accessing session variables from code behind in javacscript

Question

I have set the session variable in backend(code behind ascx.cs page) where i want to access the same value in checkbox checked event in javascript ..

this is my code in javascript function

 $(document).ready(function () {
    $('#<%= gvPRCertInfo.ClientID %> input[type="checkbox"]').change(function () {

        var background1 = null;
        background1 = '<%= Session["FriendlyData"] %>';
        alert(background1); // i am getting this value 'system.data.dataset'
        if ($(this).is(':checked')) {
            var signValue = 
     $(this).closest('tr').children('td:eq(4)').html();

        }
    });
 });

This variable <%= Session["FriendlyData"] %> is a dataset and i have assigned some values in backend, now i want to access the same value in above js function

when i put alert I am getting value as System.data.dataset and i am not getting what is the value in session..

Could any one please help on how to get the dataset value in javascript function...

many thanks in advance

You need to stringify your codeback object in some way. For example,

//.aspx.cs
DataSet ds = GetMyDataSet();
Session["dataset"] = ds;

//.aspx
<script>
var ds = '<%=((DataSet)Session["dataset"]).GetXml()%>';
</script>

@EnigmaState You can accept the answer if you find it useful. – Alex Kudryashev Nov 29 '17 at 05:30
Sorry i did not use your solution .. i made it one hidden variable and i assigned value in code behind, accessed it in javascript file – Glory Raj Nov 29 '17 at 11:32
Code behind is the best solution. In such cases I use `var a = '';` (and set `.Text` in codebehind). The question is *did I answer the OP?* – Alex Kudryashev Dec 01 '17 at 03:51
