Question

In a C# winforms app what is the normal way to persist the data on form that is opened by another form? I’d planned on just keeping it all on the form object but when the form is closed it seems the that form object is disposed. meaning I loose all the data.

I could wrap the form up in another object which takes all the data off it but that seems like a lot of work.

Is there a way to just hide the form when it is closed rather than disposing of it?

On closing a form is not Disposed. Generally this is how the data is managed.

  Result res;   using (MyForm form = new MyForm())   {       if(form.ShowDialog()== DialogResult.OK)        {          // In Myform, after the data collection is done, you can set  DialogResult=DialogResult.Ok and close form using form.Close();           res = form.Result; // expose forms data as result.                                     }   }   UserResult(res);
