How to Change All Your Textbox Input Letters to Uppercase in MVC Razor Page

In web development, ensuring consistency in user inputs is vital for maintaining a clean and professional appearance. One common requirement is to change all textbox input letters to uppercase across a web application. If you're using ASP.NET MVC with Razor pages, you're in luck! This guide will guide you through how to implement this functionality easily.

Why Change Input to Uppercase?

There are several reasons you might want to convert input letters to uppercase:

Data Consistency: Ensures that all data entries are uniform, making it easier to read and process.

User Experience: It can minimize input errors, especially for fields like names, where capitalization is often expected.

Styling: Uppercase letters can also enhance the visual appearance of your application.

Step-by-Step Solution

1. Using jQuery for Automatic Conversion on Page Load

To automatically change the text input letters to uppercase as soon as the page loads, you can utilize jQuery. Place the following script in your view:

Whether you're focusing on improving data consistency or enhancing the appearance of your form fields, these techniques will serve you well.
