Hi to everyone,

I'm receiving the following error while trying to preview a report (created with a previous version of Telerik Reporting) using the current version (Q3 2010): "Error: The Expression contains undefined function call LeafNumber()".
The report (created in VS2010) gets its data from a stored procedure: I used the profiler, and the SP on SQL Server 2008 R2 is correctly called from within the preview page, the data is returned correctly, but I always get this error.

Prior to upgrade there was no problem in displaying the report.

I tried to search in the forums "leafnumber" but I found no result.

Could you please help?
Thanks in advance.

Hi Dan,

This function (LeafNumber()) is used internally by some of our built-in functions e.g. RowNumber/ColumnNumber, but we have not been able to reproduce the error on our end. We would appreciate if you provide us with the expression which causes the error or even better attach a runnable report that exhibits the problem. Once we review it, we would be able to provide you with more information about the culprit.

Regards,
