The ASP.NET Core TreeMap component displays tree-structured data as a set of nested rectangles. Each branch of the tree is given a rectangle, which is then tiled with smaller rectangles representing sub-branches. By construction, the TreeMaps make efficient use of space. As a result, they can legibly display thousands of items on the screen simultaneously.
The ASP.NET Core TreMap is one of the many Telerik UI for ASP.NET Core controls that are supported in both MVC and Razor Pages applications. To view the complete list of Telerik components that you can plug in ASP.NET Core Razor Pages projects, check out the documentation article or visit the Razor Pages examples in our GitHub project repository.
HTML and Tag Helpers
The Telerik UI for ASP.NET Core offers two ways for declaring UI components. You can choose to use HTML or Tag helper to implement the TreeMap, depending on your technology background and development preference and practice.
The TreeMap can be customized to satisfy your needs with the help of our 20+ built-in themes or by simply changing the colors of each item in the component to match the style of your project. You can easily customize any of the out-of-the-box themes with a few lines of CSS or create new themes by using the Telerik SASS ThemeBuilder application.
