No error message when attempting to save a duplicate item
I have a SP list with a column that requires unique values. When I submit the form (customized in PowerApps) with a duplicate value in that column, it doesn't let me save it, but it doesn't produce an error message. It just does nothing. What's missing?
As a workaround, you can add a warning label by yourself following below steps. Notice that whenever you cannot submit the item, the message would appear. So I have added other possbile reason, like a required field is emply.
1. Set the OnFailure property of the editform to:
2. Insert a Label control and set its Visible property to:
Set its Text property to:
"xxx field must have an unique value or xxx required fields are empty."
