Hi Community,

I have this scenario that i need to add the values of the selected checkbox in the combobox (Type: Choice / SharePoint list / Multi selected enable).

To give more details on this, i have a SharePoint list with the field type of "Choice" and the choices values are example. 1. Choice 1 / Choice 2 / Choice 3 / Choice 4). - See screenshot below

Now, what i need is, IF the user selected any of the checkbox below, i wanted to add those choice values in the combo box. (my idea is automatically adding /selecting / filtering the combo box value in the app. Remember both Check box and Combo box has an exactly same values.

If i uncheck the "Choice 2", it will also deselect / remove in the combo box.

Is this logic possible? Please help. thank you in advance

Hi @echodapogi ,
I tried from my end and this what you can do:

First add checkbox in gallery and the item property of gallery and combo box item property make it like below

Choices(TESTING.Keywords)

TESTING is my SP list where Keywords is choice column.
Then for combo box DefaultSelectedItems property put this code:

Filter(Gallery3.AllItems, Checkbox2.Value = true)

Gallery3 is a gallery where i have added the checkbox.

This should work for you but only in one direction, I mean if you check or uncheck the checkbox, then it will remove or add the value in/from combo box.

I hope this helps.

Hello,

Might I ask why you would want to do that(lol I am curious).

Ok, let me validate a couple things.

1. What values are in the ComboBox when the screen first loads?
2. When you load do you autoselect the checkboxes then?
3. What is the difference between the dropdown and the checkboxes as it relates to the user experience

In the end, are you writing the .SelectedItems from the ComboBox back to SharePoint?

So yes, you could filter. You would have to do something like this.
But it's a little weird because filtering a Single choice is easy but filtering a multichoice requires you to convert to Text and it's just ugly.

Are you sure you really wanna do this hehe

Cheers

Hi FLMike, I have a weird and unique business requirements. To give you an idea, i will be implementing this logic in a dynamic wizard form like app. The business requirements is to create a series of question with the checkbox / radio box as the selected components in the form. but when you create a edit form in powerapps, it automatically selects combo box on the choice field in sharepoint. so i need to display the selection in a checkbox but the same time adding it to the edit form to save. weird case scenario but i think the idea above will work.
