I have a requirement like this.
I have a SharePoint list called & # 39; Examdate & # 39; which stores different CoursNumber, Semester and ExamDate. Use an InfoPath form to enter the CoursNumber in the list.
Now they need to have a mechanism to find out if the user is adding a New Examination Date whose CoursNumber is already present. They do not want users to stop the addition process, but they want to show the ExamDate for this existing CoursNumber in the form. This should not happen on the Save button.
So, I was thinking of customizing the
New article form by adding a button near the CoursNumber field, say "Verify existence", and verify if the CoursNumber and the semester exist for that number entered by the user. But I do not know how I can implement this.
What is the best and simplest way to do it?
