    I have many reports built in a prior version of Telerik Reporting, and have since upgraded to Q2 2010.  In trying to build a new report I am having a problem with specifying the DataSource for the chart as well as the chart's report parameters.

    I have several existing DataSources defined in the project, but in my new report when I click on the pulldown button for DataSource, none of these existing DataSources are available for selecting.  The Current Data Sources and Project Data Sources lists are empty.

    Not sure what I might be doing wrong.

    Hello Dan,

    If you have upgraded from version older than Q1 2010 where we introduced our Data Source Components, then you're probably using dataset as data source. For backwards compatibility reasons Telerik Reporting supports binding directly to IEnumberable/IListSource objects (incl. arrays, collections, DataSet, DataTable, DataView, DbDataAdapter), however you would not be able to select them as data source from the Report Designer, and if they were selected prior the upgrade, they would still be used as data source. For version after Q1 2010 consider using the ObjectDataSource Component that can handle this types of data sources.

    All the best,

    Ok, thank you.

    While on the subject of new version Reporting vs old version Reporting, the other major issue I have found is this.  In the new version when you add a chart, it does not have a selection for Skin.  By selecting a Skin in the old version, it would provide a set style of chart that one could use over multiple charts.  With this missing in the new version, it is very difficult to match up  the style of a new chart to an old one.  Why no Skin choice?

    Hello Dan,

    This was a bug immediately addressed in the Q2 2010 SP1. Please always upgrade to the latest version of the product prior reporting a problem, in order to avoid reporting already fixed problems.

    Thank you for the understanding.

    All the best,

    Thank you for the reply.  I just updated to Reporting Q3 2010 SP1 (and also RadControls for ASP.NET AJAX Q3 2010 SP2).

    Now when I run my Telerik Reports I am getting an empty ReportViewer control containing the message "Entry point was not found."  The project compiles ok.  Any ideas?

    Hello Dan,

    This is a generic error and usually means that there could be a binary mismatch in your referenced dll and the actual one used. Most likely you have not uninstalled the previous reporting installations and have mismatched references. Please use the Upgrade Wizard to upgrade your projects containing Telerik reports and rebuild the project. If you have added manual references i.e. Copy Local = True, then delete all assemblies from bin folder, re-add proper references in the project and rebuild the project after that.

    All the best,
