eXontrol Software - ComboBox ActiveX, NET Control

ComboBox object

Built from the ground up using 100% ATL-based code, the ExComboBox represents some of the most advanced combobox technology available in the Component marketplace. The ExComboBox has more things that you can imagine: ADO, DAO support, multiple columns, incremental search feature, mouse wheel support, locked and unlocked columns, multiple edit controls and more. It acts like a combobox and has three styles: Simple, DropDown and DropDownList. The dropped list control can acts like a simple list box, like a list with multiple columns, like a standard tree or like a multicolumn tree control. Every cell or item can apply different font attributes, background or foreground color, can display a caption using more rows, can display an icon, and more. Cut down your development time and add value to your application with this intelligent, easy to use search control. The ComboBox object supports the following properties and methods:
