  • 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.
  • Single and Multiple Selection

    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.
