The following quick start guide is intended to get you up and running with the MaskedTextBox control. In this quick start, you add a MaskedTextBox control to your application and add various masks to it. In the following example, we created a personal details form for an employee with seven MaskedTextBoxes having different input masks for each field (Name, Social Security Number, Address, Zip Code, Zip+4 Code, Phone Number, and Text Code).

The following Images show how the masked text boxes appear at runtime and after the information is filled in them.

Create a Blazor App

In Visual Studio, select Create a new project from the Get started pane.
In the Create a new project dialog, select Blazor App and click Next.
In the Configure your new project dialog, provide name of the project you want to create in the Project name field and location for the project in the Location field. Click Create.
In the Create a new Blazor app dialog, select Blazor WebAssembly App template and click Create. A new client-side Blazor app is created. Alternatively, you can also create a Blazor server-side app.
Note: Blazor Server App or server-side app can be created using the Blazor Server App template. For more details, see Blazor サーバー topic under Blazor Project Types.
