DataPager.SaveViewState Method

Saves any changes to an DataPager control's view-state that have occurred since the time the page was posted back to the server.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)
protected override Object SaveViewState()

Return Value

Type: System.Object
Returns the DataPager control's current view state. If there is no view state associated with the control, this method returns null.

View state is the accumulation of the values of a server control's properties. These values are automatically put in the server control's ViewState property, which is an instance of the StateBag class. This property's value is then persisted to a string object after the save-state stage of the server control life cycle. For more information, see ASP.NET State Management Overview.

When view state is saved, this string object is sent to the browser as a variable that is stored in a hidden element in the page. When you create custom server controls, you can improve efficiency by overriding this method and modifying the server control's ViewState property. For more information, see ASP.NET State Management Overview.

NoteNote

This method is primarily used by control developers to extend the DataPager control.
