    Hi Frank,

    Such error can occur in the VS Report Designer, if the project uses Telerik Reporting version different than the installed on the machine.
    Please check if you have Telerik Reporting installed on the machine, if the IDE covers the minimum system requirements, and finally test running the Upgrade Wizard.

    I hope this information is helpful.

    Do you want to have your say when we set our development plans? Do you want to know when a feature you care about is added or when a bug fixed? Explore the Telerik Feedback Portal and vote to affect the priority of the items
