C# ASP.NET详细信息视图在插入后返回为空

我有两个页面：第一个是绑定到DataSet的gridview，第二个是绑定到DataSet的DetailsView，用于编辑和插入

在DetailsView页面上插入后，我想重定向到GridView页面

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

详细信息页允许正确插入新记录，但保存后返回空白页；如何获得返回到更新的gridview页面的权限

我试图使用DetailsView的ItemInserted事件，但它根本无法启动

更新：

根据建议，我添加了以下代码：

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

（MSS票为GRIDVIEW页），但插入继续返回空白DealIsVIEW。< /P> 更新：

以下是详细信息页面的代码隐藏：

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");
        }




    }
}

你能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">

由于您忘记将事件附加到您的DetailsView

OnItemInserted=“DetailsView 1\u ItemInserted”

中，我遇到了同样的问题！经过一些调试后，我意识到在post之后，DetailViewMode回到了插入模式（我在aspx文件中定义的默认模式）。为了保证更新操作后保存的值是可见的，我必须调用Changemode来保证DetailView保持在EditMode上<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="Id" DataSourceID="SqlDataSource1" Height="50px" Width="125px" OnItemInserted="DetailsView1_ItemInserted"> </asp:DetailsView>
