Public Enumeration UpdatePanelRenderMode

Member nameDescription
BlockSpecifies that the content of the UpdatePanel control is rendered inside an HTML <div> element.
InlineSpecifies that the content of the UpdatePanel control is rendered inside an HTML <span> element.

The UpdatePanelRenderMode enumeration defines which HTML elements to use to enclose the content of the UpdatePanel control. The RenderMode property must be one of the values of the UpdatePanelRenderMode enumeration. The content of an UpdatePanel control can be rendered inside either an HTML <div> element or a <span> element.

The default RenderMode property value is Block.

The following example shows how to declaratively set the RenderMode property of an UpdatePanel control to Inline. The UpdatePanel control contains a string that represents the number of postbacks from the page. The contents are rendered inline with the surrounding text.
