UpdatePanel.RenderMode Property

Gets or sets a value that indicates whether an UpdatePanel control's content is enclosed in an HTML <div> or <span> element.

Namespace:  System.Web.UI
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)
Public Property RenderMode As UpdatePanelRenderMode
<asp:UpdatePanel RenderMode="UpdatePanelRenderMode" />

Property Value

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

If the RenderMode property is set to Inline, the content of an UpdatePanel control is rendered inside an HTML <span> element. If the RenderMode property is set to Block, it is rendered inside an HTML <div> element.

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.
