Match portal row to layout record

[michelserres]

Hello --

I'm trying to setup a layout where I have a portal showing all records of, say, "classes". In this portal I need to match the current record of the layout to the row's record.

all_classes is a cartesian product of class:

class::id x all_classes::id

I defined a field in class called "__is_current" as

If(id = all_classes::id; 1; 0)

Problem is now that the rows only match the first class record, not the currently shown.

Example:

Viewing class id 1, the portals reads:

all_classes::id | id | __is_current

1 | 1 | Yes

2 | 1 | No

3 | 1 | No

Viewing class id 2, the portal reads:

all_classes::id | id | __is_current

1 | 2 | Yes

2 | 2 | No

3 | 2 | No

while it *should* read:

all_classes::id | id | __is_current

1 | 2 | No

2 | 2 | Yes

3 | 2 | No

Am I doing something wrong or isn't this possible with Filemaker?

Thanks for any hint

What is the purpose of this calculation? It's not really possible because there is no 'flag' to mark the current record in a table (there could be multiple 'current' records in multiple windows, for example). It's more of a window/layout thing - and you CAN highlight the portal row showing the current parent record, using conditional formatting.

Thanks already,

in my real database I'll return a colored pattern from a global media field to highlight the portal row showing the current parent record, as you said.

Just having a blackout, but how to write the condition for the conditional formatting?

Sorry, I haven't noticed your version before. I'm afraid we have a misunderstanding: you can do this quite easily using version's 9 conditional formatting, but you cannot do this using calculation fields alone.

To use a calculation field as you want, you will need to use a variable that will be evaluated on screen refresh - see the attached.

Hi comment,

The file doesn't not have a CF, and the formatting doesn't show in 8.5 of course.
