This is a demonstration on the use of ToolStripDropDown class by creating a color picker combobox. Honestly I'm surprised that .Net framework doesn't come with this control, as any rich text editor application would need one of these in their toolbar. As this is my first attempt at C# programming my first thought for accomplishing the task of creating the ColorComboBox was to create a control that would inherit from a CheckBox which when checked would create and display a form without a title bar, where the form would house the flat radio buttons representing the colors.
