Retrieving Multiple Columns from Single Record

Posted on by MitchellH

I am new to Power Apps and am trying to create my first application. I am running into a few issues though.

I am trying to create an app that identifies the user, grabs a random question from a database, give four possible answers, then records whether or not their answer was correct. I am able to confirm the user by their email and grab a random question, but trying to use the radio buttons for the multiple choice question is not working.

My database for the questions and answers is below.

My Formula for the Question Label is...

My Formula I am trying to use for the radio is...

I was wondering if any one could help me understand how to retrieve the four possible answer columns and place them into the radio. If it is possible, I would also like to randomize the order of the answers.

Also, if there is a better way to retrieve a question from the database, I am all ears.

Any help would be appreciated. Thanks.

The most simplest approach is to put the table on the Items property of the Gallery.
That way each row of a gallery will populate the possible answers

If you want to show one question at a time, filter The Gallery

Is there a way to do this without using the gallery? I would much rather be able to edit the questions from the excel doc and have it retrieve the questions and answers from there.

Thanks,

For you to be able to Use the Radio, the answer option should be in a column rather than a row.

The work around is to insert 5 textboxes:
1. Textbox1: QuestionID

2. Textbox2
LookUp (Questions,QuestionID=Value(Textbox1.Text), Correct1)

3. Textbox3
LookUp (Questions,QuestionID=Value(Textbox1.Text), Correct2)

4. Textbox4
LookUp (Questions,QuestionID=Value(Textbox1.Text), Correct3)

To move to the next question, you can Use the random formula to change the question numbers

Hi @MitchellH ,

Do you want to retrieve possible answers into a Radio control based on the chosen question?

Based on the needs that you mentioned, I think the Concat function and Split function could achieve your needs. Please try the following workaround:

Set the Items property of the Radio control to following:

Split( Concat( Filter( ShowColumns(Questions, "Correct", "Incorrect1", "Incorrect2", "Incorrect3", "QuestionText"), QuestionText = Label5.Text ), Correct & ";" & Incorrect1 & ";" & Incorrect2 & ";" & Incorrect3 ), ";" )

Note: I assume that the Label5 represents your Question Label.

If you also want to randomize the order of the answers, please modify above formula as below:

Shuffle( Split( Concat( Filter( ShowColumns(Questions, "Correct", "Incorrect1", "Incorrect2", "Incorrect3", "QuestionText"), QuestionText = Label5.Text ), Correct & ";" & Incorrect1 & ";" & Incorrect2 & ";" & Incorrect3 ), ";" ) )

Shuffle function

Please try above solution, hope it could solve your problem.

Regards,

Hi @MitchellH ,

I agree with @v-xida-msft . I have also written an article on a requirement similar to yours. I am using a SharePoint List instead of Excel. You should be able to do something similar.
