The Blazor ListBox control is a graphical user interface for displaying a list of items with multi-selection options. It has a rich appearance and allows users to select one or more items from the list using checkboxes or keyboard interactions. It has several out-of-the-box features, such as data binding, sorting, grouping, reordering, dragging and dropping, UI customization, and accessibility.

Data binding

You can bind data from a variety of data sources such as JSON data collections or remote data sources using different kinds of adaptors such as OData, OData V4, URL, JSON, and Web API. The control uses JavaScript data manager to manage data and also has customization options for data requests and processing.

Checkbox selection

No, our 1,800+ components and frameworks for web, mobile, and desktop, including our Blazor ListBox, are not sold individually. They are only available as part of a team license.

We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 1,800+ components and frameworks for a subscription fee that starts at $395 per month for a team of 5 developers. Additionally, we might be able to offer discounts based on currently active promotions. Please contact our product specialists today to see if you qualify for any additional discounts.
