I have a simple form containing a main view and also some text boxes and an “add” button that I use for adding data that is displayed in the main view (and stored in a text file). What I want to do is to add a little button that will toggle hiding/showing of the adding controls. Such button usually is a small square containing two arrowheads pointing up/down depending on the state. How do I do that?
(I’m sorry for the terrible title, but I don’t know the proper name for this. Could anyone tell me?)
I don’t think there’s something built-in in WinForms for that. When I needed to do something similar, I just changed the Height of the form…
