Control::IsTrackingViewState Property
Gets a value that indicates whether the server control is saving changes to its view state.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System::Booleantrue if the control is marked to save its state; otherwise, false.
For a sample custom server control that uses this property, see Templated Server Control Example
The following example overrides the DataBind method in a custom ASP.NET server control. It begins by calling the base OnDataBinding method and then uses the ControlCollection object. ControlCollection::Clear method to delete all the child controls and the ClearChildViewState method to delete any saved view-state settings for those child controls. Finally, the ChildControlsCreated property is set to true. The control then uses the IsTrackingViewState property to determine whether view-state change tracking is enabled for the control. If it is not enabled, the TrackViewState method is called.
