Reports IN NAVISION 2009 SP1 RTC

Hi everyone,

I am working on reports on RTC, I am done with everything but when i write section code in the Visual Studio in the visiblity option. That is not working.

AN Example of that is i put a visibility expression for a section as

"=IIF(Fields!Work_Order_Line__MA_No__.Value <> nothing,true,false)"

but its not working.

Please explain what this expression means and how will it work.

Thanks in Advance

write this instead of above statement…

“=IIF(isnothing(Fields!Work_Order_Line__MA_No__.Value),true,false)”
