Provides properties, methods, and events for client-side programming of the ReportViewer control.
An instance of this class is created by the ReportViewer control. To access the handle to this instance, use the Sys.Application $find Method.
Depending on the state of the ReportViewer server control, accessing the methods and properties of the client side API may cause an exception. For example, When the Web page or the ReportViewer server control is performing a postback, accessing any of the methods or properties will cause an exception with the message: "The report or page is being updated. Please wait for the current action to complete."
When the Web page or the ReportViewer server control is not performing a postback, a set of methods require that a report is loaded. If no report is loaded, invoking those methods will cause an exception with the message: "The operation cannot be performed because there is no report loaded." See below for the applicable methods.
Handling Property Change Events
If you want to be notified when a property is changed, register an event handler with the Sys.Component.propertyChanged Event. This event is part of the ReportViewer instance's base class, the Sys.Component Class. For example:
<script language="JavaScript">
function propertyChangedHandler(sender, e)
{
alert("prop changed");
}
var rViewer = $find(viewerId);
rViewer.add_propertyChanged(propertyChangedHandler);</script>
