我沒有得到任何錯誤，我現在最大的問題是讓我的查詢工作。我有一個查詢完全給我我需要的東西，並且該查詢目前在我的代碼中，但它在C＃中不起作用。以下是我的代碼。

HTML

<div class="Demo"> 
    <h1>Tree Demo</h1> 
    <div class="tree well"> 
     <ul> 
      <li><span>ServerName</span> 
      <ul> 
       <asp:Repeater ID="rpDatabasesParent" runat="server" OnItemDataBound="loadTables"> 
        <ItemTemplate> 
         <li><span><%# Eval("Name") %></span> 
          <ul> 
           <h3>Tables</h3> 
           <asp:Repeater ID="rpTablesChild" runat="server" OnItemDataBound="loadTables"> 
            <ItemTemplate> 
             <li><span><%# Eval("Tables") %></span></li> 
            </ItemTemplate> 
           </asp:Repeater> 
          </ul> 
         </li> 
        </ItemTemplate> 
       </asp:Repeater> 
      </ul> 
      </li> 
     </ul> 
    </div> 
</div> 

C＃

public void testConnection()

      rpDatabasesParent.DataBind();
