Hi Pal,
i did the same way but as i said i'm using .net 2.0's dataset which
seems doesnt understands the view. As i've added "Enforced Constraints"
in the Dataset, may be that could not allowed the View to be considered
with foriegn key, unique value, not null constraint.

to avoid this situation i need to some other way. and yes it is true.
i'm reffering it in more then 20 webpages so i cant modifiy it.

anyways thanks for help.
