Does Form.Dispose() call controls inside's Dispose()?

is there a way to do this?

Answer 1

Both the Panel and the Form class have a Controls collection property, which has a Clear() method…

MyPanel.Controls.Clear(); 

or

MyForm.Controls.Clear();

But Clear() doesn’t call dispose() (All it does is remove he control from the collection), so what you need to do is

   List<Control> ctrls = new List<Control>(MyPanel.Controls);
   MyPanel.Controls.Clear();  
   foreach(Control c in ctrls )
      c.Dispose();

You need to create a separate list of the references because Dispose also will remove the control from the collection, changing the index and messing up the foreach…
