Custom Data Annotation Attribute using Metadata

My requirement is to create a custom data annotation attribute for my project. The requirement is to validate the min/ max length of a specific product from the database, which will be retrieved from the database using the ProductID. I have a dynamic page for each product where there are two fields called max length & min length. User inputs the values in these two fields which needs to be validated from the database. Product table contains all the products & one will be selected by passing a productId.

Please suggest some pointers to implement the above.

Thanks in advance.

This validation you can do only in the server side and not in client, so I see two options.

  1. Remote Validation - You can use remote validation when you want to perform the validation and show the error message through ajax.

  2. IValidatableObject - By implementing this interface in the class you can do both the validations at the same time and return all the validation error messages as a collection. By this way the validation will happen after the form is normally submitted.
