Repeater.Items 屬性

定義

命名空間:
System.Web.UI.WebControls
組件:

控制區會得到一組 RepeaterItem 物件 Repeater 。

public:
 virtual property System::Web::UI::WebControls::RepeaterItemCollection ^ Items { System::Web::UI::WebControls::RepeaterItemCollection ^ get(); };
[System.ComponentModel.Browsable(false)]
public virtual System.Web.UI.WebControls.RepeaterItemCollection Items { get; }
[<System.ComponentModel.Browsable(false)>]
member this.Items : System.Web.UI.WebControls.RepeaterItemCollection
Public Overridable ReadOnly Property Items As RepeaterItemCollection

屬性值
