Hi Stoyan,

On mouse click over the diagram, I want to delete active node.This node is a simple ShapeNode.
How I can do this?

Thanks,
Anshul

If you want to delete the clicked node, do this from the NodeClicked event handler:

diagram.Items.Remove(e.Node);

or to delete the so-called active item from the Diagram.Clicked handler:

diagram.Items.Remove(diagram.ActiveItem);

I hope that helps,
Stoyan

Ok, the selection is cleared when you click on the diagram. You could handle the NodeActivated event and save a reference to the last active node in some variable of the form. You might as well call diagram.Nodes.Remove(e.Node) from NodeDeactivated, but NodeDeactivated might be raised in other situations too, and not only when clicking on the diagram.

I hope that helps,
Stoyan
