select value can not be accessible from aspx code behind

I have to fetch the html select control value from the aspx code behind...I have done the following coding so far:

The following code snippet is the jquery to populate the dropdown:

<script type="text/javascript">
        $(document).ready(function () {       // load jQuery 1.5
            function loadfail() {
                alert("Error: Failed to read file!");
            }

            function parse(document) {
                $(document).find("combo").each(function () {
                    var optionLabel = $(this).find('text').text();
                    var optionValue = $(this).find('value').text();
                    $('#combo1').append(
                   '<option value="' + optionValue + '">' + optionLabel + '</option>'
                    );
                });
            }

            $.ajax({
                url: 'dropdown.xml',    // name of file with our data
                dataType: 'xml',    // type of file we will be reading
                success: parse,     // name of function to call when done reading file
                error: loadfail     // name of function to call when failed to read
            });
        });

    </script>

The following code snippet is the html select declaration:

<select id="combo1" ></select>

Can anybody please help me how to get the selected value of the dropdown in aspx code behind.

instead I have used the following trick

in .aspx page I have used this

<select id="combo1" name="a">

in .aspx.cs page I have used this

string strValue = Page.Request.Form["a"].ToString();

This gives me the index no and rest sorting I will do...

Your dropdown should be added runat=server

<select id="combo1" runat = "server"></select>

and your script need to be changed, because you changed html control to server control. so that your script will be like this,

function parse(document) {
                $(document).find($("#<%=combo1.ClientID %>")).each(function () {
                    var optionLabel = $(this).find('text').text();
                    var optionValue = $(this).find('value').text();
                    $('#').append(
                   '<option value="' + optionValue + '">' + optionLabel + '</option>'
                    );
                });
            }
