 /*

* <param name="key">A string contains the querystring key</param>
* <param name="defaultVal">Object which get returns when there is not key</param>

function getQuerystring(key, defaultVal) {
    if (defaultVal == null) {
        defaultVal = "";
    }
    key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
    var regex = new RegExp("[\\?&]" + key + "=([^&#]*)");
    var qs = regex.exec(window.location.href);
    if (qs == null) {
        return defaultVal;
    }

Store the value of QueryString in Label or HiddenField, and get the stored value from document.getElementById('Label').value. Pass this value in the window.open url.

You can get a hold of the url using window.location.search

Check How can I get query string values in JavaScript? for a good answer for parsing the Querystring into something useful.

So with that you can access your param by going

window.open('/Tarif_Report.aspx?Id=' + urlParams["Id"]);

Create a public property in page.
During page load event set that property by getting the value from query string.
In ASPX page get the value using <% = this.PropertyName; %>

i got it:

 <script type="text/javascript">


        function getParameterByName(name)
        {
          name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
          var regexS = "[\\?&]" + name + "=([^&#]*)";
          var regex = new RegExp(regexS);
          var results = regex.exec(window.location.href);
          if(results == null)
            return "";
          else
            return decodeURIComponent(results[1].replace(/\+/g, " "));
        }
      </script>


     <dx:ASPxButton ID="ASPxButton_RptTarif" runat="server" Text="Voir" AutoPostBack="False">
                                                                    <ClientSideEvents
                                                                    Click="function (s, e) { e.processOnServer = false; window.open('../Tarif_Report.aspx?ClientID=' + getParameterByName('Id')); }" />
                                                                </dx:ASPxButton>
