Updating a MVC 5 Bootstrap 3 web application with Kendo MVC v2023.1.117.545 to v2025.1.211.462

As the title states, I have a legacy monolith that must be revived.

I need a few features, especially on the grid, and decided to upgrade Telerik. After a bit of struggle, I managed to run the application but the Telerik controls are by default very small compared to before and the new Size property doesn't seem to be doing much:

Before:

Now:

As it can be seen, the grid shrunk. I do not have a lot of custom CSS on this site but the baseline theme was Start Bootstrap v2 (Start Bootstrap - SB Admin 2 Bootstrap Admin Theme (http://startbootstrap.com)). Not sure if the original theme can still be found.

Would you please confirm which Kendo UI theme you use?

If you use Bootstrap 3 swatch, make sure that the following theme version is referenced in the application:

<link rel="stylesheet" href="https://kendo.cdn.telerik.com/themes/10.2.0/bootstrap/bootstrap-3.css"/>

<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<script src="https://kendo.cdn.telerik.com/2025.1.211/js/kendo.all.min.js"></script>
<script src="https://kendo.cdn.telerik.com/2025.1.211/js/kendo.aspnetmvc.min.js"></script>

For example, here is a REPL sample that contains a Grid and the Bootstrap 3 swatch:

I'm using the theme installed: <path>\Progress\Telerik UI for ASP.NET MVC 2025 Q1\styles\bootstrap-3.css

HI,

I am sending you a runnable ASP.NET MVC application that uses the latest Telerik UI for ASP.NET MVC version with the Bootstrap 3 swatch. Please review it and let me know if the Grid is sized based on your expectations.

Best,
Mihaela
