Getting Javascript error with: $ create (Microsoft.Reporting.WebFormsClient.ReportViewer

Question

We have a report viewer and it adds the following jscript to the aspx file:

//<![CDATA[
Sys.Application.add_init(function() {

if (typeof Microsoft == 'undefined' ||
    typeof Microsoft.Reporting == 'undefined' ||
    typeof Microsoft.Reporting.WebFormsClient == 'undefined' ||
    typeof Microsoft.Reporting.WebFormsClient.ReportViewer == 'undefined')
    Sys.UI.DomElement.setVisible($get('ReportViewer1_HttpHandlerMissingErrorMessage'), true);
    $create(Microsoft.Reporting.WebFormsClient.ReportViewer, {"_internalViewerId":"ReportViewer1_ctl03","id":"ReportViewer1"}, null, null);
});

But it keeps showing the script error “Microsoft is undefined” when it gets into

$create(Microsoft.Reporting.WebFormsClient.ReportViewer

lines. We just upgraded from Silverlight 3 / VS2008 to SL4 VS2010 - is there something missing?

Answer 1

I get the same error. I followed the instructions at http://otkfounder.blogspot.com/2007/11/solving-reportviewer-rendering-issue-on.html but this did not solve the problem and I still get the error. Give him a chance, but it might work for you ...
