Gets a value indicating whether view state is enabled for this control.
Assembly: System.Web (in System.Web.dll)
View state can be enabled at the page, container, or control level. When view state is disabled at the page or container level, view state is disabled for all controls contained by the page or container. The property indicates whether view state is enabled by pages, containers, or controls.
It is possible for the EnableViewState property and the property to be different. For example, if the Page containing the control has view state disabled, the EnableViewState property can be true while the property is false.Notes to Inheritors
Page developers will set the EnableViewState property and the ViewStateMode property to indicate whether they are using view state with your control. Use the property and the ViewStateMode property in your code to determine whether view state is enabled for your control and for all containers.
