changing value of dropdownlist in label

Question

Hi everybody,

I have this:

[code]
public static IEnumerable<SelectListItem> GetWeekNumbers(this HtmlHelper helper /*Dictionary<int, DateTime> dayOfWeek*/  /*,DateTime allWeeks*/ /*int selectID*/)
        {
            var janFirst = new DateTime(DateTime.Today.Year, 1, 1);
            //beware different cultures.
            var firstWeek = janFirst.AddDays(1 - (int)(janFirst.DayOfWeek));
            int j = -1;
            foreach (var weekNumber in Enumerable.Range(0, 52).Select(i => new
            {
                weekStart = firstWeek.AddDays(i * 7),
                //Tuesday = firstWeek.AddDays(i * 3)
            }).TakeWhile(x => x.weekStart.Year <= janFirst.Year).Select(x => new
            {
                x.weekStart,
                weekFinish = x.weekStart.AddDays(6)
            }).SkipWhile(x => x.weekFinish < janFirst.AddDays(1)))
            {
                j++;
               yield return new SelectListItem
                {
                  
                    Value = string.Join(",",new string[]
                    {
                       
                      
                       weekNumber.weekStart.ToShortDateString(),
                       weekNumber.weekStart.AddDays(1).ToShortDateString(),
                       weekNumber.weekStart.AddDays(2).ToShortDateString(),
                       weekNumber.weekStart.AddDays(3).ToShortDateString(),
                       weekNumber.weekStart.AddDays(4).ToShortDateString(),
                       weekNumber.weekStart.AddDays(5).ToShortDateString(),
                       weekNumber.weekStart.AddDays(6).ToShortDateString(),

                    }),
                   
                    Text = (j + 1).ToString(CultureInfo.InvariantCulture)
                };
            }
        }//end method
[/code]

and for the view:

[code]
 <td>
                   
                    <div class="editor-field">
                        @Html.Label("txtBox", Model.Monday.ToLongDateString())
                        @Html.ValidationMessageFor(model => model.Monday)
                    </div>
                </td>
[/code]

and the JQuery:

[code]
function Selectedchange() {
            $("#txtBox").val($("#weekId").val().toString().split(",") [0]);
}
[/code]

but the selected value doesnt change in the label.

But If I do a textBox, like this:

[code]
</div>
                    <div class="editor-field">
                        @Html.TextBox("txtBox", Model.Monday.ToLongDateString())
                        @Html.ValidationMessageFor(model => model.Monday)
                    </div>
[/code]

then the value change.

But how to manage it in the html.Helper: Label?

THX for helping.
