Understand Cascading Parameters and Cascading Values in Blazor |
|
In the previous article we discussed arbitrary parameters and attribute splatting. Now it's time to understand one more aspect of passing values to a Blazor component from the external world - Cascading Parameters and Cascading Values. In all the examples discussed so far, we explicitly set a parameter value from the parent component. This means if we want to pass a value to, say, ten components, we must set a parameter of all the ten components. In such cases Cascading Parameters and Cascading Values come handy. The remainder of this article discusses how. |

Use Arbitrary Parameters and Attribute Splatting in Blazor |
|
In the previous article we discussed how parameters can be passed to Blazor component. In the examples discussed so far you created a fixed number of parameters (for example, Value parameter of the Message component) and assigned them some value from the parent component (Index.razor in our examples). What if you want to pass arbitrary number of parameters to a component? That means you won't the exact parameters at development time. The parent component (Index.razor) will set arbitrary parameters on a child component (Message.razor) when the child component is used. This article explores how this can be accomplished. |

Separate UI and Code in Blazor |
|
Blazor apps consist of one or more components. Components reside in .razor files and consist of UI markup and C# code. When you create a new Blazor server or WebAssembly project it stores component UI and code in a single file. However, at times this single file approach might not be adequate. Luckily, you can separate your UI markup and C# code easily. This article shows how. |

Integrate ASP.NET Core Identity with Microsoft account |
|
In the previous article you learned to use Microsoft Account as an external login to your ASP.NET Core web apps. In that article you didn't use ASP.NET Core Identity in any way. The Microsoft Account alone was used in the authentication process without any local account. At times you may want to integrate the Microsoft account with a local account. |

Authenticate users using Microsoft account in ASP.NET Core |
|
At times you want to integrate external logins with your ASP.NET Core applications. External logins include Microsoft accounts, Google, Facebook, or Twitter. When you use external logins, the login details such as user name and password aren't stored in your local database. They are stored in some external store and you are required to "get in touch" with that external source to authenticate your website users. In this article you will learn to integrate Microsoft Account based login mechanism in your ASP.NET Core web app. |
