Date Loan Start
Due Date
Solved! Go to Solution.
Hi @Faisal_Baloch ,
ComboBoxes have this quirk where the DisplayFields and SearchFields properties reset after you make changes to the Items property. In this case they have probably reset to display the Role column which is actually blank:
When changing the selected column in the DisplayFields property to Full Name, the proper values are displayed:
For the BookCopy combobox the column to select is Book Copy Reference.

No worries I have added the field fresh and the data is appearing. But a very doggy performance by the application...
Hi @Faisal_Baloch ,
The column to select is Full Name, not First Name since that is not populated either in the data source:
Removing and adding back the field may indeed also fix the issues, but making sure the right column(s) are displayed is faster/better.
I have done as solution indicates and fields show full name as well as Book Copy Reference, yet I still do not have the drop down list of books or students. Any other ideas are appreciated.
nevermind, saw the remove and re-add. to quote op, pretty dodgie.
Good day,
I'm having difficulties when trying to do a check out as the student and book names are not populating, I followed some instructions on how to resolve this issue with no luck.
Please assist
Hi @montshiwaek ,
The red texts you see is because you are trying to submit the form without selecting values for those two fields. Can you please confirm you are (not) able to see the values in the combobox controls when expanding the options (clicking the chevron icon on the combobox) whilst previewing the app?
Hi @BCBuizer
Yes, I'm unable to see the values in the combobox controls when expanding the options. I also tried to delete the App and redo it but still get same results. However I'm able to search for the student and click checkout as attached but when I try and select the student name no values are shown.
