Items property of a ComboBox

I have a Data Verse table A with a lookup column 'Project' to Table Projects ( Table B ).

I have a ComboBox which has the Items property as Table A. In the ComboBox, I want to show the column 'Project'.'Project Name'.

In the ComboBox DisplayFields property, I have ["TableA_Name"]. I have tried to change it to ["TableA_Project"], but it changes back to ["TableA_Name"].

Can anyone show me how to get the names of all the Projects in Table A in the ComboBox?

Thank you

I rarely - if ever - use Dataverse but I think your Items should be something like

Choices([@'TableA'].Project) // Note: use intellisense after the dot(.) to make your selection

I stepped through the Project app build setout by Reza Dorrani in this video and it may have some insights that you can use?

Failing that, you may find help for your question in this forum. I tend to find there's better help for Model-Driven Apps / DataVerse questions over there

Hi @qxaziz123 ,

Please try the following on the items property of the combobox:

ForAll(Table A,Project.'Project Name')

Please note that although this function is not delegable, you should not show a lot of items on your combobox anyway. Because, it is a bad practice from user experience point of view to show a lot of items in comboboxes. So, if your parent table has large data set, you may need to filter the result either through a predefined or user-defined criteria.
