ASP.NET DetailsView在插入后返回空白

我有两个页面：第一个是绑定到DataSet的gridview，第二个具有绑定到DataSet的DetailsView，用于编辑和插入。ASP.NET DetailsView在插入后返回空白

一旦插入DetailsView页面，我想重定向到GridView页面。

if (Request.QueryString["Id"] == null) 
{ 
    //prevPage = Request.UrlReferrer.ToString(); 
    if (!IsPostBack) 
    { 
     DetailsView1.ChangeMode(DetailsViewMode.Insert); 
    }

详细信息页面允许正确插入新记录，但在保存之后返回空白页;我如何获得返回到更新的GridView页面？

我试图使用DetailsView的ItemInserted事件，但它根本不会触发。

更新：

的建议我添加以下代码：

protected void DetailsView1_ItemInserted(object sender, DetailsViewInsertedEventArgs e) 
{ 
    Response.Redirect("ms_Ticket.aspx"); 
}

（与ms_Ticket是在GridView页面），但插入继续返回空白DetailsView控件。

更新：

这里的详细信息页面的代码隐藏：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 

namespace Rise_cs.Ticket 
{ 
    public partial class WebForm4 : System.Web.UI.Page 
    { 
     static string prevPage = String.Empty; 

     protected void Page_Load(object sender, EventArgs e) 
     { 

      if (!IsPostBack) 
      { 
       if (!(Request.UrlReferrer == null)) 
       { 
        prevPage = Request.UrlReferrer.ToString(); 
       } 
      } 

      if (Request.QueryString["Id"] == null) 
      { 
       //prevPage = Request.UrlReferrer.ToString(); 
       if (!IsPostBack) 
       { 
        DetailsView1.ChangeMode(DetailsViewMode.Insert); 
       } 



      } 


     } 

     protected void DetailsView1_ItemInserted(object sender, DetailsViewInsertedEventArgs e) 
     { 
      Response.Redirect("ms_Ticket.aspx"); 
     } 




    } 
}

namespace Rise_cs.Ticket { 


    public partial class WebForm4 { 

     /// <summary>

你可以试试这个，让我知道吗？

protected void dtv_ItemInserted(object sender, DetailsViewInsertedEventArgs e) 
{ 
    Response.Redirect("page.aspx"); 
}

编辑：替换此

<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" 
    DataKeyNames="Id" DataSourceID="SqlDataSource1" Height="50px" Width="125px">

与

<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="Id" 
      DataSourceID="SqlDataSource1" Height="50px" Width="125px" OnItemInserted="DetailsView1_ItemInserted"> 
     </asp:DetailsView>

，你忘了事件附加到您的DetailsView OnItemInserted="DetailsView1_ItemInserted"

谢谢，但即使如此，它只是在UpdatePanel中返回Detailsview的空白详细信息页面 – 2011-04-04 05:43:37

？请将您的代码和DetailsView代码放在后面。 – 2011-04-04 05:54:14

我发布了代码，谢谢 – 2011-04-04 06:02:15

我有同样的问题！经过一些调试后，我意识到在发布后DetailViewMode返回插入模式（我在aspx文件中定义的默认模式）。为了保证保存的值在更新的操作后可见，我必须调用Changemode来保证DetailView停留在EditMode上。
