ControlAdapter::OnPreRender Method
Overrides the OnPreRender method for the associated control.
Assembly: System.Web (in System.Web.dll)
If there is an adapter attached to a Control object and the OnPreRender method is overridden, the override method is called instead of the Control::OnPreRender method.
Override the OnPreRender method to perform target-specific processing in the PreRender stage of the control lifecycle. Typically, these are functions that immediately precede rendering of the control output.
Notes to InheritorsWhen you inherit from the ControlAdapter class and the adapter overrides the OnPreRender method, the adapter must call the corresponding base class method, which in turn calls the Control::OnPreRender method. If the Control::OnPreRender method is not called, the Control::PreRender event will not be raised.
