The Infamous "Clear All Controls" , Generics Style
In the ASP.NET world, its invaluable to be able to clear all controls on a form, or disable all controls, or even reset the controls to a default state. I am going to show you an awesome way to do it, Generics Style. We will be building this using a method that takes in a Generic Type of Control, and a /// /// Excellent Method to abstract and add into the Helper classes : Using Generics /// /// private void ManageControls (Control parent, Func del) where Gen : Control { foreach (Gen c in parent.Controls) { if (c is Gen) { del.Invoke(c); if (((Control)c).HasControls()) ManageControls (((Control)c), del); } } } ManageControls (parent, x => x.Items.Clear()); ManageControls (parent, x => x.Text = "");
