The Exontrol's ExTree component delivers a powerful and highly customizable tree control, designed to meet the demands of modern user interfaces. Whether you're looking to implement a classic hierarchical tree, a multi-column tree, a list, or even a list-view style control, ExTree has you covered. This advanced component goes beyond standard tree functionality by offering extensive features such as built-in filtering, multiple selection, in-place editing, ADO/DAO support, ActiveX hosting, and conditional formatting. Its flexible structure allows you to embed images, radio buttons, checkboxes, HTML content, and even host other ActiveX controls directly inside tree items.

A major strength of the ExTree control is its skinnable interface. Using EBN (Exontrol Button) technology, ExTree lets developers apply skins to any visual element of the control, including scrollbars, headers, backgrounds, and cells - providing a unique, visually appealing user experience. Skins are easy to create and integrate, allowing full control over the component’s look and feel.

From professional list navigation to complex data representation, ExTree is a versatile and dependable solution for any application interface that requires structured, rich-content display.
