Question

i use jquery serialize() with asp.net server controls.

        <asp:DropDownList ID="ddFirmaAd" runat="server" Width="180" Height="25">
        </asp:DropDownList>

when i print the array

ajaxRequest("AjaxServices/Insert.aspx", $("#aspnetForm").serialize(), $('#returnMessage'), 0, $(this)); 

 function ajaxRequest(pageURL, queryString, putArea, timeout, disabledCtrl) {
        if (disabledCtrl != null)
            disabledCtrl.attr("disabled", "true");
        $.ajax({
            async: true,
            timeout: timeout,
            cache: false,
            url: pageURL + "?" + queryString,  


alert($("#aspnetForm").find("input,textarea,select,hidden").not("#__VIEWSTATE,#__EVENTVALIDATION").serialize());

it prints ddFirmaAd client name on window =”ct100%24ct100%24ContentPlaceHolder1%24ContentPlaceHolder1%24ddFirmaAd = 2 “

i want to get ddFirmaAd.selectedValue on code behind

string value = request.queryString("ddFirmaAd");

but the control name = ct100%24ct100%24ContentPlaceHolder1%24ContentPlaceHolder1%24ddFirmaAd

how to i use serialize() and .net controls ?

Answer 1

How about string value = request.QueryString(ddFirmaAd.ClientID);

but if you pass these values to a different page you can hack it like this:

string value = GetValueById("ddFirmaAd");

private string GetValueById(string endsWith)
    {
        var qs = HttpContext.Current.Request.QueryString;
        foreach(var key in qs)
        {
            string skey = key.ToString();
            if(skey.EndsWith(endsWith))
            {
                return qs[skey];
            }

        }
        return string.Empty;
    }

Not saying that it’s correct. Simply cannot come up with anything better based on the currently provided problem description.

You can configure ClientIDMode to static but then maintaining unique IDs becomes your responsibility and might lead to hard to find client side bugs.
