博客介绍了在ASP中动态添加CSS样式表的两种方法。方法一是通过Page.RegisterStartupScript添加样式表；方法二则是利用asp:placeholder控件，创建LINK元素并添加到占位符中。还提到asp:placeholder控件起占位作用。
方法一:
<HEAD>
<title>WebForm1</title>
<LINK rel="stylesheet" type="text/css" href="" id="mycss">
</HEAD>
private void Button1_Click(object sender, System.EventArgs e)
{Page.RegisterStartupScript("css",@"<script>mycss.styleSheet.addImport('stylesheet1.css')</script>");
}
方法二:--- 戏子的方法..嘻..抄来的...
<HEAD>
<title>WebForm1</title>
<asp:placeholder id="myplaceholder" runat="server"></asp:placeholder>
</HEAD>
private void Button2_Click(object sender, System.EventArgs e)
{
System.Web.UI.Control a = Page.FindControl("myplaceholder");
System.Web.UI.HtmlControls.HtmlGenericControl objLink = new HtmlGenericControl("LINK");
objLink.Attributes.Add("rel","stylesheet");
objLink.Attributes.Add("type","text/css");
objLink.Attributes.Add("href","StyleSheet1.css");
objLink=objLink;
a.Controls.Add(objLink);
}
[注] asp:placeholder 这是控件是主要是起"占位符的做用"
<HEAD><title>WebForm1</title><LINK rel="stylesheet" type="text/css" href="" id="mycss"></HEAD> private void Button1_Click(object sender, System.EventArgs e) {Page.RegisterStartupScript("css",@"<script>mycss.styleSheet.addImport('stylesheet1.css')</script>"); } 方法二:--- 戏子的方法..嘻..抄来的...
<HEAD> <title>WebForm1</title> <asp:placeholder id="myplaceholder" runat="server"></asp:placeholder> </HEAD> private void Button2_Click(object sender, System.EventArgs e) { System.Web.UI.Control a = Page.FindControl("myplaceholder"); System.Web.UI.HtmlControls.HtmlGenericControl objLink = new HtmlGenericControl("LINK"); objLink.Attributes.Add("rel","stylesheet"); objLink.Attributes.Add("type","text/css"); objLink.Attributes.Add("href","StyleSheet1.css"); objLink=objLink; a.Controls.Add(objLink); } [注] asp:placeholder 这是控件是主要是起"占位符的做用"
