Deletes the view-state and control-state information for all the server control's child controls.
Assembly: System.Web (in System.Web.dll)
When recreating child controls of a Control object, use the method to clear child state so that it does not get applied to the new controls inadvertently.
The following code example demonstrates how to override the OnDataBinding method for a templated data-bound control. If the data source that the control binds to is populated, the control's ControlCollection collection is emptied using the Clear method, and the method is used to remove any state information that had been saved for the child controls.
