RadComboBox is an enhanced alternative to the standard Windows Forms combo box control.

In addition to standard Windows Forms functionaity RadComboBox features:

  • RadComboBox's visual appearance can be themed for complete visual customization and consistency with other controls. You can load predefined themes or use Visual Style Builder to create your own custom theme.


  • You have the ability to associate images and text descriptions with individual items in the drop-down list. Item and description fonts can be configured separately. The relationship of the text and image can be configured so that the image is first, text is first, text is on top or the image is on top. Images can have transparency and can be of any size.
