Telerik Windows Forms DropDownList and ListControl come with a flexible data binding mechanism including support for binding to any object that implements IList, IListSource or IBindingList. This includes generic lists, arrays, and BindingSource. By using virtualization, the controls can be bound to thousands of items in milliseconds, re-enforcing Telerik's commitment to excellent performance without sacrificing features.
Telerik DropDownList comes with full autocomplete support, but it is up to you to decide whether users can enter free-form data or just select from the entries in the drop-down list. A single property setting switches editing on or off, making the text box section of the control editable or read-only.
When in editing mode the DropDownList selects or prefills the matching entry from the list as soon as the user starts typing. The different autocomplete modes are Suggest, Append, SuggestAppend, and Off. If you are using multi-line item text, the DropDownList uses the title label only, making programming and operation easier.
Double-click on the text box in a Telerik DropDownList and it will pull up the next item from the list. This timesaving feature allows your users to quickly advance through a list without the need to see all items.
Telerik Windows Forms DropDownList and ListControl support automatic sorting, based on the Sorted property of the control - simply set it to Ascending or Descending to sort in the respective order, or deactivate it to restore the initial ordering of the ItemCollection. Sorting may be case-sensitive or case-insensitive. Capital letters are displayed first in the former case.
Telerik DropDownList and ListControl allow you to filter data by applying a pre-defined filter pattern. The user can filter the combobox items in order to easily find what he/she is searching for. The controls can be configured to filter the items that start with the specified text, or the items that contain the specified text.
RadDropDownList and RadListControl by Telerik deliver convenience through integrated keyboard support. Once the control gets into focus, you can use the arrow keys to navigate through the items.
The controls are shipped with a rich set of pixel-perfect themes that allow you to easily build slick interfaces with the look-and-feel of Windows 8, Office 2010, Office 2013, Metro, etc. The themes can be easily switched using a single property. You can tweak existing themes or build a new theme from scratch to fit your exact visual demands by using the Visual Style Builder productivity tool. A well-thought light element tree allows for easy and intuitive styling.
The DropDownList and ListControl are also capable of displaying images, text, multiline text, and rich text by using standard HTML tags, such as <i>, <b>, and <u>.
Telerik DropDownList and ListControl provide full support for Right-to-Left languages, as well as localization support. See Localization and Right-to-Left Support for the full list of Telerik Windows Forms controls supporting RTL languages and localization.
