Assembly: System.Web (in system.web.dll)

The ClearChildState method clears all view-state and control-state information for child controls. It is equivalent to calling both the ClearChildViewState method and the ClearChildControlState method.

When recreating child controls of a Control object, use the ClearChildState 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 ClearChildState method is used to remove any state information that had been saved for the child controls.

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