Hi,

Thank you for your interest in Essential Diagram.

If your intention is to move the symbols but avoid deleting it then it can be achieved by setting the EditStyle.AllowDelete property to false.

[C#]

//Avoids deletion of a node
Node.EditStyle.AllowDelete=false;

Please refer the sample in the below link which illustrates the above.

If I have misunderstood your requirement, could you please explain me in detail, so that I can work in depth and try to send a better solution?

Regards,
Melba
