Description

The Telerik UI for ASP.NET Core ComboBox supports a virtualization feature which is useful for large data sets. As shown in the demo, the ComboBox component renders a fixed number of items at once and when scrolled, takes the rest of the items and displays them within the same format. To enable virtualization, create Read and ValueMapper actions, and, then, set the desired number of items that will be rendered.

Additional Apps

This ComboBox example is part of unique collection of hundreds of ASP.NET Core demos, with which you can see all Telerik ASP.NET Core 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 ASP.NET Core or ThemeBuilder.
