Description

The Telerik Blazor ComboBox provides support for UI virtualization to significantly improve the performance for large data sets. To enable it, set the ScrollMode, PopupHeight, ItemHeight and PageSize.

You can also use filtering with virtualization, and you can fetch the data on demand through a remote service, so you don't have to load all the available records at once, you can only request those the user scrolls or filters to.

The component also provides a NoDataTemplate. Use it to customize the dropdown content when there are no items to display.

This ComboBox Virtualization 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.
