I have to validate a editable grid for the following scenario -
I have two fields in the grid 1. Role 2. Location
use case - if the user select combination of same role and location as a duplicate then it should thrown an validation error like combination of role and location already exits.
example - if the user select role as developer and location as india and again he adding a new row and selecting the same role and same location it should throw an error
any one suggest some idea
