How-To: Create New Blazor Component

Blazor apps are based on components. A component in Blazor is the atomic unit of composition for any UI element, such as a page, control, dialog, or data entry form. Components are .NET C# classes built into assemblies. They can: Define UI rendering logic.Handle user events.Be nested and reused.Be shared and distributed as Razor class libraries or NuGet packages. The … Continue reading How-To: Create New Blazor Component

Lesson 6.3: Create Blob Storage Repository

In Chapter 5, we created a repository interface (IReadableRepository) and repository implementation (InMemoryReadRepository) that loaded data from embedded resource files. We designed our system with these abstractions because we want to try out several Azure storage technologies, and the repository interface gives our service code a measure of isolation from the data implementation technologies. As … Continue reading Lesson 6.3: Create Blob Storage Repository

How-To: Create Blazor App Splash Screen

When applications require time to load up, they usually provide a splash screen to give the user something to watch, provide feedback that the application is loading, and start building the user interface branding for the app. Blazor also has the ability to show an HTML splash screen, while the Blazor WebAssembly and possibly the … Continue reading How-To: Create Blazor App Splash Screen

How-To: Unit Test Blazor Pages with DataBinding

Continuing with our use of the bUnit testing library for Blazor components. We will investigate how to create unit and component tests for pages/components that use both one-way and two-way data bindings. We will look at changing data on the page and performing actions (like button clicks) and then seeing how that impacts the page rendering. … Continue reading How-To: Unit Test Blazor Pages with DataBinding

App-Idea 3: Ultra Number Converter

Inspired by the number converters in the app-ideas project, I decided to create an uber number converter that allows users to pick from various number systems and convert to another one... instead of build more converters for octal and hexadecimal. Plus, this allows us to learn about build more complex UI in Blazor. In this … Continue reading App-Idea 3: Ultra Number Converter

How-To: Add Two-Way Binding to Blazor Page

In order to support taking user input in components and pages, Blazor supports a form of two-way binding which updates either when the user makes a change in the element or when the system updates the backing property/variable. When the variable changes, this two-way binding works exactly like one-way binding - the component is rendered … Continue reading How-To: Add Two-Way Binding to Blazor Page

How-To: Add Blazor Component Interactivity with One-Way Binding

Building a static HTML page with Blazor is pretty easy, but doesn't make for an interesting application. To support basic interactivity, Blazor components/pages use databinding to show dynamic data and respond to events on the component and its elements. The simplest form of databinding is one-way binding. One-way binding renders the data from our code … Continue reading How-To: Add Blazor Component Interactivity with One-Way Binding

App-Idea 2: Roman to Decimal

Another number conversion project (Roman-To-Decimal) takes numbers represented as roman numerals from input strings and converts them to their decimal value. Again, we will add the ability to convert back from decimals to roman numeral notation as well. This conversion project will use the same layout design as the Bin2Dec project. We will add this … Continue reading App-Idea 2: Roman to Decimal
