You can handle the EnterInplaceEditMode event to get a reference to the TextBox control used for editing, and then attach a KeyDown event handler to it to detect Shift+Enter.

I hope that helps,

It isn't, unless you implement inplace editing yourself by adding a DiagramNodeAdapter(RichTextBox) to the diagram, and remove it when done editing.

Hello, Stoyan.
I have the problem with UndoManager. I derived me node class from ShapeNode and customize it by some new properties such as number of inputs/outputs, show indexes of the anchor points, shadow properties: show shadow, shadow depth and shadow color and etc. And for undo/redo I use the ChangeItemCmd. But when I try to Undo shadow properties is not undo. What happens? Am I need to override ChangeItemCmd class as in the help file?

Thanks! I realize this by my derived class from Command and add it into sumcommands collection of the ChangeItemCmd. But later I try yuor method.
