public virtual System.Web.UI.WebControls.ViewCollection Views { get; }
[<System.ComponentModel.Browsable(false)>]

屬性值

ViewCollection

ViewCollection，表示 View 控制項中 MultiView 控制項的集合。 預設為 null。

屬性
BrowsableAttribute PersistenceModeAttribute

範例

下列範例示範如何以程式設計方式將控制項 MultiView 加入 View 控制項。 建立每個 View 控制項之後， MultiView.Views.Add() 語法會用來將控制項新增 View 至 ViewCollection 控制項的 MultiView 集合。

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，可能無法正常運作。 此程式碼範例必須複製到副檔名為 .aspx 的空白文字檔中。 如需Web Form程式碼模型的詳細資訊，請參閱ASP.NET Web Forms頁碼模型。
