InfoPath Dev

In my browser-enabled form (InfoPath 2007), I have an Optional Section control I want to show/hide selectively using code-behind.  In a client-only form, I understand this can be accomplished by calling the ExecuteAction method on the control.  Is there an equivalent for browser-enabled forms?  Thanks.

ExecuteAction is not supported in browser-enabled forms. A work around for your problem may be

1) have an additional field(say is_opt_sec_visible) in your form.

2) place conditional formating on optional section if is_opt_sec_visible = "1". hide the field.

3) In the code decide whether the optional section needs to be shown or not. if yes set the value of is_opt_sec_visible to 0, otherwise set is_opt_sec_visible to 1.

 I was able to do what I needed without code.  However, for those who must use code, what you suggest seems like a good workaround to the problem.  Thank you.

you had mentioned programmatically that is why is used the code
