How to pass a query string variable?

Question

I want to pass a class variable from 1 page to another page on link button click. The link button click event is written in the javascript query as follows:

<script type="text/javascript">
        function RedirectTo() {
            window.location.href = 'ApplyJobsByCandidate.aspx';
            return false;
        }

Now how can i pass a class variable through the query string? I want something like 'ApplyJobsByCandidate.aspx?id='+Class1.ID;

Please help me.

Make sure `Class1.ID` is accessible and has a value within the scope of your `RedirectTo` function. — Simon Belanger, Aug 07 '13 at 12:37

You can pass in the value into the function, then access add it into the query string

<script type="text/javascript">
        function RedirectTo(id) {
            window.location.href = 'ApplyJobsByCandidate.aspx?id=' + id;
            return false;
        }

in code behind

    public string ss
    {
        get
        {
            return ViewState["ss"].ToString();
        }
        set
        {
            ViewState["ss"] = value;
        }
    }

in some mothod set ss value like

ss = Class1.ID

in javascript

  <script type="text/javascript">
    function RedirectTo() {
        window.location.href = 'ApplyJobsByCandidate.id=' + '<%= ss %>';
        return false;
    }
</script>

Might as well just embed the `<%= ss %>` within the string and skip the concatenation. And the URL is invalid. – Simon Belanger Aug 07 '13 at 12:39

Try

<script type="text/javascript">
    function RedirectTo() {
        window.location.href = 'ApplyJobsByCandidate.aspx?Id=' +Id;
        return false;
    }
</script>

In C# Code

   if (Request.QueryString["id"] != null) {
        try
        {
            id = int.Parse(Request.QueryString["id"]);
        }
        catch
        {
            // deal with it
        }
    }

If you have a public static property within a class, then you can access it like so;

window.location.href = '<%=string.format("ApplyJobsByCandidate.aspx?id={0}", MyClass.id)%> ';

Another way to set class value into hidden field and send that value

Js code:

var getValue= $("#hiddenField1").val();
window.location.href = 'ApplyJobsByCandidate.aspx?id=' + getValue;

Code behind: On ApplyJobsByCandidate.aspx.cs

if(Request.QueryString["id"] != null)
{
string fetch_id = Request.QueryString["id"];
}

If you have access to the class in your page, you can do.

<script type="text/javascript">
        function RedirectTo() {
            window.location.href = 'ApplyJobsByCandidate.aspx?id=<% =Class1.ID %>';
            return false;
        }
