<asp:TemplateField HeaderText="查看">
                        <HeaderStyle HorizontalAlign="Left" Width="8%" />
                        <ItemStyle HorizontalAlign="Left" Width="8%" />
                        <ItemTemplate>
                           <a id="picPath" href='<%#Bind(ftp:"PicPath") %>' runat="server" target="_blank">查看</a>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="下载">
                        <HeaderStyle HorizontalAlign="Left" Width="8%" />
                        <ItemStyle HorizontalAlign="Left" Width="8%" />
                        <ItemTemplate>
                            <asp:LinkButton ID="downLB" runat="server" CommandArgument='<%#Bind("PicID") %>' CommandName="downLB">下载</asp:LinkButton>
                        </ItemTemplate>
                    </asp:TemplateField>
后台：
  string url="";
        if (e.CommandName == "downLB")
        {//下载
            try
            {
                Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(scp.PicPath, System.Text.Encoding.UTF8));
                Response.WriteFile(url);
                Response.Flush();
                Response.ClearContent();
                Response.End();
            }
            catch (Exception)
            { }
        }
