C＃：重置面板中的控件（WinForms）

Question

What is a quick way to reset all the Controls inside a panel to their initial states (Compile-time state)? I have TextBoxes , RadioButtons , ComboBoxes , and CheckBoxes to reset. I'd like them to reset to the values when the program first ran. I'd like a solution that does not involve looping or recursion mainly because I don't want to reimplement the same thing over again when I start witha new project. I'm simply finding a set of methods to call that will do the job. Are there any?

Your controls have no compile time state, because state is a runtime concept.

I think you mean you want controls re-initialized to the state as shown on your property sheets. This state is applied by the generated code located in InitializeComponent , so to re-apply that state, you could just call it again.

The only problem is InitializeComponent also wires up events, and you probably don't want to do that twice. You could possibly work around this by deregistering all of your events before calling it, or by deduplicating the invocation list afterward (see this answer ).

I don't recommend any of this. The best approach would be to write your own method that sets the properties the way you want them, one by one. Sometimes ya gotta write code.
