Restricting tool activity

[John Previn Kumar]

Can we make a tool inactive in certain place of the diagram? I need to be able to draw circles on upper left corner of the diagram control. for eg) If diagram control is 100X100 pixels size, I need to restrict drawing of circles only on top left 50X50 pixels.

Hi JVM,

Thanks for using Syncfusion products and sorry for the delay in getting back to you.

You can achieve your requirement by aborting the drawing tool. Here is the code snippet for your reference.

[C#]
diagram1.MouseMove += new System.Windows.Forms.MouseEventHandler(this.diagram1_MouseMove);
private void diagram1_MouseMove(object sender, MouseEventArgs e)
        {
            EllipseTool tool = diagram1.Controller.ActiveTool as EllipseTool;
            if (tool != null)
            {
                PointF curPt = diagram1.Controller.ConvertToModelCoordinates(e.Location);
                if (curPt.X > 50 || curPt.Y > 50)
                {
                    tool.Abort();
                    diagram1.Refresh();
                }
            }
        }

Please let me know if you have any concerns.
