Data Binding: Server-Side and Client-Side
You can bind Telerik ASP.NET DropDownTree on the server to any ASP.NET data source control (AccessDataSource, SqlDataSource, LinqDataSource, EntityDataSource, ObjectDataSource, XmlDataSource, OpenAccessDataSource) or on the client to Web Services.
Users can select a single item or multiple items via checkboxes. You have full control over what users can select – an individual node, the node and its children or Tristate.
Allow your users to quickly find items by typing. RadDropDownTree comes with two built-in filters: "Contains" and "StartsWith." For optimal performance, the control allows you to set the number of minimum characters typed by the user for the results to start appearing.
Add images, change the fonts, colors and backgrounds of the RadDropDownTree header, footer and nodes through server or client templates to best match the control’s appearance to your scenario.
Rich Set of Server-Side and Client-Side Events
Leverage the full set of server-side and client-side events of Telerik DropDownTree to handle every user interaction and create custom interactivity for your project.
Keyboard Navigation Support
RadDropDownTree allows your users to use the keyboard for any action they can trigger with the mouse, including opening and closing the dropdown, navigating, expanding and collapsing the items and more.

Drag and drop it onto the design surface and use the SmartTag, the Properties Window or the rich Design-Time wizards to codelessly configure the control and make it fully functional.
