Print Crystal Report on Client Side using JavaScript in ASP.Net

I have used the code used in my article Create Crystal Report using Stored Procedure in ASP.Net with C# and VB.Net

HTML

I have placed the Crystal Report in an HTML DIV.

<div id = "dvReport">
<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="true"
    Height="400" Width="600" BestFitPage="False" />
    </div>
<br />
<asp:Button ID="btnPrint" Text="Print" runat="server" OnClientClick = "return Print()" />

JavaScript

In JavaScript the following funciton is executed which prints the Crystal Report.

<script type="text/javascript">
        function Print() {
            var dvReport = document.getElementById("dvReport");
            var frame1 = dvReport.getElementsByTagName("iframe")[0];
            if (navigator.appName.indexOf("Internet Explorer") != -1) {
                frame1.name = frame1.id;
                window.frames[frame1.id].focus();
                window.frames[frame1.id].print();
            }
            else {
                var frameDoc = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.document ? frame1.contentDocument.document : frame1.contentDocument;
                frameDoc.print();
            }
        }
</script>
