Building a Blazor Form with the Command Pattern and Undo

Building a Blazor Form with the Command Pattern and Undo In a typical Blazor form, inputs update the model directly. That is simple and works fine for basic CRUD screens, but it starts to feel limiting when you want more control over how changes happen, especially if you want undo support. That is where the Command Pattern becomes useful. Instead of letting the form change the model directly, each meaningful edit is wrapped inside a command object. That command is responsible for two things: applying the change and reversing it later if the user clicks Undo. In other words, the form is no longer just changing values. It is recording actions. The basic idea In this approach, every field change becomes its own small object. So if the user changes FirstName, that is one command. If they change Email, that is another command. If they toggle IsActive, that is a third command. Those commands are stored in a stack, and Undo simply reverses the most recent one. The core interface is very small
