Question

好吧，当我构建解决方案时，我在代码隐藏文件中访问母版页的标签控制时遇到了问题，它给出了错误： “在当前背景下，'lbllogin'这个名字并不存在” 任何人都可以告诉我如何解决这个问题......

这是我的masterpage.master文件代码：

<%@ Master Language="C#" AutoEventWireup="true"  CodeFile="Masterpage.master.cs" Inherits="Masterpage" %>

<!DOCTYPE html>

        function mainmenu() {
            $(" #nav ul ").css({ display: "none" });
            $(" #nav li ").hover(function () {
                $(this).find('ul:first').css({ visibility: "visible", display: "none" }).show(400);
            }
            , function () {
                $(this).find('ul:first').css({ visibility: "hidden" });
            });
        }
            $(document).ready(function(){
                mainmenu();
        });

尝试使用'This'关键字访问控件..

例如

This.lbllogin.Text = "error";

希望这会有所帮助..
