Pls find the attached image.
I have 2 dropdowns (NewsSector, NewsSectorType). when i select values from these 2 dropdowns and click on Add button, it will add rows to grid. Here i need to do validation ie if user is trying to add the same row which is alreday existed then it has to show pop up message that "Please select another NewsSector and NewsSectorType as it is already existed".
can we do this validation in client side? If so, how?
