In addition, this component defines an AllowNull property, which when set to True lets the user set the corresponding data field to NULL by simply pressing the Delete key. This custom combo box displays all of the standard colors and optionally the Windows system colors by name, color sample, or both. The control supports a default color and also a custom color, which when selected displays the color selection dialog box.
Additional properties allow a developer to easily determine the selected color.
TRzFontComboBox Help your users select that perfect font by using this component, which displays a list of font names, an icon indicating the type of each font, and optionally a sample of each font.

When a user selects an entry from the list, the item is moved to the top of the list, and when a user enters a new value in the edit portion, the new value is added to the top of the list. This list view component supports mouse wheel scrolling, Custom Framing , and additional display properties such as AlphaSortAll and FillLastColumn .
