You can use the OnItemRender event of the TreeView to apply conditional styling on its nodes based on a certain criteria. The OnItemRender event fires when each node is about to render. It allows you to set a Class for the div element based on your business logic.
This TreeView Item Formatting example is part of a unique collection of hundreds of Blazor demos, with which you can see all Telerik UI for Blazor components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for Blazor or ThemeBuilder.
