This will center the link's destination in the view:

Code
Select All
PointF destCenter = e.Link.Destination.GetCenter();
SizeF viewportSize = diagramView.ClientToDoc(
	diagramView.ClientRectangle).Size;
diagramView.ScrollTo(
	destCenter.X - viewportSize.Width / 2,
	destCenter.Y - viewportSize.Height / 2);


I hope that helps,
Stoyan

You will have to use the win32 SetCursorPos function, which takes screen coordinates:

[DllImport("user32.dll")]
static extern bool SetCursorPos(int X, int Y);

You can convert from diagram to screen coordinates by calling the view's DocToClient and PointToScreen methods.

I hope that helps,
Stoyan

Dear stoyan,

i have follow this code

PointF p=new PointF(destination.Bounds.X,destination.Bounds.Y);
            Point p1 = new Point(diagramView.DocToClient(p).X, diagramView.DocToClient(p).Y);
            Point p2=  PointToScreen(p1);
         

            SetCursorPos(p2.X, p2.Y);

Currently you are calling the form's PointToScreen method. You should call diagramView.PointToScreen(), since p1 is relative to the view:

Code
Select All
PointF p = destination.Bounds.Location;
Point p1 = diagramView.DocToClient(p);
Point p2 = diagramView.PointToScreen(p1);

SetCursorPos(p2.X, p2.Y);


I hope that helps,
Stoyan
