  • 參考

定義

命名空間:
System.Web.UI.HtmlControls
組件:
System.Web.dll

轉譯 HtmlTable 控制項的結束標記。

protected:
 override void RenderEndTag(System::Web::UI::HtmlTextWriter ^ writer);
protected override void RenderEndTag (System.Web.UI.HtmlTextWriter writer);
override this.RenderEndTag : System.Web.UI.HtmlTextWriter -> unit
Protected Overrides Sub RenderEndTag (writer As HtmlTextWriter)

參數

writer
HtmlTextWriter

HtmlTextWriter 接收轉譯的內容。

範例

下列程式碼範例示範如何覆寫 RenderEndTag 方法，使其一律會在自訂 HtmlTable 伺服器控制項中寫入結束標記和新行。

備註

方法 RenderEndTag 會在呼叫基類 HtmlContainerControl.RenderEndTag 的 方法之後提供額外的格式。 其他格式設定可讓控制項的 HtmlTable 轉譯 HTML 更容易閱讀，方法是在結尾 <table> 標記之後插入一行傳回。

方法 RenderChildren 主要是由控制項開發人員使用，以擴充控制項的功能 HtmlTable 。
