我正在尝试在新闻brief描述的末尾向我的新闻门户添加阅读更多选项。到目前为止，一切似乎都运行良好，显示了 20 条最新记录。但是只要我在 gridview 中添加这段代码。只显示第一条记录，阅读更多链接似乎不起作用。 

<asp:HyperLink ID="hlRead" runat="server" Font-Bold="True" Font-Size="Small" 
        Font-Underline="True" ForeColor="#0099FF" 
        NavigateUrl='<%# "news_details.aspx?id=" + Session["id"].ToString() %>'>Read More</asp:HyperLink>

这就是 ItemTemplate 的样子

  <ItemTemplate>
        <asp:LinkButton ID="name3" runat="server" 
        CommandArgument="<%# Container.DataItemIndex %>" CommandName="news" 
        Font-Underline="False" Text='<%# Eval("headlines_n") %>' Font-Bold="True" 
        Font-Size="Large" ForeColor="#0D8CCF" />
  <asp:Label ID="Label21" Visible="false" runat="server" Text='<%# Eval("nid") %>'></asp:Label>
 <br />
    <asp:LinkButton ID="LinkButton1" runat="server" 
        CommandArgument="<%# Container.DataItemIndex %>" CommandName="news" 
        Font-Underline="False" Text='<%# Eval("brief") %>' />
     &nbsp;<asp:HyperLink runat="server" Font-Bold="True" Font-Size="Small" 
        Font-Underline="True" ForeColor="#0099FF" 
        NavigateUrl='<%# "news_details.aspx?id=" + Session["id"].ToString() %>'> read more</asp:HyperLink>
     <br />
     <br />
</ItemTemplate>

这是服务器端代码：

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    switch (e.CommandName.Trim())
    {
        case "news":
            try
            {
                int r1 = Int32.Parse((e.CommandArgument).ToString());
                r1 = r1 % 9;
                Label lbid1 = (Label)GridView1.Rows[r1].FindControl("Label21"); //Label 21 fetches the newsid from the database. 
                Session["id"] = lbid1.Text;
                Response.Redirect("news_details.aspx?id=" + Session["id"]);
            }
            catch (Exception ex)
            {
                Response.Write(ex.ToString());

            }

            break;
    }
}
