How to Make Your InputNumber Component Read-Only in Blazor

Blazor has made it increasingly simple for developers to create dynamic web applications using C# . As part of its built-in forms components, InputNumber is a favorite for handling numerical input. However, you might encounter situations where you need to display a number without allowing users to modify it — in other words, a read-only state. Let's take a closer look at how you can achieve this with ease.

The Challenge

When developing forms in Blazor, you might find that certain fields must be presented as read-only, especially in scenarios like reviewing information or displaying data fetched from a database. Ensuring that users cannot change certain inputs helps in preventing errors or accidental modifications. But how do you implement this functionality for the InputNumber component?

The Solution

The solution is surprisingly simple! You can make the InputNumber component read-only by using the readonly attribute directly in your markup. Here's how you can do it step by step:

Step-by-Step Guide to Making InputNumber Read-Only

Define the Component: Start with the basic syntax to include the InputNumber component in your Blazor form.

Add the Read-Only Attribute: Include the readonly attribute in your component definition. This will ensure that the user cannot change the value.

Example Code

Here is an example of how you can implement a read-only InputNumber in your Blazor application:

Explanation of the Code

InputNumber: This is the Blazor component responsible for handling number input.

readonly: This attribute makes the input field non-editable by users.

Id="name": This provides a unique identifier for the input element, which is useful for accessibility and styling.

Class="form-control": This ensures that the input field receives proper styling.

@ bind-Value: This directive binds the input's value to the specified model property. It enables two-way data binding in Blazor.

Conclusion

Making an InputNumber component read-only in Blazor is a breeze with just a minor adjustment to the attribute list. By following the straightforward steps provided above, you can seamlessly enhance user experience by preventing unwanted edits in your forms. Remember, user interface consistency and clarity are key when designing forms, and utilizing the read-only state effectively can lead to a more intuitive application.
