An example of an AI chatbot conversation about model binding and validation in ASP.NET MVC.
What is model binding in ASP.NET MVC?
Model binding in ASP.NET MVC is the process of converting data from HTTP requests into .NET objects, making it easier to work with user input.
How does validation work with model binding?
Validation in ASP.NET MVC occurs after model binding, where the framework checks the model's properties against data annotations to ensure they meet specified rules.
Can you give an example of a validation attribute?
Sure! The [Required] attribute ensures that a property must have a value. If it's missing, the model state will be invalid.
What happens if the model state is invalid?
If the model state is invalid, the controller can return the user to the form with error messages, allowing them to correct their input.
