Hallo

I'm developping a custom forms designer using this base: http://msdn.microsoft.com/msdnmag/issues/06/03/DesignerHosting/default.aspx
I implemented the UndoEngine interface to use standart Undo() and Redo() commands. (using this source code:
http://www.geocities.com/balcanuc/TestUndoEngine.zip)

When I create a new form using "No Loader" or "Basic Designer Loader", the Undo/Redo works fine. However, if I use the "CodeDomDesignerLoader" the undo/redo works for adding and removing components but if I move or resize a component inside the form then I undo, the component gets selected but does not go back to it previous state. When I debugged the code I found the the UndoEngine is aware of the move/resize operation but undoUnit.Undo() has no effect.

Your help is highly appreciated.

(it's the old thread question from the id Wassim,but there is not solution yet)

anyone has idea or similar problem? thanks!

Hi Bell,

I have downloaded your TestUndoEngine project. I see you load a new form without loaders when the application starts. I don't think there's any difference when a form is loaded with any kind of loaders.

Could you please show us how you load the new form with BasicDesigner Loader and CodeDomDesignerLoader?

I look forward to your reply!

Sincerely,
Linda Liu
