Empty people picker fields (not reset!)

Posted on by AndreaPRJ

Good morning everyone.

I am having this problem in this app where a user can choose a number of DEC needed. DECs are people, tied to single-choice People picker fields (comboboxes) .

Basically I would like that, once I have chosen the number of DEC needed (via the How Many field), the program automatically EMPTIES the unnecessary fields.

So if I select 4 dec, but then decide that I only need 2, the program should empty the fields related to dec3 and dec4.

I used the reset formulas in the OnChange event of the How Many field and the Default and DefaultSelectedItems formulas in the various fields related to DEC (percentage is a simple text field).

Everything seems to work: when I change the number of dec needed, the fields are emptied and when I save everything is ok in field's values.

The problem arises when I then reopen a saved record: the fields are ALWAYS empty!

I guess it's due to the DefaultSelectedItems and Default formulas: how should I set them?

Thank you

Hi AndreaPRJ,

I think what you mean is this (correct me if I am wrong)

1. When user will change the How Many from 4 to 3: Empty DEC4

2. But if they again select 4 in How Many (without saving): It should display the existing values?

Also, because you have emptied it once, when you select any other item, DEC4 doesn't display anything. Is my understanding of your issue correct?

I think in the DefaultSelectedItems property of DEC4, you need something like:

If(Value(HowMany.Selected.Value) = 4, [], ThisItem.DEC4Column)

Hope this helps. Let me know how it goes.

Kind regards,

Nandit

Hi Nandit

I probably hadn't explained myself well

I needed the fields to always be emptied in case either the DECs were not needed at all, or in case I had chosen a particular number of decs (2 decs necessary? then will you empty the third one, 1 dec only? then you empty me both dec 2 and dec 3)

in the end I did it like this and I solved : I removed HowMany DECs field, I left only the 4 thrash icons visible next to the 4 fields (always visibles) and in the onSelect of the icons I put:

for example for thrash icon for DEC1 fields:

UpdateContext({locResetControlsDEC1:true});Reset(DataCardValue_DEC1);Reset(DataCardValue_DEC1%)

and then in the DefaultSelectedItems of DEC1 People Picker field I put:

If(locResetControlsDEC1, Blank() ,Parent.Default)

I also added this in OnVisible property of my SharepointForm

UpdateContext({locResetControlsDEC1:false})

Start situation

End situation when I press thrash icon(s)

regards
