Using Microsoft Reporting Services, with local processing mode. Loading data sources and everything works nicely. What I would like, is to, in the the report definition, check if a certain value exist in on of the data sources. Is this possible? Like, if I have a data source with just one column of ‘Name’. Can I somehow check if the name ‘John’ exist among the loaded data?
The reason is that I would like to adjust some things if certain values exist. For example, if a certain value exist in that data, I would like to hide a column and adjust some widths etc.
Is this possible?
Use an expression like this:
You can put this in an invisible field somewhere, and then let the dynamic controls test on the value of the field.
