This article lists the supported features by RadDomainUpDown:

  • Data Binding: via the DataSource property you can bind to a collection of custom objects. Additional information is available in the Data Binding.
  • Unbound Mode: it is possible to populate the Items collection manually either at design time or programmatically.
  • Auto-Complete: the boolean AutoComplete property indicates whether the auto-complete behavior will be enabled or not while typing in the editable part. As the user types, the next item in the list that matches the user input is automatically appended to the characters the user has already typed.

  • ReadOnly: when read-only mode is enabled, the user should not be allowed to type in the editor, still selecting items should be possible.

  • Right-to-Left: RadDomainUpDown fully supports right-to-left (RTL) language locales. You can enable/disable the right-to-left support using RightToLeft enumeration, which has the following members:

    Yes: Content is aligned from right to left.

    No: Content is aligned from left to right.

    Inherit: Direction will be determined by the parent control.
