Add to List from codebehind C# Asp.net
You need to mark your ul as a server side control, then treat the 'new item' as a HtmlGenericControl
and insert it into the control collection:
<ul runat="server" id="tabs">
To add the item, create a new element and add it:
HtmlGenericControl li = new HtmlGenericControl("li");tabs.Controls.Add(li);HtmlGenericControl anchor = new HtmlGenericControl("a");anchor.Attributes.Add("href", "page.htm");anchor.InnerText = "TabX";li.Controls.Add(anchor);
Use asp:bulletedList and your list will be much easier.
<asp:BulletedList id="blTabs" BulletStyle="Disc" DisplayMode="LinkButton" runat="server"> <asp:ListItem Value="ztab1.htm">tab1</asp:ListItem> <asp:ListItem Value="ztab2.htm">tab2</asp:ListItem> <asp:ListItem Value="ztab3.htm">tab3</asp:ListItem></asp:BulletedList>
Code Behind:
ListItem li = new ListItem(); li.Value = "*.html"; //html goes here i.e. xtab1.html li.Text = "New Text"; //text name goes i.e. here tab1 blTabs.Items.Add(li);
This result is the same as GenericTypeTea's, but the difference is the HTML is 'written' in the code behind and injected into the page.
In your markup:
<asp:Literal id="litMarkup" runat="server" />
In your code behind:
List<string> locations // however this initialized StringBuilder sb = new StringBuilder();sb.Append("<ul id=\"tabs\">");for (int i = 0; i < locations.Count; i++){ sb.Append("<li id=\"tab" + i.ToString() + "\"><a href=\"" + locations[i] + "\">Tab " + i.ToString() + "</a></li>");}sb.Append("</ul>");litMarkup.Text = sb.ToString();
