RadComboBox for ASP.NET AJAX implements a highly efficient semantic rendering, which uses list items and CSS instead of tables. As a result the HTML output is significantly reduced, which dramatically improves performance.
RadComboBox for ASP.NET AJAX supports binding to all ASP.NET 2.0 declarative datasources (AccessDataSource, ObjectDataSource, SqlDataSource, SiteMapDataSource, XmlDataSource) as well as the new LinqDataSource. The control can also be bound to web services on the client and load data on demand which results in previously unattainable performance boosts.
RadComboBox for ASP.NET AJAX has a rich client-side API and comprehensive set of events guaranteeing full control over various functions performed on the client. You can easily add/delete/update items at the client side and all the changes will be persisted on the server as well. The rich client-side API provides unbeatable performance and desktop-like experience.
To improve the response time perceived by end users RadComboBox for ASP.NET AJAX loads data on demand based on the current value of the combobox input field.
RadComboBox for ASP.NET AJAX has full autocomplete support - while you type into the input area, the combobox returns all the relative matches for the currently typed text. Autocomplete for multiple items using any delimiter (";" , ",", etc.) is also supported - just like in Microsoft Outlook®.
RadComboBox for ASP.NET AJAX is compliant with the XHTML 1.1 requirement. The control satisfies the requirements of "Section 508" for software accessibility, as well as those of "Level AAA" (in accordance with the W3C Web Accessibility Guidelines 1.0). RadComboBox also has full support for keyboard navigation with Shortcuts, Access Keys and Arrow-key navigation.
RadComboBox completely follows the principles of Search Engine Optimization. The control's innovative rendering generates semantic lists and standard <a> tags, which are properly recognized and highly valued by search engines. As a result, all content accessible through this control will be automatically indexed and ranked with no extra effort required from the developer.
RadComboBox provides rich design time support functionality making customizations and configurations very easy. Some of the key capabilities are:
• Applying skins in design time and easily switching between them - the Choose Skin command in RadComboBox Smart tag automatically detects the preset skins
• Item Builder dialog for easy inline creation
• Design-time support for declarative data sources
RadComboBox supports a variety of expand animation styles for a great user experience. You can select among predefined animations and further customize them with any settings relevant for your scenario.
Multi-column mode supports all advanced AJAX features of the combo – load on demand, auto-complete, etc. Items loaded on demand are automatically formatted using the templates as well. RadComboBox also supports static column headers: through headers you can assign column titles for each combo column. The header does not scroll when items go up/down and is always visible – end-users can easily associate column data to its respective column title in the header.
RadComboBox is shipped with a rich set of skins that allow you to easily build slick interfaces with the look-and-feel of Windows Vista, Office 2007, Outlook, etc. The skins can be easily switched using a single property.
RadComboBox provides full support for custom attributes both on the server and on the client. It is easy to customize the item and include any attribute relevant for your scenario: additional text, value or image.
You can embed any content inside a RadComboBox template, including HTML markup and ASP.NET server controls, as well as other third-party controls (and any control from the Telerik RadControls suite as well).
RadComboBox provides full support for Right-to-Left languages.
