您要求使用CSS:
http://hicksdesign.co.uk/journal/highlighting-current-page-with-css
您应该能够实现在控件上使用静态ID命名(而不是让ASP.NET为每个控件分配ID值)。
You should be able to achieve that using static ID naming on your controls (instead of letting ASP.NET assign the ID value to each control).
编辑:
要想使用母版页,请将母版页中的< body>
标记更改为:
<body runat="server" clientidmode="Static" id="MasterBody">
然后在每个页面的Page_Load中,您可以覆盖每个页面的ID我的例子是类型 SiteMaster
):
Then in the Page_Load of each page, you can overwrite the id for each page (the master page in my example is of type SiteMaster
):
protected void Page_Load(object sender, EventArgs e)
{
Control c = Page.Master.FindControl("MasterBody");
if (c != null)
{
c.ID = "Page1";
}
}
我试过运行Farzin的例子,它似乎不工作,所以这里是我能够验证为我工作(你不需要 Page_Load
):
Site.master
<asp:Menu ID="NavigationMenu" ...>
<StaticSelectedStyle CssClass="selected" />
...
</asp:Menu>
Site.master.cs
protected void Page_Load(object sender, EventArgs e)
{
foreach (MenuItem item in NavigationMenu.Items)
{
item.Selected = Page.ResolveUrl(item.NavigateUrl).ToLowerInvariant() == Request.Path.ToLowerInvariant();
}
}
Styles / Site.css
div.menu ul li a.selected
{
/* put your style definition here */
}
