Items in combobox not showing

Posted on by Mikkel1976

I have a form where I have several combo boxes (modern control).

The items in these comes from choice columns in Dataverse.

The problem is that first time the form is loaded the items are empty.

If I then navigate to another screen and back to this screen then the items show.

If I add a classic dropdown (as in the top of the screenshot) the items in this shows perfectly.

Anybody have the same issue or knows if it's related to the modern combo box?

The items are populated like this in the attached example:

Choices('Forretningskritikalitet (WA-MasterPowerApp-Stamdata)'))

hey @Mikkel1976

i guess your defaultselecteditem is empty.

can you check and either set Parent.Default or ThisItem.ColumnName.

Exchange ColumnName with the name of the column.

Let me know if my answer helped solving your issue.

No, the Defaultselecteditems is not empty. So that's not the problem 🙂

As I said after navigating to another screen and back the issue disappears.

hey @Mikkel1976

thanks for your reply. maybe the refresh function will help? Did you already try? Refresh(Yourdatasource)?

besides that many of the modern controls are still in preview and can be buggy. did u try with a normal combo box?

I have a Refresh of the data source on the OnVisible of the screen.

Yes, maybe I'll try to use a classic combobox where I need to select multiple values and use a dropdown where I need to only select one value 🙂
