Hi~
I am getting a lot of your help.
Thank you first.
What I want is to be able to edit the text of the node by double clicking after adding the control node to the diagram.
I expected to be able to edit text if I double click on node.
However, when I double clicked on the node, System.NullReferenceException occurred.
So I created the following event.
diagram1.EventSink.NodeDoubleClick += EventSink_NodeDoubleClick;
diagram1.EventSink.NodeClick += EventSink_NodeClick;
The NodeClick event worked fine, but the NodeDoubleClick event did not respond.
When both are used together, even if I double click on the node, the NodeClick event is triggered.
How can I edit text when double clicked on a node?
