Call update() on the client side to immediately update the calendar after changing the properties.

Note that the server-side rendering event handlers (such as BeforeEventRenderBeforeCellRenderBeforeTimeHeaderRenderBeforeResHeaderRender render) will not be called. For a server-side assisted update, please use CommandCallBack.

Changing a Date (Example)

dps.startDate = "2013-05-01";
dps.update();

Remember to have the events preloaded or to load them manually using events.add().
