Explaining Two-Way and One-Way Data Binding in Blazor

Two-Way Data Binding:

In Blazor, two-way data binding allows changes in the UI to automatically update the underlying data model and vice versa. This means that when a user interacts with a control like an input field, the data in the model is updated instantly and vice versa.

Example of Two-Way Data Binding:

@bind-Value attribute in Blazor components enables two-way data binding. For instance, when creating a form where a user can input their name, using @bind-Value on the input field would keep the entered value in sync with a corresponding property in the data model.

One-Way Data Binding:

With one-way data binding in Blazor, changes in the UI do not automatically reflect back to the data model. This means that the UI presentation is determined by the current state of the model, but any modifications made in the UI are not propagated back to the model.

Example of When to Use One-Way Data Binding:

One-way data binding is suitable when you want to display static content or when you want to ensure that changes made only affect the UI without altering the original data model. For instance, displaying a list of items retrieved from a database where the data is not meant to be edited in the UI.
