Reporting Services Expression -

-

i'm trying set hidden-property of textbox based on expression:

=iif(isnothing(parameters!customer_numbers.value) ,       isnothing(parameters!country_codes.value),false,true)

error: "argument not specified parameter 'falsepart' of public function iif(expression boolean, truepart object, falsepart object) object"

i'm jscript/c# guy , not used pseudo-vb language. wrong?

regards alex

my answer nothing wrong!

i created test report (rs 2008) 2 parameters: customer_numbers , country_codes. set parameters text fields , nullable.

i added textbox text "both parameters null". set visibility expression via copy , paste question.

the report starts fine, , if set both parameters null see textbox. rdl of textbox turns out this:

 <visibility>       <hidden>=iif(isnothing(parameters!customer_numbers.value) ,   isnothing(parameters!country_codes.value),false,true)</hidden>     </visibility>
