I have a section in a Crystal Report that I want to suppress. I need to suppress it if there are 0 rows in a particular table in the dataset I am using. How would I do this? The Record Number special field provided appears to be an internal count of records in the report, and does not relate to the rows in the underlying data table.
I am creating the report from C#, but I cannot suppress the section from the code (it doesn't fit the project structure) - I must be able to do it from the report itself. The table concerned is definitely being passed to the report in the dataset, but it contains 0 rows. There must be a way to establish this inside the report itself.....
Can anyone please point me in the right direction?
In the Crystal Reports designer, view the properties of your section and there should be an option to Suppress, which you can give it a formula to return the appropriate boolean value.
You could then use the Count() function within that formula and (I believe) you can pass the name of your dataset to the Count() function to get the number of rows in that dataset.
I did the same thing on a complex report about 3 months ago but I don't have access to the report any more having changed jobs so I'm sorry I cannot be more specific, but hoepfully this gives you a starting point.
Just had a quick Google - try this.
