Disabling a Tab

Hi Folks,

I have a requirement where i need to disable a tab based on a condition. i have binded the Tab property VISIBLE to a context structre which holds the value to disable the tab. But it does not work. I tried passing values like NOT, 02, NO and 00 it did not work.

Can anyone suggest me if iam doing the right way or do i need to pass anyother value.

Thanks.
