Defining the Colors

RadColorPicker provides simple, yet flexible ways for defining colors in the color palette. There are 3 ways to define the colors in the palette:

  • Using the Preset property - a user can choose from a number of predefined (embedded) palettes. See the available predefined palettes.
  • Defining the Items collection - this allows a user to set his own colors in the color palette
  • Using the Preset property and the Items collection - you can extend the colors of a predefined palette by combining multiple palettes or adding custom colors to an existing palette.
