Listview未在asp.net中顯示

Question

我試圖在asp.net中實現listview。但我無法得到輸出。我犯了我不知道的錯誤。請幫助我。

我的模型

ASPX

<asp:ListView ID="ListView1" runat="server"> 
      <ItemTemplate> 
       <div> 
       <asp:Table runat="server" > 
        <asp:TableRow> 
         <asp:TableCell Width="40%"> 
          <asp:Label ID="Label17" runat="server" Font-Bold="true" Font-Size="Medium" Text='<%#Eval("RoomType") %>'></asp:Label> 
         </asp:TableCell> 
         <asp:TableCell Width="20%"> 
          <asp:Button ID="Button1" runat="server" Text="Search" /> 
         </asp:TableCell> 
        </asp:TableRow> 
        <asp:TableRow> 
         <asp:TableCell ColumnSpan="2"> 
          <asp:Label ID="Label18" runat="server" Font-Bold="true" Font-Size="Medium" Text='<%#Eval("Description") %>'></asp:Label> 
         </asp:TableCell> 
        </asp:TableRow> 
       </asp:Table> 
       </div> 
      </ItemTemplate> 
     </asp:ListView> 

C＃

 public class Place 
      { 
       public string RoomType { get; set; } 

       public string Description { get; set; } 
      } 

      List<Place> items = new List<Place>(); 
         items.Add(new Place() { RoomType = "RoomType1", Description= "RoomType Description"}); 
         items.Add(new Place() { RoomType = "RoomType2", Description = "RoomType Description" }); 
         items.Add(new Place() { RoomType = "RoomType3", Description = "RoomType Description" }); 

    ListView1.DataSource = items; 

使用Break point進行檢查時，我發現項目列表中包含項目。但我不能進入我的頁面。

Answer 1

設置列表視圖的數據源，並嘗試下面的代碼

protected void Page_Load(object sender, EventArgs e) 
     { 
      List<Place> items = new List<Place>(); 
      items.Add(new Place() { RoomType = "RoomType1", Description = "RoomType Description" }); 
      items.Add(new Place() { RoomType = "RoomType2", Description = "RoomType Description" }); 
      items.Add(new Place() { RoomType = "RoomType3", Description = "RoomType Description" }); 
      this.ListView1.DataSource = items; 
      this.ListView1.DataBind(); 
     } 

Answer 2

我沒有看到任何錯誤。你可以通過將它們寫入控制檯來檢查你的列表嗎？

Console.WriteLine(); 
     foreach (Place item in items) 
     { 
      Console.WriteLine(item); 
     } 

請添加一個foreach函數來查看。
