public void ApplyStyle (System.Web.UI.WebControls.Style s);
member this.ApplyStyle : System.Web.UI.WebControls.Style -> unit
Public Sub ApplyStyle (s As Style)

範例

下列範例示範如何使用ApplyStyle方法,將樣式套用DataGrid至控制項。The following example demonstrates how to use the ApplyStyle method to apply a style to a DataGrid control.

注意

下列程式碼範例會使用單一檔案程式碼模型,如果直接複製到程式碼後置檔案中,則可能無法正確運作。The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. 此程式碼範例必須複製到具有 .aspx 副檔名的空白文字檔。This code sample must be copied into an empty text file that has an .aspx extension. 如需 Web Forms 程式碼模型的詳細資訊,請參閱ASP.NET Web Form 頁面程式碼模型For more information on the Web Forms code model, see ASP.NET Web Forms Page Code Model.
