This article will explain UpdateModel and TryUpdateModel in ASP.NET MVC. We will also discuss the differences between them. What is the different between UpdateModel and TryUpdateModel? The major difference is that UpdateModel throws an exception if validation fails whereas TryUpdateModel will never throw an exception.
As you can see from the screenshot, shown above, we are getting a validation error. UpdateModel () throws an exception, if validation fails, whereas TryUpdateModel () will never throw an exception. The similarity between both is that the functions are used to update the model with the form values and perform the validations.
Web. Mvc Controller. Try Update Model Method System. Web. Mvc Updates the specified model instance using values from the value provider, a prefix, and included properties. Updates the specified model instance using values from the controller's current value provider, a prefix, a list of properties to exclude, and a list of properties to include.
When using UpdateModel, if it has any issues while binding properties it will throw an exception, informing that there was a binding error.
Whereas TryUpdateModel does not throw an exception if there are any binding errors, instead it logs the error in the model state dictionary, which you can check using ModelState.IsValid property.
