I know there are several other posts about the Modern ComboBox controls, and I understand that they are not yet finished...

But I can't figure out why it would work in the Studio, but not in Play mode...?

Items = col_VehiclesList

DefaultSelectedItems = Filter(col_VehiclesList,ID = int_SelectedVehicleID)

In Studio:

In Play Mode with EXACTLY the same record:

Anyone else having issues with the Modern ComboBox?

I just wanted to add a quick Update...

The above issue was discovered and recorded when using Google Chrome.
I had a brainwave overnight, and decided to see what happens in Edge.

Well, it turns out that Edge is even worse - the Modern ComboBox is not showing the DefaultSelectedItems in the Studio either!
Highlighting the formula shows that the value is calculated OK, but nothing is shown.

I have also experimented with Resetting the ComboBox, but this doesn't seem to do anything...

What is even more confusing is that I have another Modern ComboBox a little lower down the page, and this one works without any issues:

Go figure?

Im running into the same issue now. Did you figure out a solution, or is this just a PowerApps bug?

After running into this bug myself I found a workaround until Microsoft makes a fix.

When trying to troubleshoot where the issue was I made a gallery that displays the data in the dropdown, highlighting the defaultselecteditem. To my suprise, my combobox was working after doing this.

What I finally ended up doing was adding a label with visible=false and the text being a lookup of the value being displayed in the defaultselecteditem.

Thanks @Elke ,

I gave your suggestion a try, and I added a Label with the Text= ComboBox1.Selected.Title

Unfortunately, it does not show any value, and PowerApps Studio shows the formula to resolve to Blank...

Whereas when I hover over the Formula for ComboBox1.DefaultSelectedItems, the Studio evaluates to the correct record...

So I'm afraid that workaround doesn't work for me.

I guess we just have to wait for Microsoft to fix the BUG and take the control out of "preview"...

James.

I also have the problem that the property of DefaultSelectedItems does not show the correct result. I used it in a gallery. I wish the could be a communication to microsoft regarding this issue.

Sorry I didn't mean the DefaultSelectedItems property.
I meant the value which represents it.
For example my defaultselected items is based on a lookup, so I display the lookup in my label. Hope this helps!
