In an ssrs 2008 report, there is the following IIF expression on the visibility property of a tablix:
=iif((CountRows("SrvyRespondents") < 1 ), True, False).
The "SrvyRespondents" is the name of the dataset that is accessed by the tablix.
Somehow the true and false portions determine if the tablix will display or not.
Thus would you tell me what the iif statement means? Would you tell me what each part means so that I know what the expression means in the future?
