TreeList

Keyboard Navigation

The name gives it away, but we have officially added full keyboard navigation support to the TreeList component.
Batch In-Cell Editing

As the name gives away in-cell (or “batch” as it is called as well) allows end-users to edit individual cells rather than putting an entire row in edit mode. Updates, additions, or items that have been removed, can then be synced in one single request going back to the server.
Client-Side Paging

This feature is intended to help with large data sets within the TreeList. It is currently specifically for the client-side, which means that all of the data has been loaded on the client, but this new feature should help tremendously in the way of performance.
MultiColumn Headers

Often times we may want to showcase that the headers of a grid are part of a particular category or group, which is where multi-column headers come in to play! This gives you the option to define a column which might span over several sub-columns.
Effortless Presentation of Hierarchical Data

Telerik ASP.NET Core TreeList helps you display self-referencing data in a user-friendly manner by combining the features of a Grid and a TreeView.
Sorting and Filtering

Using just a few property settings you can enable users to sort and filter data through a slick and intuitive interface.
Insert, Update and Delete

Provide the ability for users to insert new, edit existing or delete data from your data source. You can enable editing inline or via a popup form.
Aggregates

Telerik TreeList extension for ASP.NET Core enables you to display aggregates in the column footer cells, such as sum, count, average, etc.
Excel and PDF Export

Export the full content of the list-view control into PDF and Excel. Customize the exported file to include exactly the content that is needed.
Data Binding

Use the DataSource component to bind the TreeList control to static arrays, dynamic objects, local or remote data, or even SignalR hubs. The built-in Ajax binding is especially useful in ASP.NET Core scenarios.
Built-In, Yet Customizable Themes

Create a consistent look for your apps and save design and front-end development time by applying any of the ready-to-use themes. You can easily customize the existing themes or create your own with the ThemeBuilder tool. With the point-and-click configuration wizard, your new themes are ready in a matter of seconds.
Mobile Support

Why do you need to build a mobile version of your app when the same application can work equally well on mobile and desktop devices? You can rest assured that your ASP.NET Core TreeList will work across all screens and will handle touch events as if triggered by a keyboard or a mouse.
Accessibility

The Telerik TreeList is perfect for scenarios where accessibility is important for your application. The control complies with Section 508 and WCAG guidelines, ensuring that individuals with disabilities can still view and interact with it.
Cross-Browser Support

Using the ASP.NET Core TreeList, you can be certain that your app will look and behave as expected across all browsers.
