Hi,

I have an app where there is a Gallery of CDS Data Source "Questions". Each record of Questions is have different "Answers" record.

I have used combo box to show all the records Answers record related to the particular Question.

When the user selects the Answers and clicks on Next button, I am collecting the Question and the Answer in a Collection.

But when the user selects the Back Button, it should show Previous Questions with selected Answers.

This is the Collection for Collecting the Question and Answer Records:

ForAll(
 SelectedQuestions,
 Collect(
 saveQuestions,
 {
 Name: SelectedQuestions[@Name],
 GroupId: SelectedQuestions[@Group],
 QuestionId: SelectedQuestions[@Question],
 answerRecord: SelectedQuestions[@selectedAnswer]
 }
 );
 
);

On Selecting the Back Button the Combo Box should show the Selected answers but I am struggling to get the selected Answer

Any help is appreciated.

Hi @tjalui ,

Do you mean that:
1)you select one item in the gallery of Questions?

2)then you display related answers based on this selected question?

3)if you click the "next" button, you will create a collection with selected question and selected answers?

4)if you click the "back" button, you want to display related answers based on selected question's Previous one in that answer combo box?

If so, could you tell me:
1)the formula about how to create SelectedQuestions?

2)the formula about the answer combo box's Items?
3)the relationship between Questions entity and Answers entity?

4)what do you exactly mean about "Previous Questions"?

I assume that:

1)Questions entity and Answers entity relationship is: 1:N, Answers entity has a lookup field named answer(looks up to questions entity)

2)SelectedQuestions is the gallery's selected Question

3)"Previous Questions" means the question before the selected question

If so, you could set like this:

1)galleryquestion's OnSelect:

Set(SelectedQuestion,Galleryquestion.Selected.Name)

2)back button's OnSelect:

Set(SelectedQuestion,LookUp(Questions,ID=Galleryquestion.Selected.ID-1,Name))

3)the answer combo box's Items:

Filter(Answers,answer.Name = SelectedQuestion)
