ASP.NET DetailsView return as blank after Insert

I have two pages: the first it's a gridview that bind to DataSet, the second one have DetailsView that bind to DataSet that is used for editing and inserting.

Upon insertion on DetailsView Page, I want to redirect to GridView Page.

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

The detail page allow a correct insert of the new record but after saving it return a blank page; how I can obtain to return to an updated gridview page?

I tried to use the ItemInserted event of the DetailsView but it simply don't fire.

Update:

as suggested I add the following code:

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

(with ms_Ticket being the gridview page) but the insert continue to return the blank detailsview.

Update:

here's the codebehind of the detail page:

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");
        }




    }
}

here's the design:

//     Le modifiche a questo file possono causare un comportamento non corretto e verranno perse se
//     il codice viene rigenerato. 
// </generato automaticamente>
//------------------------------------------------------------------------------

namespace Rise_cs.Ticket {


    public partial class WebForm4 {

        /// <summary>
        /// Controllo DetailsView1.
        /// </summary>
        /// <remarks>
        /// Campo generato automaticamente.
        /// Per la modifica, spostare la dichiarazione di campo dal file di progettazione al file code-behind.
        /// </remarks>
        protected global::System.Web.UI.WebControls.DetailsView DetailsView1;

        /// <summary>
        /// Controllo SqlDataSource1.
        /// </summary>
        /// <remarks>
        /// Campo generato automaticamente.
        /// Per la modifica, spostare la dichiarazione di campo dal file di progettazione al file code-behind.
        /// </remarks>
        protected global::System.Web.UI.WebControls.SqlDataSource SqlDataSource1;
    }
}

Can you try this and let me know ?

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

Edit: Replace this

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

with

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

as you forgot to attach the event to your DetailsView OnItemInserted="DetailsView1_ItemInserted"

I had the same problem ! After some debug i realized that after the post the DetailViewMode was back to Insert mode ( Default mode that i defined in the aspx file). To garantee that the values saved were visible after the updated action i had to call the Changemode to garantee that the DetailView stayed on the EditMode.
