How to compare a text field data with a recordType or readonly grid column data.


I have an interface where I am loading the data in a read only grid using a recordType and also I have a "ADD" button to provide a new item to add.

Now, when the user is trying to save a text fields data, I would like to compare text fields data with a recordType fields/columns..

Can someone advise on how to compare user enter data in a text field with a recordType or Read only grid column. If user is trying to enter same data, I would like to return a validation message.
