GridView 取值问题 c#.net

现在一个GridView控件输出三列数据 分别为NewsTitle1 ,NewsDEC ,SN列。 NewsTitle1列已经被设为超链接
当你点一个NewsTitle1中的数据时，session自动取得取值想对应的SN值  请问应该怎样写 最好为C#.net语言

解决方案 »

  1.   

    试试这种方式：<asp:HyperLinkField DataNavigateUrlFields="SN" DataNavigateUrlFormatString="test.aspx?SN={0}" DataTextField="NewsTitle1" HeaderText="NewsTitle1"></asp:HyperLinkField>
      

  2.   

    html页： 
          <asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" OnRowCommand="GridView2_RowCommand">
                <Columns>
                     <asp:BoundField DataField="u_id" ReadOnly="True" HeaderText="编号" />
                    <asp:BoundField DataField="u_loginname" HeaderText="标识" ReadOnly="True" />
                    <asp:TemplateField>
                        <ItemTemplate>
                        <asp:LinkButton ID="lb_edit" runat ="server" Text ='<%# Eval("NewsTitle1") %>' CommandName ="edit" CommandArgument ='<%# Eval("SN") %>'></asp:LinkButton>
                        </ItemTemplate>                    </asp:TemplateField>
                </Columns>
            </asp:GridView>
    aspx.cs页： protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName == "edit")
            {
                Response.Redirect("Default2.aspx?sn=" + e.CommandArgument.ToString());
            }        }
