public:
 property System::Web::UI::UpdatePanelRenderMode RenderMode { System::Web::UI::UpdatePanelRenderMode get(); void set(System::Web::UI::UpdatePanelRenderMode value); };
public System.Web.UI.UpdatePanelRenderMode RenderMode { get; set; }

Public Property RenderMode As UpdatePanelRenderMode

Property Value

UpdatePanelRenderMode

One of the UpdatePanelRenderMode values. The default is Block so that the content of the panel is enclosed in an HTML <div> element.

Examples

The following example shows how to set the RenderMode property declaratively. The UpdatePanel control named UpdatePanel1 is rendered in an HTML <span> element. If the RenderMode property were set to Block, the resulting paragraph would appear disjointed because of the way in which the HTML <div> element is rendered.
