DataControlField.ViewState Property

Gets a dictionary of state information that allows you to save and restore the view state of a DataControlField object across multiple requests for the same page.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

protected StateBag ViewState { get; }

Property Value

Type: System.Web.UI.StateBag
An instance of StateBag that contains the DataControlField view-state information.

A data control field's view state is the accumulation of all its property values. To preserve these values across HTTP requests, ASP.NET server controls use this property, which is an instance of the StateBag class, to store the property values. The values are then passed as a variable to an HTML hidden input element when subsequent requests are processed. For more information about saving server control view state, see ASP.NET View State Overview.

View state is enabled for all server controls by default, but there are circumstances when you will want to disable it. For more information, see ASP.NET Performance Overview.

For more information about dictionaries and how to use them, see Collections and Data Structures.
