OnAjaxRequest
The AjaxRequest event occurs when triggered by the client-side ajaxRequest() function or the server-side RaisePostBackEvent() method. The event can not be cancelled. The AjaxRequest event handler receives a single string argument.
The example below demonstrates AjaxRequest triggered from both the client and server. An a HTML input button and a standard ASP.NET button are defined in the example. The HTML input button triggers a function that calls the client-side ajaxRequest(). The ASP.NET button triggers a server-side OnClick event that in turn calls the RaisePostBackEvent() method.
