PostBackOptions.AutoPostBack Property

 

Gets or sets a value that indicates whether the form will automatically post back to the server in response to a user action.

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

public bool AutoPostBack { get; set; }

Property Value

Type: System.Boolean

true if the form will automatically post back in response to a user action; otherwise, false. The default value is false.

You can use the AutoPostBack property to indicate that a Web Forms page should automatically post back to the server in response to a user action such as selecting an item from a drop-down list. The JavaScript setTimeout method is used with the _doPostBack method to ensure that the user action completes before the postback occurs.

The following code example shows the client-side script that is generated when the AutoPostBack property and the RequiresJavaScriptProtocol property are both set to true.

javascript:setTimeout('__doPostBack('__Page','')', 0)
