❔ Access 2 properties from validationRule
Hi everyone,
I have a valdiation rule on textbox ID when entering a new user. A user inputs ID which is a unique string every person has. I have a validation rule that checks the ID against the db column ID to see if it is unique and hasn't been inputted before. This all works. The issue is that you can also edit an existing user. The user that is edited will throw the validation error for ID because the validation rules still checks the ID against the DB. I wish to access the newRow property from the VM in the validationRule so that the rule would only throw an error if the newRow flag is true. How can I do this?

(why would someone enter an id? it's managed by the db, if it's given by the user he could make mistakes)
Its not an actual ID its a think like a social security nr for in my country just simpler to write ID
ok, so you are saying the "validation rule" is in your code instead than in the table?
Yes it is in my C# code why would it be in my table?
for example given that that is a standard feature of every db you wouldn't have this problem
