简单的asp.net web表单与选定的类UL李菜单 [英] simple asp.net webforms ul li menu with selected class
问题描述
我在它的链接一个简单的无序列表。
I have a simple unordered list with links in it.
<body>
<div id="topMenu">
<ul>
<li><a class="selected" href="../Default.aspx">Start</a></li>
<li><a href="../Category/ShowAll.aspx">Categories</a></li>
<li><a href="../Elements/ShowAll.aspx">Elements</a></li>
<li><a href="../Articles/ShowAll.aspx">Articles</a></li>
</ul>
</div>
<asp:ContentPlaceHolder ID="MainContentPlaceholder" runat="server">
</asp:ContentPlaceHolder>
</body>
我想修改类的链接我点击了选择了类，这是做到这一点的最简单方式。我想过使它成为linkbuttons并保存在会话中的信息，但似乎矫枉过正，必须有一个更简单的方法呢？
I want to change the class of the link i click to the "selected" class, which is the easiest way to do this. I thought about making it into linkbuttons and saving the info in the session, but that seems overkill, there has to be an easier approach?
推荐答案
好了，你可以把＆LT; A＆GT; 是 RUNAT =服务器，然后从codebehind访问它们：
Well, you can just put the <a> to be runat="server" and then access them from codebehind:
hyperLink.Attributes["class"] = "opened";
您可以与您的菜单母版页有这样的，他们需要选择的，你可以有你的孩子送网页的超级链接的ID，像
You can have this in your master page with the menu, and you can have your child pages send the id of the hyperlink they need selected, something like
在你的主人（该linkWrapper可以成为你的＆LT; UL＆GT; 为 RUNAT服务器）：
In your master (the linkWrapper can be your <ul> as runat server):
(HyperLink)linkWrapper.FindControl(childPageMenuAnchorLinkId);
在你的孩子：
masterPage.ChildPageMenuAnchorLinkId = "link_Customers";
