Width
The size of the color boxes in the palette is automatically calculated according to the Columns property to fit the given Width property. Each box is of equal width and height. By default, the size of each color box is 15 by 15 pixels. The example below shows two RadColorPicker definitions where both have 5 Columns, but the first uses the default width and the second has a Width of 200 pixels.
