Removes all controls from the collection.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You can use the method to remove the entire collection of controls from a parent control.
Calling the method does not remove control handles from memory. You must explicitly call the Dispose method to avoid memory leaks.
When overriding in a derived class, be sure to call the base class's method to ensure that all the controls are removed from the collection.
The following code example removes all the Control objects in the Control.ControlCollection of the derived class Panel. The example requires that you have created a Panel, a Button, and at least one other control on a Form. The other controls are added to the Panel control, and the Panel added to the Form. When the button is clicked, all the controls contained in the panel are removed from the Control.ControlCollection.
