System.Web 2.0.0.0 System.Object

The class allows controls to emit client-side script that initiates a postback event. The class also provides a reference to the control that initiated the postback event through the property. The postback event is created based on the options specified in the object passed in to the method.

Normally, a postback to the server is initiated by elements such as a Submit button or an Image button. However, by emitting client-side JavaScript, different controls can initiate a postback event.

Specifies how client-side JavaScript is generated to initiate a postback event.
