的ObjectDataSource的Select方法更新按鈕

我有與ObjectDataSource控件DataList控件之前調用，問題是，當我調用Update方法，數據列表的selectmethod的更新方法，它在結果犯規顯示了更新的數據列表之前執行，我必須F5查看更新的結果，下面是代碼：的ObjectDataSource的Select方法更新按鈕

AspView

<asp:DataList ID="CustomersDefaultPaging" runat="server" Width="100%" 
    RepeatColumns="1" EnableViewState="False" 
    DataSourceID="CustomersDefaultPagingDataSource" DataKeyField="Id"> 
    <ItemTemplate>.....</ItemTemplate> 
    <asp:ObjectDataSource ID="CustomersDefaultPagingDataSource" runat="server" 
     OldValuesParameterFormatString="original_{0}" SelectMethod="GetCustomersAsPagedDataSource" 
     TypeName="mobilecustomers" 
    OnSelected="CustomersDefaultPagingDataSource_Selected">

代碼隱藏

 protected void CustomersDefaultPagingDataSource_Selected(object sender, ObjectDataSourceStatusEventArgs e) 
{ 
    // Reference the PagedDataSource bound to the DataList 
    PagedDataSource pagedData = (PagedDataSource)e.ReturnValue; 

    // Remember the total number of records being paged through across postbacks 
    TotalRowCount = pagedData.DataSourceCount; 

    // Configure the paging interface based on the data in the PagedDataSource 
    FirstPage.Enabled = !pagedData.IsFirstPage; 
    PrevPage.Enabled = !pagedData.IsFirstPage; 
    NextPage.Enabled = !pagedData.IsLastPage; 
    LastPage.Enabled = !pagedData.IsLastPage; 

    // Display the current page being viewed... 
    CurrentPageNumber.Text = string.Format("You are viewing page {0} of {1}...", PageIndex + 1, PageCount); 
} 

    protected void btnSave_Click(object sender, EventArgs e) 
{ 
    foreach (DataListItem item in CustomersDefaultPaging.Items) 
    { 
     customers.UpdateCustomerAddress(.........); 


    } 
}

DataAcess

 static public DataTable GetAllCustomers() 
    { 

    string sql = "Select * from [Customers] where [Upgrade] = 0"; 
    SqlDataAdapter da = new SqlDataAdapter(sql, ConnectionString); 
    DataTable dt = new DataTable(); 
    da.Fill(dt); 
    return dt; 
    } 

     public PagedDataSource GetCustomersAsPagedDataSource(string sortExpression, int pageIndex, int pageSize) 
{ 

    DataTable dt = new DataTable(); 
    dt = GetAllCustomers(); 
    dt.DefaultView.Sort = sortExpression; 
    // Limit the results through a PagedDataSource 
    PagedDataSource pagedData = new PagedDataSource(); 
    pagedData.DataSource = dt.DefaultView; 
    //pagedData.DataBind(); 
    pagedData.AllowPaging = true; 
    pagedData.CurrentPageIndex = pageIndex; 
    pagedData.PageSize = pageSize; 
    return pagedData; 
}

上更新單擊DataList控件應該只顯示客戶，其升級值爲0，Curretly當我更新字段爲0，它更新SQL數據庫，但它在DataList我必須刷新它以犯規節目查看更新。

顯然，DataList沒有做它自己的重新綁定。我不知道這是否會工作，但關於掛接到DataList控件Updated事件，迫使電網綁定有什麼。可以幫助嗎？

從我讀過的GridView控制起到更好了很多與ObjectDataSource。這是我的話我可能會換出DataList爲GridView，看看有沒有什麼幫助。或者至少進行一些快速測試並看看。

都有點含糊誠然
