TextBox Fill Changing Unexpectedly

(0) Share

Posted on by Justair07

Hello,

I have an app with a gallery of 39 questions. The expected behavior is for the Fill of the question TextBox to change based on the selected value of a Radio Button.

The issue, when I test, for the first few questions I answer, it works great (green for pass, red for fail) as you can see in my first picture.

In the second picture you can see how some of the questions start to turn green even without me selecting anything from the Radio Buttons (question 7).

I've tested this out in the following ways:

Chrome
Edge
Clearing the browser cache
Windows PowerApps Desktop
iPhone
PowerApps Studio

All of my testing results in the same issue. I can't seem to find a consistant pattern of the issue either. sometimes it starts to behave weird after 5 questions, of sometimes after 10 questions. Green or Red, it doesn't matter.

I thought this behavior was very weird and was hoping that someone has had a simular issue and resolution. Maybe I'm doing something wrong all together.

Thank you in advance to anyone who can shed some light or guidence on this.

- Justin

@Justair07
I think there are multiple Radio fields and you passed the refrence of only first field which has the name of ARadio.

Please check.

Hi @panand99,

I have only one radio field but it is in a gallery. I'm beginning to think that this is a PowerApp limitation. 😞

The screenshot with all green boxes looks a bit odd. Why is the selection box not lined up with the green box?

Thanks
Luke

I realised it was a gallery and it's the initial question box location.

Have you got a default value set in the radio control? Is the control linked to a data column?

Update:
With the help of @faustocapellanj , we were able to come up with a solution to achieve the desired effect.

We created a collection that stored the unique ID of each item in the gallery and also stored the result from the radio box. There is an IF statement to first determine if the radio button has already been changed, if it has, when it is changed again, Patch the new result to the collection, if not, simply store the ID and result in the collection. Here is the code for the OnChange feature for the radio button:
If(IsBlank(LookUp(colRadio,QuestionId=ThisItem.IdQuestion)), Collect(colRadio, { QuestionId:ThisItem.IdQuestion, PassFail:ARadio.Selected.Value } ), Patch(colRadio, { QuestionId:ThisItem.IdQuestion }, { PassFail:ARadio.Selected.Value } ) )
and here is the code for changing the Fill on the label:
If( LookUp( colRadio, QuestionId = ThisItem.IdQuestion, PassFail ) = "Pass", RGBA(0,230,64,.7 ), LookUp( colRadio, QuestionId = ThisItem.IdQuestion, PassFail ) = "Fail", RGBA(207,0,15,.8), RGBA(0,0,0,0) )
Don't forget to clear the collection upon exiting the app.
Thank you!
