用户控件中引用JS或者CSS文件

// 引入js文件
            HtmlGenericControl scriptControl = new HtmlGenericControl("script");
            scriptControl.Attributes.Add("type", "text/javascript");
            scriptControl.Attributes.Add("language", "JavaScript");
            scriptControl.Attributes.Add("src", "../js/menu.js");
            Page.Header.Controls.Add(scriptControl);
// 引入样式表
             Literal cssControl = new Literal();
            cssControl.Text = "<link href=\"../css/menu.css\" rel=\"stylesheet\" type=\"text/css\"/>";
            Page.Header.Controls.Add(cssControl);

引入js还可以利用：
if (!Page.ClientScript.IsClientScriptIncludeRegistered("menu"))
            Page.ClientScript.RegisterClientScriptInclude(this.GetType(), "menu",
                Page.ResolveClientUrl(@"~/menu/menu.js"));

page类的东西蛮多的，呵呵~
