Hi,
I have a form that supposed to not let user to submit until the relevant fields have been filled up. Let me picture a clearer context on this situation:
General Field: Field A (text), B (text), C (text), D (lookup dropdown) are compulsory to be filled/ selected.
The lookup dropdown Field D let users to select a certain 'Instrument' and based on the instrument other fields E, F, G, H will be show/ hide based on the selected 'instrument'.
Example: 'Instrument 1' selected - Field E show
'Instrument 2' selected - Field F show
If Instrument 2 is selected, Field E will be hidden and user don't need to fill it up.
My current formula only able to disable the submit button if the general field A, B, C, D are not filled up. I tried to fit in the rest of the Field EFGH, but I realized using && or || doesn't work for these non-general field. Is there any other way that I can disable them?
Here's a sample of my current formula:
Share
ReportIf(!IsBlank(A) && !IsBlank(B) && !IsBlank(C) && !IsBlank(DateValue2_1) && !IsBlank(D.Selected), DisplayMode.Edit,DisplayMode.Disabled)
Thank you.
Hi,
The solution worked initially but after some time I guess powerapps confused with it and the button displaymode doesn't disabled anymore. I tried to nest the logic but it still doesn't seem to work. Can anyone help me to see if I nested it correctly or if I make a mistake in the logic?
Thank you.

I think @Pstork1 approuch is excellent, but it can be difficult for beginners to extend. I got some time, so I did sort out Your problem. I hope this is what You are looking for.
Here is the code I used for the button :
If(
(!IsBlank(A) && !IsBlank(B) && !IsBlank(C) && !IsBlank(D.Selected.Value)) && (D.Selected.Value = "Instrument 1" && !IsBlank(E)) || (D.Selected.Value = "Instrument 2" && !IsBlank(F)) || (D.Selected.Value = "Instrument 3" && !IsBlank(G)) || (D.Selected.Value = "Instrument 4" && !IsBlank(H)),
DisplayMode.Edit,
DisplayMode.Disabled
)
And here is the Code I used for the visibility of buttons :
(D.Selected.Value = "Instrument 1")
Make sure to change numbers based on control from Instrument 1 to 2, and so go on.
Hope this helps
The problem with that approach is that emptyFields is a running count so you can't just change it to an arbitrary number. Instead you'll need to add or subtract the number of empty fields being made visible/hidden by whatever selection you make.
Thank you @Pstork1! Can I set condition for the number of counts on the button depending on the number of fields appearing based on the instruments?
Assuming the total emptyField = 25,
In Instrument 1, there will be 15 emptyField
In Instrument 2, there will be 9 emptyField
I tried to set the button to something like this but it came back with error.
If(D.Selected.Value= "Instrument 1", (emptyFields <= 15, DisplayMode.Edit,DisplayMode.Disabled)
@cha_cha Thanks for your input! Tried the provided logic but it doesn't work the way I wish it to be.
Example:
If Instrument 1 selected: Field E visible, submit button disabled until filled. (nice!)
If Instrument 2 selected: Field F visible, but submit button is disabled because of the condition set for Field E.
Hope this example could provide a better context of the current challenge I'm facing right now.
Here's the way it works
In OnStart and Screen.OnVisible
Set(emptyFields,<<number of empty fields on default screen>>)
In Each Control set OnSelect to the following to store whether the control is currently blank
UpdateContext({temp: IsBlank(Self.Text)})
In Each Control set the OnChange to the following to update the emptyFields count as each field is changed. This will add 1 to EmptyFields if the field is currently filled in and the value deleted. It will subtract 1 if the field is empty and filled in. If only the value changes, not whether its empty or filled in then the count won't change.
If(
temp,
If(
IsBlank(Self.Text),
false,
Set(
emptyFields,
emptyFields - 1
)
),
If(
IsBlank(Self.Text),
Set(
emptyFields,
emptyFields + 1
),
false
)
)
In the DisplayMode of the Button then its just
If(emptyFields <= 0,DisplayMode.Edit,DisplayMode.Disabled)
The one additional thing you would need to do is to change the EmptyFields count as additional controls are hidden or made visible based on the selection in the dropdown. You may also have to adjust the formula for different types of controls. For example, a dropdown you would need to check if the selection is different from the default since they're never really blank.
EDIT: Here's the code to add the extra fields to the EmptyFields count when the user picks from the dropdown. Where Instrument makes one field visible and Instrument2 makes two fields visible.
If(
Self.Selected.Value = "Instrument1",
Set(
emptyFields,
emptyFields + 1
),
false
);
If(
Self.Selected.Value = "Instrument2",
Set(
emptyFields,
emptyFields + 2
),
false
)
There are a number of formulas here, but its essentially the same set for each control and the formula on the button is always the same. So this can expand to cover as many controls as you need.
Can you please try this logic? I'm also keen on learning @Pstork1 on ways to this but would want to know if this kind of logic is possible.
If(
IsBlank(A) Or
IsBlank(B) Or
IsBlank(C) Or
IsBlank(DateValue2_1)
Or IsBlank(D.Selected)
Or (E.Visible And IsBlank(E))
Or (F.Visible And IsBlank(F))
Or (G.Visible And IsBlank(G))
Or (H.Visible And IsBlank(H))
