Deletes the view-state information for all the server control's child controls.
Assembly: System.Web (in System.Web.dll)
This method is commonly used when you override the DataBind method when developing templated data-bound server controls. If you do not call this method, child control view–state information can be written to a parent server control, only to be overridden when the data is bound.
When recreating child controls of a Control, use the method to clear child view state so that it does not get applied to the new controls inadvertently.
For more information about using this method, see How to: Create Templated ASP.NET User Controls.
