ModelState. IsValid tells you if any model errors have been added to ModelState . The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.

Thereof, what does ModelState IsValid mean?

ModelState. IsValid indicates if it was possible to bind the incoming values from the request to the model correctly and whether any explicitly specified validation rules were broken during the model binding process. In your example the, the model that is being bound is of class type Encaissement .

Similarly, what is ModelState? ModelState is a property of controller that is used for validating form in server side. You must add System. Web. Mvc namespace in order to use it. ModelState is a collection of name and value pair that was submitted to the server during post.

Additionally, why ModelState IsValid is false in MVC?

If any errors are found, they are added to the Errors collection in the property's ModelState. Also note that IsValid is false now. That's because an error exists; IsValid is false if any of the properties submitted have any error messages attached to them.

What does ModelState clear do?

ModelState. Clear() is used to clear errors but it is also used to force the MVC engine to rebuild the model to be passed to your View. So call ModelState. Clear() right before you pass the model to your View.
