Progress Telerik UI for WinForms
The multi-column combobox control in Telerik UI for WinForms by Progress is a versatile combination of the RadTextBox editing field, combined with the power of RadDropDownList, which hosts a RadGridView in its drop-down list. The controls are tightly coupled to work seamlessly together and allow for looking up and selecting data from a multi-column list. The TextBox can be set to accept free-form data input, thus triggering the filtering mode, or can be read-only, forcing the user to select from the entries in the drop-down list.
Telerik MultiColumnComboBox provides rich design-time support functionality making customizations and configurations very easy. Some of the key capabilities are:
The control is shipped with a rich set of themes that allow you to easily build slick interfaces with the look-and-feel of some of the latest Windows and Office versions. The themes can be easily switched using a single property.
Our framework also features support for custom themes, which can be built from scratch to fit your exact visual demands by using the Visual Style Builder productivity tool.
Telerik ComboBox is also capable of displaying rich text formatting by using standard HTML tags, such as <i>, <b>, and <u>. This is supported on a framework level.
