Sys.WebForms.EndRequestEventArgs Class

Used by the endRequest event of the Sys.WebForms.PageRequestManager class to pass argument information to event handlers. The endRequest event is raised just after the postback request has finished processing.

Namespace: Sys.WebForms

Inherits: Sys.EventArgs

Syntax

Constructors

Name	Description
EndRequestEventArgs Constructor	Initializes a new instance of the EndRequestEventArgs class.

Members

Member name	Description
dataItems Property	Gets a JSON data structure that contains data items that were registered by using the RegisterDataItem method of the ScriptManager class.
error Property	Gets the Error Object object.
errorHandled Property	Get or sets a value that indicates whether the error has been handled.
response Property	Gets a response object that is represented by the WebRequestExecutor class.

note

This class contains private members that support the client-script infrastructure and are not intended to be used directly from your code. Names of private members begin with an underscore ( _ ).

Remarks

An EndRequestEventArgs object is returned as a parameter in an event handler. You can use its error property to determine whether an error occurred and to obtain details about the error. You can also use the errorHandled property to determine whether the error has already been handled and to indicate that you have handled the error.

Example

The following example shows how to use two properties of the EndRequestEventArgs class. A Click event handler for a button in an UpdatePanel control throws an ArgumentException exception to simulate an unhandled exception. In the client script, a handler for the endRequest event of the PageRequestManager class checks the error property value. If the error is an unhandled server exception, the script sets the errorHandled property to true and displays an error message.
