EnableAjaxViewState Property (FlatDataBoundControl)

Gets sets ability to maintain view state of controls on page if their properties were modified while asynchronous postback of this control.

Syntax

Visual Basic

'Declaration
 
Public Property EnableAjaxViewState As Boolean

C#

public bool EnableAjaxViewState {get; set;}

Remarks

That property has effect only when asynchronous postback is triggered by this control. Those can be postbacks triggered by AutoPostBackFlags with value "Async", or internal postbacks such as sorting of grid.

If that property is disabled, then properties of any control on page modified while that async postback will be lost after a full postback. Value false will also reduce size of response stream. If that property is enabled, then in some applications the server exception related to EventValidation is possible. If it happens, then application should disable that property or set EnableEventValidation attribute of page to false.
