Dear Stoyo,

       i am copying some nodes and want to paste the nodes on the cursor postion. but it is pasting different location. the code i am using is

            Point p = diagramView.PointToClient(Cursor.Position);
            PointF oldcurpos = diagramView.DocToClient(p);

            pasteDX = Convert.ToInt32(oldcurpos.X);
            pasteDY = Convert.ToInt32(oldcurpos.Y);
            
            diagramView.PasteFromClipboard(pasteDX, pasteDY, true);

The dx,dy parameters of PasteFromClipboard designate offset from the original position of the pasted items. If you need them pasted at a specific position, you will have to calculate that offset by subtracting the original Selection.Bounds.Location from the  paste location.

I hope that helps,
Stoyan

thanks Stoyan,

i have used the following code

            Point p = diagramView.PointToClient(Cursor.Position);
            PointF oldcurpos = diagramView.DocToClient(p);

            pasteDX = Convert.ToInt32(oldcurpos.X - diagram.Selection.Bounds.Location.X);
            pasteDY = Convert.ToInt32(oldcurpos.Y - diagram.Selection.Bounds.Location.Y);
            
            diagramView.PasteFromClipboard(pasteDX, pasteDY, true);

this code is working in the same file and the nodes are selected

1.  but i have unselected the node and paste. then it is pasting in some other position.

2.  if i paste in another file also it is pasting in some other position.

kindly help

Do not use the current selection position, but save Selection.Bounds before calling CopyToClipboard and then use the saved position to calculate offset when pasting.
