Disable Selecting of Nodes/Links

Is there any way to disable the selection of nodes/link and disable the edit funktion during the Behavior.DrawXXX (XXX=ShapeNodes,Links ... ) functions?
I want only Draw (and Add) new Nodes/Links to the diagram.
I change the Behavior to Behavior.Modify if i want to select (and modify) the nodes.

Handle the NodeSelecting and LinkSelecting validation events, and set e.Cancel = true.

I hope that helps,
Stoyan

Thanks, this works well, now i have another question:

If I change the behavior, all selected Items are deselected. But I want to "take" this selection in the new Behavior. Do I have to store the current selection, change the behavior and reset the selection? Or are there some other functions which are allowing to change the behavior without deselecting all Items?

Clearing the selection from the Behavior setter doesn't seem to make much sense, perhaps it's some remnant from our ActiveX control where it was necessary for some reason. Now this build won't clear it anymore:

I hope that helps,
