Recently I had seen a website called http://www.innovasys.com which has some products which are very useful. Combo Plus is one such user interface control. We all know that Combo Box control is one of the mostly used tool in the tool box of any programmer. But there are certain limitations with this combobox.
Innovasys ComboPlus is an extended replacement for the standard ComboBox control, providing a wealth of additional features which make it easier for you to program and allow you to deliver more functionality in less time.
In addition to standard combo box., Combo Plus has some additional features like Auto Complete, Image Support, XP themes, Drive lists, Check boxes, History etc.
