Y); was my attempt at this, but it offset the placement of the shape in the second FC, and deleted it from the top FC!!

3.)  If one of the "drag/dropped" boxes in the second FC is selected and moved, the application crashes.


Can you help me with this??

Thanks in advance,
Blaze

Excellent - Thank you!  Your suggestions fixed problems 1 & 2 perfectly.  Now the boxes will drag/drop without arrows and the application doesn't crash when I move the dropped boxes.

I'm still having trouble with the position of the dropped box though.  Here is the DragDrop method:

	  private void flowChart2_DragDrop(object sender, DragEventArgs e)
	  {
		PointF pF = flowChart2.ClientToDoc(new Point(e.X, e.Y));

		if (e.Data.GetDataPresent(typeof(Box)))
		{
		    Box tb = (Box)e.Data.GetData(typeof(Box));
		    Box b = new Box(tb);
		    b.Move(pF.X, pF.Y);

		    flowChart2.Add(b);
		    label1.BackColor = Color.Red;
		    flowChart2.Refresh();
		}
	  } 

The dropped box ends up shifted quite a bit down and slightly to the right of where it's dropped.  If I comment out the "b.move(pF.X, pF.Y)" line, then the box is dropped in the same location that the original was (but on the second flowchart), regardless of where the mouse is.

What am I doing incorrectly?  By the way, both flowcharts are set up with the exact same properties.

Thanks again,
Blaze

Great, thank you.  Sorry about the redundant question - I didn't look carefully enough at your advice from your first reply.

Thanks again,
Blaze
