In this article we will be seeing how to do custom validation for site column in SharePoint using power shell and SharePoint object model.
I have created a list "Resume" where the users can upload the resume and will be filling some basic details. I have four columns:
Years of experience
I am going to do some custom validation for "Years of experience" column. Only users who have experience of 3-6 years can upload the resume.
I have created a custom validation as shown in the following which has the Formula and User message (where you can display some custom error message).
Go to SharePoint site -> List -> List Settings -> Columns -> click on the column to edit.
