ControlCollection::Clear Method

Removes all controls from the current server control's ControlCollection object.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

public:
virtual void Clear()

Use this method to empty a custom control's ControlCollection when you override the Control::CreateChildControls and DataBind methods. Do this when you develop composite, templated controls or templated data-bound controls.

The following code example demonstrates overriding the Control::CreateChildControls method, and using the Clear method to delete all child controls previously in the ControlCollection object. In this case, you must do this so that outdated objects in your control's ControlCollection are not displayed inappropriately.

No code example is currently available or this language may not be supported.
