I have a requirement to hide tablix based on condition
in the properties of tablix I am using below
=iif(Fields!ClosedDate.Value<"2015-07-01","True","False")
whenever ClosedDate is less than 2015-07-01 I want to show tablix to load data into report. whenever ClosedDate is greater than 2015-07-01 I want to hide tablix to load data into report
but when I am doing preview I am seeing error "the hide expression used in tablix 'Tablix2' returned a data type that is not valid"
please can anyone suggest what is the error in the expression?
