WebDropDown™ is a control that allows the end-user to select single or multiple items from a drop-down list. WebDropDown is built on top of the Ultimate UI for ASP.NET AJAX Framework to leverage a proven code base that promotes a high performance and responsive end-user experience. You can find the WebDropDown in the Infragistics.Web.UI.ListControls namespace.
In general, the WebDropDown consists of two main entities – Value Display for user input and a drop-down container that holds the items. WebDropDown includes integrated design-time tools in the form of an advanced Designer UI. This design-time utility helps you to quickly and easily set up the control depending on your requirements, providing access to a wide range of functionality without requiring intensive coding.
Like all Ultimate UI for ASP.NET AJAX controls, WebDropDown seamlessly integrates into the Infragistics® Application Styling Framework. With CSS based properties, you can manually customize the WebDropDown by leveraging your existing stylesheets.
WebDropDown also exposes a robust object model within the client-side JavaScript programming environment. The client-side object model (CSOM) consists of full-fledged properties and methods that enable developers to program significant units of functionality without the need for server-side postbacks.
Some of the the WebDropDown control’s features include:
High-Performance — Lightweight markup and optimized code improve performance.
Powerful Data Binding — Allows the developer to connect it to a data source and auto-generate the drop-down list.
Auto complete — Increases the user experience by suggesting the items in the drop-down list that begin with the prefix typed in the Value Display.
Multi-mode support — Different modes on how to display the WebDropDown.
Selection of Items — Single and multiple selection of items from the drop-down container.
Load-on-demand — Enables the WebDropDown to handle very large amounts of data without incurring any loss in performance.
Templates — Allows the developer to define an item template that can be used to customize the appearance of value items.
