c# - Rowcommand が正しく機能しないのは、最初のリンクボタンの詳細のみが detailsView に表示されますか?

Question

GridView

<asp:GridView ID="gview1" runat="server" AutoGenerateColumns="False" 
GridLines="Horizontal" AutoGenerateRows="false" 
onrowcommand="gview1_RowCommand"onDataKeyNames="lId,lName"BackColor="White" 
BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3" 
  CssClass="gridview1" >
  <AlternatingRowStyle BackColor="#DCDCDC" />
   <Columns>
    <asp:TemplateField HeaderText="Search Results">
     <ItemTemplate>
       <asp:HiddenField ID="hdnFieldLid"runat="server"Value='<%#Eval("lId")%>'  />
                    <asp:LinkButton ID="link" runat="server" Text='<%# Eval("lName") %>'
                     CommandArgument='<%# ((GridViewRow) Container).RowIndex %>'
                     CommandName="select" ></asp:LinkButton>
                     </ItemTemplate>
            </asp:TemplateField>
        </Columns>

GridView の背後にあるコード

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        get_search();
    }
       }

public void get_search()
{
    SqlCommand cmd = new SqlCommand();
    cmd.CommandText = "lichen_Namesearch";
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.Connection = con;
    cmd.Parameters.Clear();
    cmd.Parameters.AddWithValue("@lName", Session["lName"].ToString());
    cmd.Parameters.AddWithValue("@uName", Session["uName"].ToString());
    cmd.Parameters.AddWithValue("@cName", Session["cName"].ToString());
    cmd.Parameters.AddWithValue("@sName", Session["sName"].ToString());
    DataTable dt = new DataTable();
    SqlDataAdapter adp = new SqlDataAdapter(cmd);
    adp.Fill(dt);
    gview1.DataSource = dt;
    gview1.DataBind();
}



protected void gview1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "select")
    {
        int index = Convert.ToInt32(e.CommandArgument.ToString());
        LinkButton lnkBtn = (LinkButton)gview1.Rows[index].FindControl("link");
        HiddenField hdnFieldlid = (HiddenField)gview1.Rows[index].FindControl("hdnFieldLid");
        Session["lName"] = lnkBtn.Text.Trim();
        Response.Redirect("../RealDatabase/Default2.aspx");
    }
}

Default2 は、DetailsView が構成されている次のページです。

DetailsView のコード ビハインド

    protected void Page_Load(object sender, EventArgs e)
    {
       get_searchDetails();  //search function
      }
      public void get_searchDetails()
    {
         SqlCommand cmd = new SqlCommand();
         cmd.CommandText = "get_lichenDetails";
         cmd.CommandType = CommandType.StoredProcedure;
         cmd.Connection = con;
         cmd.Parameters.Clear();
         cmd.Parameters.AddWithValue("@sName", Session["sName"].ToString());
         cmd.Parameters.AddWithValue("@uName", Session["uName"].ToString());
         cmd.Parameters.AddWithValue("@lName", Session["lName"].ToString());
         cmd.Parameters.AddWithValue("@cName", Session["cName"].ToString());
         DataTable dt = new DataTable();
         SqlDataAdapter adp = new SqlDataAdapter(cmd);
         adp.Fill(dt);
         DetailsView1.DataSource = dt;
         DetailsView1.DataBind();
      }
