ASP您好，我正在处理一个用和编写的网页C#，我可以在其中添加edit and delete来自database. 该网页的每一行都grid view包含 a select, edit and delete links，并且这些行按日期排序。所以我的问题是： 我怎样才能插入一条新记录，并自动转到相应的页面？（以网格视图页面大小为 5 为例）

这是网格视图的一部分

<asp:GridView ID="grdSchedulerApplications" runat="server" AutoGenerateColumns="False"
                            Visible="false" ShowFooter="True" PageSize="5" DataKeyNames="sa_ID, sa_ApplicationID"
                            AllowPaging="True" OnRowCommand="grdSchedulerApplications_RowCommand">
                            <Columns>
                                <asp:TemplateField HeaderText="Application" HeaderStyle-HorizontalAlign="Left">
                                    <EditItemTemplate>
                                        <asp:DropDownList ID="ddlEditSchedulerApplications" runat="server" AutoPostBack="True"
                                            DataTextField="app_Name" DataValueField="app_Id">
                                        </asp:DropDownList>
                                    </EditItemTemplate>
                                    <ItemTemplate>
                                        <%# Eval("Application")%>
                                    </ItemTemplate>
                                    <FooterTemplate>
                                        <asp:DropDownList ID="ddlSchedulerApplications" runat="server" AutoPostBack="True"
                                            DataTextField="app_Name" DataValueField="app_Id">
                                        </asp:DropDownList>
                                    </FooterTemplate>
                                </asp:TemplateField>

然后我有 C# 代码：

protected void grdSchedulerApplications_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName.Equals("Insert"))
        {
            try
            {
                int saSchdlrID;
                int.TryParse(grdBulkScheduler.SelectedDataKey.Values[0].ToString(), out saSchdlrID);
                DropDownList ddlSchedulerApps = (DropDownList)grdSchedulerApplications.FooterRow.FindControl("ddlSchedulerApplications");

                int appID;
                int.TryParse(ddlSchedulerApps.SelectedValue.ToString(), out appID);

                //calling a method from another class to add/update records into database
                object obj = cData.AddUpdateBulkSchedulerApplications(0, saSchdlrID, appID);

                //query returns the automatically incremented ID of newly created record into obj
                if (obj.ToString() != "0")
                {
                    //do some action
                    //here I need to go to the corresponding page Index
                }
            }
            catch (Exception ex)
            {
                //exception
            }
        }

如果数据源返回按日期排序的行并且您不修改此顺序，则需要设置页面索引并将网格重新绑定到其数据源：

if (obj.ToString() != "0")
{
    grdSchedulerApplications.PageIndex = Int32.Parse(obj) / 5;
    // TODO: Rebind your grid (set the data source and call DataBind())
}
