Features
  • Powerful Auto-complete Functionality
    r.a.d.combobox has full autocomplete support - while you type into the input area, the combobox fires a server-side event that returns all the relative matches for the currently typed text.
  • Load On Demand
    r.a.d.combobox can load data on demand based on the current value of the combobox input field. Whenever the state of the input changes, r.a.d.combobox fires a server-side event with the current state of the input as a parameter.
  • Template Support
    You can embed any content inside a r.a.d.combobox template, including HTML markup and ASP.NET server controls, as well as other third-party controls (and any control from the telerik r.a.d.controls suite as well).
  • Section 508 Compliance
    In compliance with Section 508 regulations, r.a.d.combobox is fully navigable using the keyboard. r.a.d.combobox can be accessed with the Tab Key as well as with an Access Key shortcut. You can use arrow keys to open and close the combobox and navigate through the items. Items can be selected with Space or Enter keys.
    r.a.d.combobox displays item tooltips which enables special accessibility readers like JAWS to pronounce the tooltip of the highlighted item.
  • Flexible Binding Mechanism

    • DataBinding: r.a.d.combobox fully supports binding to collections, tables and datasets.
    • Programmatic Binding: r.a.d.combobox provides a rich and easy-to-use server-side API, so you can easily populate your combobox with any number and type of items.
    • SQL Binding: You can easily bind r.a.d.combobox to the result of any SQL query.
    • XML String Binding: r.a.d.combobox provides rich API for working with XML. You can load data from an XML static content file or you can directly load XML.

  • Full Visual Studio Design-Time Support
    You can easily Add, Edit and Remove items in the Design Mode of VS.NET. r.a.d.combobox items are also very easily customized by Template Editing in Visual Studio.
  • Rich Set of Server and Client Events
    r.a.d.combobox provides an extensive set of Server- and Client-Side events which allow for easy use and customization of the control.
  • Support for Custom Attributes
    r.a.d.combobox provides full support for custom attributes both on the server and on the client. It is very easy to include an image in your combobox item, for example.
  • Appearance Customization
    r.a.d.combobox contains a predefined set of CSS-based skins which allow for easy appearance customization. You can also create custom skins of your own.
  • Integration in ASP.NET controls
    You can easily embed r.a.d.combobox inside any ASP.NET control supporting templates.
    Display over Windowed Objects
    r.a.d.combobox's dropdown can be displayed over windowed objects (ASP.NET dropdown lists and/or flash movies). In addition, r.a.d.combobox is not rendered as a windowed object, therefore DHTML content can hover the combobox when needed.
  • Validation
    You can use the built in ASP.NET validation with r.a.d.combobox.
  • Multi Language Support
    You can use any language with r.a.d.combobox. Just make sure you've set the appropriate Html encoding (and XML encoding in case you are using XML Content Files).
  • Support for Right-to-Left Languages
    r.a.d.combobox provides full support for Right-to-Left languages.
  • Sorting
    r.a.d.combobox supports automatic sorting (Ascending, Descending) based on the Text property of the control.
  • Multiple ComboBoxes
    You can easily setup any number of instances of r.a.d.combobox on the same page that interact with each other based on certain client-side or server-side events.
