Asp .net hidden field can't set value with jquery

Question

I can't set the value of a hidden field with jquery in asp .net.

My hidden field is declared like this:

<asp:HiddenField runat="server" ID="hdnSelectedTicket" />

And this is how I set the value:

            alert(ticketID);
            $('#<%=hdnSelectedTicket.ClientID %>').val(ticketID);
            alert($('#<%=hdnSelectedTicket.ClientID %>').val());

Both alerts show the right value but when I fetch it at the server it is empty.

Answer 1

Set ClientIDMode="Static" and then you can use $('#hdnSelectedTicket').val(ticketID); to set the value in asp hidden field

like

asp:HiddenField ID="hdnSelectedTicket" runat="server" ClientIDMode="Static"

and

$('#hdnSelectedTicket').val(ticketID);

Answer 2

It turns out that I was putting the hidden field inside a div that was used as a model for jquery dialog. When I removed the hidden field from the div and place it somewhere else it worked.
