C# 如何为中继器中嵌套的子gridview提供导航

我需要您的帮助，我有一个嵌套的中继器父级（

Repeater1

）和子gridview（

gvNewChild

）。父中继器正在从父表调用记录Id（

FId

），子gridview正在从子表获取父中继器的

OnItemDataBound

上的记录Id（

FId

），因此父表和子表都不同，但与

FId

链接，后者在两个表中都是相同的记录Id号

现在，我可以分别使用它们的

FId

从两个表中检索outer repeater和child gridview中的数据。但是我想知道是否有可能在child gridview中提供导航，而不是一次显示所有记录，所以实际上我希望我的child repeater只显示一条记录，并访问我想使用下一条和上一条导航的其他记录。请引导我，下面是代码：

GridView ID=“gvNewChild”runat=“server”DataKeyNames=“FId”AutoGenerateColumns=“false”
CssClass=“tableWall”HeaderStyle BorderColor=“#ffffff”GridLines=“无”可见=“真”
AllowPagin=“true”PageSize=“1”OnPageIndexChanging=“gvNewChild\u PageIndexChanging”>

资料来源如下：

if (!IsPostBack)
{
    Repeater1.DataSource = GetData("select *from News order by (Id) desc");
    Repeater1.DataBind();
}

private static DataTable GetData(string query)
{
    string strConnString = ConfigurationManager.ConnectionStrings["BHCONNECTION"].ConnectionString;
    using (SqlConnection con = new SqlConnection(strConnString))
    {
        using (SqlCommand cmd = new SqlCommand())
        {
            cmd.CommandText = query;
            using (SqlDataAdapter sda = new SqlDataAdapter())
            {
                cmd.Connection = con;
                sda.SelectCommand = cmd;
                using (DataSet ds = new DataSet())
                {
                    DataTable dt = new DataTable();
                    sda.Fill(dt);
                    return dt;
                }
            }
        }
    }
}

protected void OnItemDataBound(object sender, RepeaterItemEventArgs e)
{ 
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        string FId = (e.Item.FindControl("hfFId") as HiddenField).Value;
        Repeater rptOrders = e.Item.FindControl("rptOrders") as Repeater;
        rptOrders.DataSource = GetData(string.Format("select * from NewsPic where FId='{0}'", FId));
        rptOrders.DataBind();
    }
}


 protected void gvNewChild_PageIndexChanging(object sender, GridViewPageEventArgs e)
    { 
        GridView gvNewChild = (sender as GridView);
        gvNewChild.PageIndex = e.NewPageIndex;
        gvNewChild.DataBind();

    }

@阿西夫，它就像一个魅力！！！谢谢你的救命恩人。但是我可以用下一个和上一个导航代替页码吗？很抱歉打扰你，你可以点击这个链接@Asif，但我现在检查了，它显示了一些记录，而没有显示一些记录（子记录-Gridview）。就是这样，它在每个记录之后都会跳过，例如记录1显示，记录2不显示，但记录3显示，记录4不显示等等。。。你能给我最后一个帮助吗？请尝试很久。@Asif我在这里弄明白了：if（e.Item.ItemType==ListItemType.Item | | | e.Item.ItemType==ListItemType.AlternatingItem）那么如果（e.Item.ItemType==ListItemType.AlternatingItem）这个
