Hi Guys,

I have a label mapped to field in a database. If the field is empty then by default the label doesn't appear. (it used to return 'undefined' but since the builder update it returns "" instead), which is great.

How do I make a grid invisible if the same field mapped to a label is empty.

The label is in the grid so when there is no value returned I want the labal and the grid to not be visible.

Regards,
Joe

Hi Joe,

To manage visibility of label you should link from value to "Visible" attribute of the label.

See details: http://prntscr.com/4s9b32/direct

Also you can add "JS" like following:

pre

//return value == "";
return value != undefined;

/pre

Regards.

Hi Yurii,

I tried exactly as you said but it did not work, the grid is still visible when there is no value.

Hi Joe,

May be your rest service does not returns this field(not empty value)?

If so - please make link from parent object to "visible" label attribute and use following code:

pre

//Where "yourField" is your goal field.
return value.yourField != undefined;

/pre

Anyway if you can not to manage this problem please give us your app public link and describe steps reproduce this problem.

Hi Yurii,

i'm not sure that i understand you.

I have mapped it like this:

The grid contains 2 labels. with the text 'Venue tel:' and the other label is mapped to the 'VenueContact" field in the database".

my aim is so that if there is no 'VenueContact' number in the field then the grid wont be visible, hence the labels inside wont be visible too.

I tired the two codes and a combination of both but I can't see to get it to work.

I would prefer not to post a public link on here, shall i send it to you another way?
