Subform calling main form

sabzam

Dear All,

Can a subform in some way or another call the main form?

crisnicolas

sure yo can... just create a variable of type form, pointing the form you want, and call it's functions or run it... but... it will be a different instance of the form...

I don't know if your question belongs to NAV Three Tier but take a look at this topic http://www.mibuso.com/forum/viewtopic.php?t=22564.

Or you could try by SendKeys explained in this topic http://www.mibuso.com/forum/viewtopic.php?p=136085.

That's the issue I need to call the proper form rather than just the form of the main form. Therefore I need something of the sort currform.(subformname).form.(function). This can be used for the main form to call the current subform but I do not know how I could get the same thing the other way round.

The only way I know is to use a singleinstance codeunit and RUNMODAL for the form. But in that case you can't use NAV until you closed the form.

Perhaps you should think about redesign your application.

Or you could use the OnTimer trigger on the main form to call a function on the subform every few ms.
Or move all the code from the form to a single instance codeunit, and use it from both the main-form and sub-form. (But then you should ensure the main form is only open once or be able to support it)

Depends what you are trying to do...

are you trying to update a header with a value from the line?

Actually I need to trigger a function onto the main form once a record is modified in the subform.

Obviously you're working on classic client, don't you? Then I think you have to redesign your application. A function on a main form that has to be called by a subform isn't a proper application design. And you have to bear in mind that in future (RTC) you won't have any function on GUI.

Move the code to the table in the sub form and have it triggered there.
