First put a break point in web method and check whether the break point is reaching or not . if not then paste the code where you are passing dropdown selected value using ajax method.

Solution 1

If you google "jquery selected value from dropdown" you'll find many, many answers very easily.

Do this:

JavaScript

var selectedVal = $('#dropDownid').val();

Then you'll have to post what you are doing because that does work.

<asp:DropDownList ID="ddlsec" runat="server" onchange="selesectiondrop(this)">

var liste = document.getElementById('#ddlsec');
var selectedVal = $('#ddlsec').val();
alert(selectedVal);

So, debug it. What is $("#ddlsec").length? Is this inside a control or master page? If so, then the actual client id will not be ddlsec, but will have stuff added to the front.
