Component can be hidden when page is first loaded by setting Hidden property to true. It can be displayed on demand by calling Show function of the client-side component object. For instance, a button click event can be used to show/hide the component.
By default, the component is rendered inline, i.e it's rendered exactly where the component tag is inserted. However it's also possible to display the component as a modal dialog by setting DisplayMode property to Window and setting WindowOptions sub-properties.
