Overview of the EditForm component
In the previous chapters of this book, we used the standard HTML form element to collect user input. However, the Blazor WebAssembly framework provides an enhanced version of the standard HTML form element called the EditForm component.
The EditForm component not only manages forms, it also coordinates both validation and submission events. The following code shows an empty EditForm element:
<EditForm Model="expense" OnValidSubmit="HandleValidSubmit"> </EditForm>
In the preceding code, the Model property specifies the top-level model object for the form. The OnValidSubmit property specifies the callback that will be invoked when the form is submitted without any validation errors.
There are three different callbacks that are associated with form submission:
OnValidSubmitOnInvalidSubmitOnSubmit
We can use the OnValidSubmit and OnInvalidSubmit callbacks together...
