In this tutorial, we will learn how to implement custom attribute for validation in .NET Core. Default validation attributes like Range, MaxLength, and Required are available but sometimes custom validation is needed. We will create a new MVC application in Visual Studio and add a new class called UserProfile with properties like name and image. We will add custom attributes for image file to only allow specific extensions like JPEG or PNG.

To validate the form using HTML, we will use the HTML required attribute. The required attribute is a Boolean attribute that is used to specify the input element that must be filled out before submitting the Form. Data validation ensures accurate and useful user input.
Create a field validation rule Select the field that you want to validate. On the Table Fields tab, in the Field Validation group, click Validation, and then click Field Validation Rule. Use the Expression Builder to create the rule.
Server-side input validation will take whatever is sent by the client and conduct additional checks. Using server-side validation indicates that any input sent by the user (or client) cannot be trusted.
Server-side validation allows you to perform a server-side / API call and validate user input on the server after it has been submitted by the user. This approach has the following advantages: Increased Security. Since server-side validation occurs on the server, it is less vulnerable to tampering.
Apply data validation to cells Select Data Data Validation. On the Settings tab, under Allow, select an option: Under Data, select a condition. Set the other required values based on what you chose for Allow and Data. Select the Input Message tab and customize a message users will see when entering data.
There are two different types of input validation approaches: whitelist validation (sometimes referred to as inclusion or positive validation) and blacklist validation (sometimes known as exclusion or negative validation).
Input validation is performed to ensure only properly formed data is entering the workflow in an information system, preventing malformed data from persisting in the database and triggering malfunction of various downstream components.
A typical example is a user registration form. While a username may follow the client-side criteria for a valid username, newcomers wont know whether their registration will be successful until the server performs checks determining the uniqueness of the username against all existing users.
