  • 参考

定义

命名空间:
System.Web.UI
程序集:
System.Web.Extensions.dll

获取或设置一个值，该值指示 UpdatePanel 控件的内容是否包含在 HTML <div> 或 <span> 元素中。

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; }
member this.RenderMode : System.Web.UI.UpdatePanelRenderMode with get, set
Public Property RenderMode As UpdatePanelRenderMode

属性值

UpdatePanelRenderMode

UpdatePanelRenderMode 值之一。 默认值为 Block，以便面板内容包含在 HTML <div> 元素中。

示例

以下示例演示如何以声明方式设置 RenderMode 属性。 命名UpdatePanel1的UpdatePanel控件在 HTML <span> 元素中呈现。 RenderMode如果属性设置为Block该属性，则生成的段落将因呈现 HTML <div> 元素的方式而取消联接。
