How to set default value of Boolean parameter false in SSRS?

Question

I have 18 Boolean parameters in my report. I want to make their default value to false through expression when ever user runs the report.

I am trying this but its not working

=SIDIdNum.Value = "false"

Getting Error: parameter SIDIdNum caontain an error [BC30451]

Answer 1

Have you tried just...

false

I'm also not sure where you're trying to set this value? If you are accessing the parameter from somewhere other than parameter properties dialog, you'll need to use

Parameters!SIDIdNum.Value="false"
