Add <li> to <ul> tag from code behind C# ASP NET
Question
well how the title says, how can I add various <li> tags to a <ul> tag from code behind. I tried this Add to List from codebehind C# Asp.net this is my example code.
ASP
<body>
<form id="form1" runat="server">
<div>
<ul id="menu" runat="server"> </ul>
</div>
</form>
And code behind.
protected void Page_Load(object sender, EventArgs e)
{
CreateMenu();
}
protected void CreateMenu()
{
HtmlGenericControl li = new HtmlGenericControl("li");
menu.Controls.Add(li);
HtmlGenericControl anchor = new HtmlGenericControl("a");
anchor.Attributes.Add("href", "login.aspx");
anchor.InnerText = "login";
li.Controls.Add(anchor);
}
Well it works perfectly but maybe this gonna be a dumb question, how can I add more than one element to the <ul> tag? I need to create an new object for each item (I think this is wrong) or exist a better way to do this?
I searched but any example satisfies my doubt, sorry if you think is a repeated question.

If your datas(menu items) are not coming from a source(something like database), you need to repeat the same process over and over again unfortunately. Or you can create a function which is taking 2 parameters, text and link. This way you can do this job with 1 line.
private void AddMenuItem(string text, string link)
{
HtmlGenericControl li = new HtmlGenericControl("li");
menu.Controls.Add(li);
HtmlGenericControl anchor = new HtmlGenericControl("a");
anchor.Attributes.Add("href", link);
anchor.InnerText = text;
li.Controls.Add(anchor);
}
AddMenuItem("text","link");
AddMenuItem("text2","link2");
AddMenuItem("text3","link3");
You can improve this for your specific needs.

You can use ListView. It's easier format. I also found a good tutorial about it ( http://weblogs.asp.net/scottgu/the-asp-listview-control-part-1-building-a-product-listing-page-with-clean-css-ui )
<asp:ListView ID="ListView1" runat="server">
<LayoutTemplate>
<ul>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</ul>
</LayoutTemplate>
<ItemTemplate>
<li>
<div>
<p class="name"><%# Eval("author") %></p>
<p class="date"><%# Eval("insertDate") %></p>
</div>
<p class="comment"><span class="<%# Eval("icon") %>"></span><%# HttpUtility.HtmlEncode(Eval("comment")) %></p>
</li>
</ItemTemplate>
</asp:ListView>
