Hi Syed,
Is isPaid a bool in your code?
If yes then it cannot be null, unless you defined it as "bool?".
If it is a bool and not a bool? then you probably got a warning message at build like this:
"The result of the expression is always 'true' since a value of type 'bool' is never equal to 'null' of type 'bool?' "
Otherwise I think it should work as you did. I did this way many times before and it always worked.
If it is not the case then let us know.
Regards, Peter
