Hi Klaudiusz,
Thanks for your update,
We suggest you to set node’s “Editstyle” property “AllowSelect”
to false to achieve your requirement. Please refer the below code snippet for
your reference.
[C#]
Syncfusion.Windows.Forms.Diagram.Ellipse ellip = new Syncfusion.Windows.Forms.Diagram.Ellipse(300, 200, 100, 70);
AddLabel(ellip, "Ellipse", Position.Center);
ellip.EditStyle.AllowMoveX = false;
ellip.EditStyle.AllowMoveY = false;
//AllowSelect indicating whether node can
be Selected or not
ellip.EditStyle.AllowSelect = false;
diagram1.Model.AppendChild(ellip);
Please try the sample and let us
know if you have any queries.
Regards,
Ashok Kumar
