Part Functions not Available from Main Page?

Hi.

I have created a page with the source-table Item. In that page I have created several Groups, and within each a Part with Subtype Page. So far this seems fairly parallel to forms and sub-forms.

The main page has controls for date filters, etc. that I need to transmit down to the sub parts/pages. In a form this was easy - you added a function to the sub-form and called it from the main form.

I tried the same here - added a function to the "sub-page", but back in the main page when i bring up the Symbol Menu, under CurPage -> Controls I see the Group and the Page - but when I drill down into Functions for the page there are none listed.

Can I not call a function in a sub-page like I could with a sub-form?

If not, is there another way to transmit information to the sub-page?

Thanks!

    I got it.

    You have to create a variable of type Page with the subtype the (sub) page you want to configure. The functions of that page are then available through that variable.

    That approach will work, except when you specifically need to reference something from that particular instance of the sub page. There is a strange syntax (as of NAV 2009 R2) that you can use to access the exact sub page instance set in your main page (think pagepart in a factbox, where you need to set or access a variable or function that applies to the instance running within your main form).
    CurrPage."NameOfSubPageInstance".FORM."FunctionName";

    Note the call to .FORM (even though we are talking about a page).
