Hi,

    I'm new to the Telerik scene, and I'm having an issue with creating my first sample report using Telerik Reporting.

    I created the class for the report, and I am in the wizard for what data to get and view.....

    I'm connecting to a MySQL database, and I have the query built in the query builder... and in this query builder the desired output is attained....

    when I go to the next section, the Preview Data Source Results.... whenever I click Execute Query... I receive the following error:

                                 Number must be either non-negative and less than zero or equal to Int32.MaxValue or -1.
                                 Parameter name: dueTime

I never accessed or set anything related to that parameter... I don't even know what this issue is referring.... that's why I'm asking for help.

what do I do to resolve this?


Thanks,
    Amit

Hi Amit,

Thank you for elaborating.

Currently we have a known issue that slipped into the Q2 2010 related to MySQL ADO.NET provider that causes "Object reference not set to an instance object" error to occur. The problem is related to the CommandTimeout property of the MySqlCommand class that might throw NullReferenceException under certain conditions. For now you can revert back to the previous Q1 2010 SP1 release until we provide a fix to this with an upcoming internal build.

As for your exact error, please send us your Select statement, SQL Tables' definition and the report to investigate the issue locally.

Please, excuse us for the temporary inconvenience.

All the best,
Peter
