I have a Sharepoint list in which I am storing information through a form created with the help of PowerApps, I am presenting the problem that I want to display the values saved in a Listbox in the view mode, the Listbox I have activated Allow multiple selections, since I require it.

That is, when selecting a Sharepoint Item to see its information does not show me in the listbox the values that it has registered.

It is important to make it clear that items in the list box are obtained from a search column in Sharepoint.

In the Default property of my Listbox I have set the value "1", I don't know why.

In the Items property of my Listbox I have defined the following, where I refer to the Sharepoint list column.

Is there any way in which you can display the items previously saved in the listbox but in the view mode ?

Although a listbox will allow you to make multiple selections, it will not allow you to select multiple items through the default.

If you only had one selection to be shown, then it would be fine, but for multiple - it will not work!

I would recommend not using the ListBox control if you need to select multiple items in this case.

I hope this is helpful for you.

That is great! But, like I mentioned, you can use a listbox and select multiple values just fine - but you cannot set the multiple values to be displayed by default in the listbox control. It just doesn't do it.

@RandyHayes Ok, I understand that I can't use Listbox to display multiple values, that another component I can use to display items previously saved in the Listbox

If you want the ListBox "look", then a Gallery is a good choice.

I typically do that Listbox lookalike in a Component and then use it in place of the ListBox.

@RandyHayes I'm not really interested in the same aspect of Listbox, what interests me is that the values that were previously saved are displayed, could it be that it is displayed so in a TextInput and separated by comma, some idea ?

Yes, you can always do that. I thought you wanted to have a ListBox show the values that were selected.

It is actually kind of important that they do show what is selected as you will otherwise run into complexity if writing the data back. Meaning, if someone edits a record that has a listbox of data shown and yet they make no changes to that listbox selection, then by default, if you write back the listbox choices...well, there will then be none, and your data will be lost.

If you just want to display the values, then it depends on your column type. I will assume it is a choice column and that you have multiple selections enabled on it.

In that case, a label or textinput with a formula such as : Concat(yourColumn, Value & ", ")

Again, depending on your scenario, but that would show the choices.

@RandyHayes The type of column in the Sharepoint list that I am using is LookUp, would it work the same in this case ?

Yes, the Lookup column has a Value property as well. It would be the foreign column value that is defined in your lookup column settings in the SharePoint list.

The formula Concat(yourColumn, Value & ", ") in which property of the label or text input is added ?
