The Wisej.Web.TreeView control shows nested items within a hierarchical tree. Each item can have a number of subitems, allowing the user to expand and collapse nested items accordingly.
For a full list of properties, methods and events see the API documentation.
The TreeView control features a CheckBoxes property that will display a checkbox next to each node in the TreeView.
The TreeView control has the ability to use virtual scrolling, a feature that only renders the list items currently visible in the browser.
Using this option can drastically reduce the amount of time spent rendering in the browser for large datasets.
Scrolling when VirtualMode is true may be slower than rendering all of the items at the same time. To improve scrolling performance, set the PrefetchItems property to pre-render items.
