Force RenderReport to return error

[Michael Love]

I have a pdf report that I am creating programmatically behind the scenes and I want to NOT create the report at all if there is no data.

I saw that RenderReport returns a result and I want to know if I can check to see if I get any rows in my NeedDataSource event handler and return and set an error there to have the PDF not be created.

Has anyone addressed a similar issue?

Actually, a better way is probably to check the data source results prior to rendering the report.

If no rows, then no report.

Anyone have a better idea?

1. I created a ReportBase that inherits from Telerik.Report and added to it a HasData property.
2. Then I have all my reports inherit from the ReportBase.
3. When I get the data in the report I check if there is any data, if no I set the property to false and return (without rendering the whole report).
4. Then after calling the RenderReport I check the HasData property of the report.

That is a great idea!

Thanks.
