I have a TextBox to which i bound a string, if i now edit the text manually i will be able to undo those changes via TextBox.Undo(), if however i change the string and the TextBox’s text is updated, i cannot undo those changes and the TextBox.CanUndo property will always be false.
I suppose this might have to do with the complete replacement of the text rather than a modification of it.
Any ideas on how i can get this to work?
OK, started to leave a comment and realized it was an answer 🙂
TextBox.Undo() is intended to undo a user’s interaction with the text box not a value change in the property it’s bound to. A change in the property the text box is bound to will just update the value of the TextBox, this is a different change than a user edit via focus/keyboard. If you need to Undo changes to your bound properties you probably need to investigate adding an Undo/Redo stack to your application.
