Boundary Conditions in PDE

I have a problem with defining boundaru conditions id NDSolve 
of PDE
F is function of [x,t] 
Conditions has form : (d/dx)F[0,t]==0;

I wrote this in form : D[F[0,t],x]==0 
Its TRUE  (0==0)

Then i wrote D[F[x,t],x]
out: F(1,0)[x,t] ;    {(1,0) looks like "power"}

And "copy"&"paste", and changed x to 0 in arguments

This way works, but I'm sure is a better way ? 

Regards, Olaf
