Models:-

• Want validation summary only for Item Name, Quantity, unit Price and product Group dropdown

• Is it possible to get validation summary of specific models?

Answer 1

As per you view your viewmodel should only contain properties that are present in view. ex.ItemName,Product group image, sequence no. etc.
Create another viewmodel that contain only these properties and use it in your view.

However some of the properties that you've used like int32 etc. are always going to be validated by default. if you want to change that behavior make nullable properties for them.
