Answer 1

It seems like a format versioning issue. Can you view the report properly directly on SSRS (without the control)?

If so, it probably means that you need to upgrade your ReportViewerControl in your application - VS 2010 has version 10 of the control.

If not, it may mean that the RDL uploaded to SSRS isn't the correct version for your server.

Edit You haven't stated whether your app is web or windows - I've assumed web. What might have happened is that you upgraded your project from VS2008 and it is still referencing V 2008 of the ReportViewer control?

Check your app's web.config

Under <system.web><compilation><assemblies>

<add assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
<add assembly="Microsoft.ReportViewer.Common, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

Under <system.web><compilation><buildProviders>

<add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.Common, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

And you need to make sure that your web project has a reference to v 10 of Microsoft.ReportViewer.Common and Microsoft.ReportViewer.WebForms , and it is set to deploy to your bin directory.

Edit2

VS2010 uses Ajax - add in a ScriptManager to your page before the ReportViewer control, or just paste in the following:

<asp:ScriptManager ID="scmForReportViewer" runat="server">
</asp:ScriptManager>
