[DevExpress Support Team: CLONED FROM T818267: Print Report button does not work after Google Chrome Update]

Hello,
I have the same problem as Chandana has . After adding the source code to my report.aspx page, my report page wouldn't load the report. Screenshot is attached.

ASPx
<dx:ReportViewer ID="InterimStatus_RegionFIViewer" runat="server" PageByPage="True">  
    <ClientSideEvents PageLoad="init"/>  
</dx:ReportViewer>

<script type="text/javascript">  
    function init(s) {  
        var isChrome = /Chrome/.test(navigator.userAgent) && /Google Inc/.test(navigator.vendor);  
        var createFrameElement = s.printHelper.createFrameElement;  

        s.printHelper.createFrameElement = function (name) {  
            var frameElement = createFrameElement.call(this, name);  
            if (isChrome) {  
                frameElement.addEventListener("load", function (e) {  
                    if (frameElement.contentDocument.contentType !== "text/html")  
                        frameElement.contentWindow.print();  
                });  
            }  
            return frameElement;  
        }  
    }  
</script>

DevExpress.Web.v14.2, Version=14.2.3.0

Thanks,
Jen

Hi Jen,

In the code you provided, I see that the client-side event handler's script block seems to be defined below the ReportViewer control's definition. Note that the client-side function should be already declared on the web page above the DevExpress control where you use it. Check the Client-Side Events help topic for more information on how to handle client-side events.

So, move the <script> tag to the top of your web page or to its <head> section.

Do you have any ideas on how we can improve our Reporting products to make them easier to use in the context of your applications? Maybe you have some feature requests?

Your feedback will help us make our products better.
