Your text change will always raise a new TextChanged event - the only way to prevent it being actioned is to "unhook" the event handler, change the text and then re-hook the handler - which is a nasty way to do things. Instead, I would set up a class level bool which you test at the top of the event handler: if it is true, ignore the handler and just set it false. If it is false, contiunue with the handler, and set it true just before you change the Text property.
