I’m trying to display an RDL report using the ReportViewer control. I already managed to load my report with some help of SO. But now i’m facing another problem.

The report is loaded, because it shows all the parameter textfields of the report. But when i fill those in then no report results are shown. The exact same params do work when i view the report in my web browser through the ReportServer URL.

I think the problem is because it also displays this error on my ASP.NET page (where i have the ReportViewer control).

Your browser does not support scripts or has been configured not to
allow scripts.

Which is weird, because every other javascript enabled site works perfectly fine for me. I believe this error is thrown because i have a ScriptManager in my ASP.NET page.

I have no idea how to fix this problem. Anyone any idea how to solve this problem?

NOTE:

The error does not appear when i remove the ReportViewer control. I can also execute an alert in a <script> tag. So JS seems to be working.

This is what i have in my page:

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <h2>Report</h2
    <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" 
        Font-Size="8pt" Height="742px" InteractiveDeviceInfos="(Collection)" 
        ProcessingMode="Remote" WaitMessageFont-Names="Verdana" 
        WaitMessageFont-Size="14pt" Width="907px">
        <ServerReport ReportPath="http://server.com/Product/Dashboards/Product_tool.rdl" 
            ReportServerUrl="http://server.com/ReportServer" />
    </rsweb:ReportViewer>

    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
</asp:Content>

And in my PageLoad:

ReportViewer1.ServerReport.ReportServerCredentials = new ReportCredentials("user", "pass");
ReportViewer1.Visible = true;
ReportViewer1.ServerReport.Refresh();

    The most likely cause for this is that the site is on an address that isn’t trusted. Internet Explorer opens sites in zones, and it may have put your development address in an untrusted zone, which disables scripts by default. You can usually see an icon somewhere that indicates this and allows you to add the address to the trusted zone.

    Look for an eye icon or a warning icon – depending on the version of Internet Explorer you are using.

    You could also fire up another browser and see if it is any different.
