Hi,

First remove the runat="server" from the DIV and add a Hidde field with runat="server" on your aspx page like:

XML

<input type="hidden" id="hdHTML" runat="server" />

and now store the InnerHTML in the Hidden field

XML

<script type="text/javascript">
       $(document).ready(function () {
           $('#btnAssignJudToCourse').click(function () {
               $('#hdHTML').val($('#ulAndil').html());
           });
       });
   </script>

now on the cs page get the HTML like

C#

protected void btnAssignJudToCourse_Click(object sender, EventArgs e)
{
     string html = this.hdHTML.Value;
}

if you are using Master Page then the IDs for server controls may be different as it start with ContentBody_. please check it and use if you are using master page.
good luck.

if you are using the dive in code behind then its OK leave the Runat=server.
if you are using mster page then server control ID will be changed and btnAssignJudToCourse is no more access in the javascript, so you need to get its actual ID generated. Right click on the page--go to View Page Source and look you IDs for Button, Hidden Field and the Div. its will be Looks like ContentBody_btnAssignJudToCourse or ctl00_ContentBody_btnAssignJudToCourse, this should be get your self and use this ID (from the page source) in the jquery.
