ASP.NET的GridView不显示

确定，所以我确定问题出在后面的代码，什么是不正确..ASP.NET的GridView不显示

DAL是一个类，从数据库中获取数据，和它的作品，肯定..后面

代码：

using DALLib; 
using System; 
using System.Collections.Generic; 
using System.Configuration; 
using System.Data; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 

namespace FinalProject 
{ 
    public partial class בתים : System.Web.UI.Page 
    { 
     protected void Page_Load(object sender, EventArgs e) 
     { 
      if (!IsPostBack) 
      { 
       MaxRooms.Attributes.Add("onChange", "return OnSelectedIndexChange()"); 
       MinRooms.Attributes.Add("onChange", "return OnSelectedIndexChange()"); 

       Cities.DataSource = (DataTable)Application["CitiesTable"]; 
       Cities.DataTextField = "Name"; 
       Cities.DataBind(); 
      } 

      DAL findHouses = new DAL(
       "SELECT * FROM Houses WHERE City='" + Cities.Text + "' AND Rooms BETWEEN '" + MinRooms.Text + "' AND '" + MaxRooms.Text + "'", 
       ConfigurationManager.AppSettings["ConnectionString"], 
       "Houses" 
       ); 

      Application.Lock(); 
      Application["SearchResultsTable"] = findHouses.GetTable(); 
      Application.UnLock(); 

     } 

     protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
     { 
      SearchResults.PageIndex = e.NewPageIndex; 
      BindHousesToGrid(); 
     } 

     private void BindHousesToGrid() 
     { 
      SearchResults.DataSource = (DataTable)Application["SearchResultsTable"]; 
      SearchResults.DataBind(); 
     } 

    } 
}

形式：

<div> 
    <asp:GridView ID="SearchResults" runat="server" CellPadding="4" GridLines="None" AutoGenerateColumns="False" ForeColor="#333333" AllowPaging="True"> 
     <AlternatingRowStyle BackColor="White"></AlternatingRowStyle> 
     <Columns> 
      <asp:BoundField DataField="Id" HeaderText="מספר נכס" /> 
      <asp:BoundField DataField="City" HeaderText="עיר" /> 
      <asp:BoundField DataField="Street" HeaderText="רחוב" /> 
      <asp:BoundField DataField="Rooms" HeaderText="חדרים" /> 
      <asp:BoundField DataField="size" HeaderText="גודל" /> 
      <asp:BoundField DataField="price" HeaderText="מחיר" /> 
     </Columns> 
     <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White"></FooterStyle> 

     <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White"></HeaderStyle> 

     <PagerStyle HorizontalAlign="Center" BackColor="#FFCC66" ForeColor="#333333"></PagerStyle> 

     <RowStyle BackColor="#FFFBD6" ForeColor="#333333"></RowStyle> 

     <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy"></SelectedRowStyle> 

     <SortedAscendingCellStyle BackColor="#FDF5AC"></SortedAscendingCellStyle> 

     <SortedAscendingHeaderStyle BackColor="#4D0000"></SortedAscendingHeaderStyle> 

     <SortedDescendingCellStyle BackColor="#FCF6C0"></SortedDescendingCellStyle> 

     <SortedDescendingHeaderStyle BackColor="#820000"></SortedDescendingHeaderStyle> 
    </asp:GridView> 
</div>

我的窗体上的按钮还没有做任何事情，但首先我希望gridview显示初始值，意味着整个数据库表.. 我做错了什么？

网格没有绑定到任何数据源。添加到Page_Load中：

BindHousesToGrid();

我还使用此代码内if(!IsPostBack) { }块，这样你就不会检索每一个回发相同的数据。
