This example illustrates how to use the client-side API of RadAjaxManager to implement a simple text editor.

The events used here are: OnRequestStart and OnResponseEnd.
The event handler functions for these are defined as follows: <ClientEvents OnResponseEnd="OnResponseEnd" OnRequestStart="OnRequestStart"></ClientEvents>

The OnRequestStart event fires just before the XmlHttpRequest is sent to the server. In this example it is used to disable controls on the form and displaying status information. Moreover, we are also using this event to prompt the user to cancel the AJAX request if he wishes to.

The OnResponseEnd event fires when the html on the page has been updated by Telerik RadAjax. We use it in this example to update status information and re-enable form controls to allow the user to continue work.
