Combo Box get wrong data source?

[carem]

I create a Combo Box in a blank app, choose a List of Sharepoint to be Data Source. The list name "Assets"

And here is my setting of the combo box Control to pull out the value of "Origin" of the "Assets"

You can see when I choose the value of my Combo Box. All the names of fields no belong to the Assets List.

What did I miss or What was I doing something wrong?

Have you tried Refreshing the datasource (on the left-side menu) to see if the columns appear?  If that does not work, try to delete and then re-add the combobox.  Let me know the result.

Hi @carem ,

Could you please share a bit more about your scenario?

Do you mean that the available fields listed under the "Primary text" property does not belong to Assets SP List?

Could you please share a bit more about the data type of the "Origin" field? Is it a Text type field or a Choice type field?

Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned.

1. If the "Origin" field is a Text type field in your Assets SP List, please consider set the Items property of the ComboBox to following:

Distinct(Assets, Origin)

2. If the "Origin" field is a Choice type field in your Assets SP List, please consider set the Items property of the ComboBox to following:

Choices(Assets.Origin)

Please consider take a try with above solution, check if the issue is solved.

If the issue still exists, please consider remove the Assets SP List data source from your app, then re-add it again in your app, try above solution, check if the issue is solved.

Best regards,
