property bool AutoPostBack { bool get(); void set(bool value); };
public bool AutoPostBack { get; set; }
member this.AutoPostBack : bool with get, set
Public Property AutoPostBack As Boolean
Property Value
true
if the form will automatically post back in response to a user action; otherwise, false
. The default value is false
.
Examples
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)
javascript:setTimeout('__doPostBack('__Page','')', 0)
Remarks
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.
