Answer 1

Add id and runat="server" to the list item:

 <li id="fooItem" runat="server"> <%-- ... --%> </li> 

Set the visibility property from the code behind (C # example):

 if (someBool) { fooItem.Visible = false; } 

You can also use this approach to apply / remove a style:

 if (someBool) { fooItem.Attributes.Add("class", "foobar"); // or removing a style foobarItem.Attributes.Remove("class"); } 

Answer 2

You can access the Html element as a GenericHtmlControl by adding the runat = 'Server' attribute to the markup, then you can access the property programmatically, as if it were the normal ASP.Net user interface.

 <li ID="hide" style="display: Block;" runat="Server"><a href="../list.aspx" >list Approval</a></li> HtmlGenericControl listItem = this.hide as HtmlGenericControl; if (listItem != null) this.hide.style.Add("display", "none"); 

Answer 3

 <asp:Panel ID="Panel1" runat="server"> <div > //place here your list </div> </asp:Panel> 

and with C # you can hide the panel
