Struggling for a while on this one.

I want to set default values in Datacards on a dropdown. The choices vary, but are all either YES/NO or choices defined in lists.

The data is in a dataverse table 'Activities", for this example I will use the Column 'POReceived'.

Datacard: PORecieved_DataCard5

Control: DataCardValue41

Items: Choices('PORecieved (Activities)')

DefaultSelectedItems: Last(Choices('PORecieved (Activities)'))

It looks OK at first (red outline because I got an error on save):

But when I save I get an error, and if I click the dropdown, I see this (looks to me like it's really not selecting an item in the choices)

If I click the "X" it auto selects NO, and all is well.

Thanks.

Hi

What does your Update property look like?

Try and check these

Default Explicitly:

Use LookUp to select "NO" from the choices instead of relying on Last, which depends on order.

Updated Properties:

Items (Dropdown):

Choices('POReceived (Activities)')

DefaultSelectedItems (Dropdown):

LookUp(Choices('POReceived (Activities)'), Label = "NO")

Additional Checks:

Ensure the Update property of the DataCard (not the dropdown) is set to:

DataCardValue41.Selected.Value

This ensures the correct integer value from the choice is saved.

Thanks!

Regarding this image:

I solved this issue by changing the combo box from Classic to Input style.

I am really not certain if this was actually an issue or not (more on that in a minute), but frankly kind of like the input style better anyway.

After I made those changes and checked replies here, on your advice I checked and found a couple of things.

One of the data cards combo boxes had a couple of things gone missing.

First was the border color changed by errors, and the second and more important was the update property got blanked out somewhere along the line. Not sure when, but it was.

I say I am not sure if the style of combo box really matters because I just resolved the primary issue here and have not tested.

Thanks for your reply!
