Question

I am working on VS2010, Crystal Reports. While compiling my code I am getting below error:

Unknown server tag 'CR:CrystalReportViewer'

I have added reference in the web.config file as:

    <assemblies>
            <add assembly="CrystalDecisions.CrystalReports.Engine, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
            <add assembly="System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
            <add assembly="System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
            <add assembly="CrystalDecisions.Shared, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
            <add assembly="CrystalDecisions.ReportSource, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
            <add assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
            <add assembly="CrystalDecisions.Enterprise.Viewing.ReportSource, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692FBEA5521E1304"/>
< /assemblies>

In my aspx page i have registered following:

< %@ Register Assembly="CrystalDecisions.CrystalReports.Engine, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.CrystalReports.Engine" TagPrefix="CR" %>

< %@ Register Assembly="CrystalDecisions.ReportSource, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.ReportSource" TagPrefix="CR" %>

Could you please suggest what i am missing?

Answer 1

I think you only need to register this guy…

<%@ Register assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" namespace="CrystalDecisions.Web" tagprefix="CR" %>

that and make sure you installed the VS 2010 version of crystal. It doesn’t come with VS anymore…
