Can't get ComboBox DefaultSelectedItems to work

Posted on by HJ-23070237-0

I have this Named Formula:

IdeaBenefits = ["","Montary Benefits","Customer Service","Improved Morale","Improvement of Organizational Communication","Safety/Health","Working Conditions","Improve Consumer Outcomes","Process Improvement","Product Improvement","Reduce Paperwork","Other"];

The ComboBox Items property is set to:

IdeaBenefits

The ComboBox DefaultSelectedItems property is set to:

If(
    IdeaFormEdit,
    Filter(
        IdeaBenefits,
        Value in Split('List Ideas Gallery'.Selected.'Potential Benefits', ";")
    ),
    []
)

(Each "Idea" can have multiple benefits so this is a multi-select ComboBox)

All the other controls are working perfectly, just the one ComboBox is not. Nothing becomes selected when it should be.

For an example, when I put 'Potential Benefits' into a simple text label for a particular Idea, it shows "Montary Benefits#;Customer Service#;Improved Morale#;" (idk why the last dev added the hashes, I did try adding that in the split delimiter but it still didn't work.

Any ideas?

Hi @HJ-23070237-0

Since we cannot see what the value of 'List Ideas Gallery'.Selected.'Potential Benefits' is, its easy to say thats the issue but let's take it further

Add a second gallery or a list or a combobox I dont care

Assuming that 'List Ideas Gallery'.Selected.'Potential Benefits' produces a collection of Strings, again strings, if you just put your split function in its items property what do you get back?

Next,

I'm not sure I would have used a named formula for essentially a collection but hey :-) thats up to you, but thats just me.

Or

instead of doing your split you could do concat which will just create a string, and then the in fill find it assuming Value is coming out what you want (meaning) the individual items in IdeaBenefits

Concat and Concatenate functions - Power Platform | Microsoft Learn

So that you are checking the string alone versus trying to do essentially a contains for an array of things you get back.

If(

  IdeaFormEdit,

  Filter(

IdeaBenefits,

Value in Concat('List Ideas Gallery'.Selected.'Potential Benefits', Value & "")

  ),

  []

)

Thanks for the reply Michael. With this new horrible forum I hope you see my response, I can't tag you or reply to your comment.

So I selected an idea in the gallery and the put "'List Ideas Gallery'.Selected.'Potential Benefits'" in a textbox and it gave me "Montary Benefits#;Customer Service#;Improved Morale#;"

As per your suggestion, I added a combo box and made the Items property "Split('List Ideas Gallery'.Selected.'Potential Benefits', "#;")" and then it did correctly show the items that were selected for that selected Idea.

However in that new ComboBox if I set DefaultSelectedItems also to "Split('List Ideas Gallery'.Selected.'Potential Benefits', "#;")", it still is selecting nothing, even though we now know that formula is returning valid results.

Using concat changed nothing.
