I have an < asp:menu/> control and a hidden field.Now i am using jquery to change value of hidden field. Code is:-

C#

$(function() {

    $(".primaryStaticMenu  tr,td").each(function(index) {

        $(this).click(function() {

            if ($(this).attr("title") != "undefined"
                && $(this).attr("title").length > 0) {

                document.getElementById('ctl00_Hidden_Master_Location').value = $(this).attr("title");

                alert(document.getElementById('ctl00_Hidden_Master_Location').value);
                //return false;
            }
        });
    });
});

Server side code to get updated value is:-

String Get_cng_value = Hidden_Master_Location.Value;

But Hidden_Master_Location.Value shows null every time. can any one tell me how to get updated value of hidden field code behind.

What is causing the server-side code to run?

Hi,

Try using something like this:

C#

var val = Request.Form["ctl00_Hidden_Master_Location"];

If you can't find it, try inspecting:

C#

Request.Form.AllKeys

Hope it helps
