Can help? When in debugging mode of the database page (Database.aspx), I try to update the details by modifying the fields in the EditItem template. But then, when I click "Update", the data cannot be updated and shows the error message: "Data could not
be updated. Please try again."
This is the most common issue in my project.
Is there a way to fix this problem?
