当我点击gridview中的新页面时出现奇怪的行为，就像我点击了一行一样

Question

首先我的HTML

<asp:GridView ID="GridViewCustomers" runat="server" AutoGenerateColumns="False" 
            AllowPaging="True" datakeynames="Reservation_ID,Excursion_ID"
            onpageindexchanging="GridViewCustomers_PageIndexChanging"
            onrowcommand="GridViewCustomers_SelectedIndexChanged" 
             BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal" >

            <AlternatingRowStyle BackColor="#F7F7F7" />

            <Columns>
                <asp:CommandField ShowSelectButton="True" />
                <asp:BoundField DataField="Reservation_ID" HeaderText="РЕЗ. №" />
                                <asp:BoundField DataField="Name"  HeaderText="Име на Екскурзия" />
                                <asp:BoundField DataField="Reservation_TotalAmount"  HeaderText="Сума по резервацията" />

                <asp:BoundField DataField="Excursion_ID" Visible="false" />

                <asp:BoundField DataField="ReservationDate" HeaderText="Дата на заминаване" />

               <asp:TemplateField HeaderText="Имена на Туристи">
            <ItemTemplate>
                <asp:Repeater ID="Repeater1" runat="server" DataSource='<%# Eval("TouristName") %>'>
                    <ItemTemplate>
                        <%# (Container.ItemIndex+1)+"."+ Container.DataItem  %><br />
                    </ItemTemplate>
                </asp:Repeater>
            </ItemTemplate>
             </asp:TemplateField>

            </Columns>
            <FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
            <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#F7F7F7" />
            <PagerStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" HorizontalAlign="Right" />
            <RowStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" />
            <SelectedRowStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />
            <SortedAscendingCellStyle BackColor="#F4F4FD" />
            <SortedAscendingHeaderStyle BackColor="#5A4C9D" />
            <SortedDescendingCellStyle BackColor="#D8D8F0" />
            <SortedDescendingHeaderStyle BackColor="#3E3277" />
        </asp:GridView>

因此，在代码中，您将点击选择按钮，我获得值od datakeyna并将用户重定向到另一个页面。问题是当我点击gridview的第2页时，我被重定向到另一页，就像我选择了一行一样。

    protected void Page_Init(object sender, EventArgs e)
    {
        this.lstUserReservations.AddRange(lstUserReservations);
        this.lstUserReservations.AddRange(lstUserReservations);
        this.lstUserReservations.AddRange(lstUserReservations);
    }
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            User_Reservation trr = new User_Reservation();
            lstUserReservations = new List<User_Reservation>();
            lstUserReservations = LoadReservationsForUser();
            GridViewCustomers.DataSource = lstUserReservations;
            GridViewCustomers.DataBind();
        }

    }

    protected void GridViewCustomers_SelectedIndexChanged(object sender,  GridViewCommandEventArgs e)

    {  int indexer = Int32.Parse(e.CommandArgument.ToString()); 
                   Session["еxcursion_id"] = this.GridViewCustomers.DataKeys[indexer].Values["Excursion_ID"].ToString();
        Response.Redirect("ReservationInfo.aspx");

    }
    protected void GridViewCustomers_PageIndexChanging(object sender,
       System.Web.UI.WebControls.GridViewPageEventArgs e)
    {
        this.GridViewCustomers.PageIndex = e.NewPageIndex;
         this.GridViewCustomers.DataBind();
    }

}

你看我有

您需要处理一些轻微的代码。如果要更改分页，请检查是否已单击分页并返回（如果有）或者选择该行。此外，当您更改分页时，RowCommand事件首先在PageIndexChanging事件之后。

protected void GridViewCustomers_SelectedIndexChanged（object sender，GridViewCommandEventArgs e）

{  
    if(e.CommandName == "Page")
        return;
    int indexer = Int32.Parse(e.CommandArgument.ToString()); 
    Session["еxcursion_id"] = this.GridViewCustomers.DataKeys[indexer].Values["Excursion_ID"].ToString();
    Response.Redirect("ReservationInfo.aspx");

}

如果这对您有用，请告诉我。
