I saved the above html in a string variable. what can i do for this.

Answer 1

If you do this in the code behind, this is what I perceive as follows, try the following:

  var last = htmlString.LastIndexOf("<li>"); htmlString = htmlString.Remove(last, 4).Insert(last, "<li class=\"last\""); 

Answer 2

 string data = ...; string toReplace ="<li>"; string toPlace = "<li class=\"last\">"; int idx = data.LastIndexOf(toReplace); data = data.Remove(idx, toReplace.Length).Insert(idx, toPlace); 

Answer 3

Perhaps you can use jquery to achieve this:

 $("li:last").addClass("last") 

Answer 4

You can do this in jQuery as follows:

 $("#listid li:last").addClass("last");
