Tips for reducing the size of the ValidationMessage string in Blazor

Exploring the world of Blazor for my new project, I find myself faced with a challenge. My page is filled with text input fields that need to be validated upon submission.

How can I ensure these messages break into multiple lines for better display? Code Code

Answer №1

To customize the appearance of the default ValidationMessage component, you have a few options:

  • Create a custom C# class for ValidationMessage, and apply your own CSS class. Alternatively, you can use Bootstrap or other CSS frameworks for styling (see example in this Stack Overflow answer)
  • A quick but less elegant solution is to modify the existing validation-message class in your app.css or site.css file(s) to adjust how it displays lengthy error messages
  • You can also create a custom validator component for Blazor by following a guide like the one provided in this article
