Create a PopupColorEdit
To add a PopupColorEdit to a Window, drag it from the Toolbox.
The following sample demonstrates how to create a PopupColorEdit using XAML markup.
<dxe:PopupColorEdit ColumnCount="10" ShowNoColorButton="True"
DefaultColor="Crimson" NoColorButtonContent="Empty Color"
MoreColorsButtonContent="Color picker" ChipSize="Medium"/>
Editor Value
You can specify the editor’s value using the Color property.
<Window ...
xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors">
<!-- Specify value using the PopupColorEdit.Color property -->
<dxe:PopupColorEdit Color="#ff396ba7"/>
To respond to changing the editor’s value, handle the BaseEdit.EditValueChanged event. To check the new value’s validity, handle the BaseEdit.Validate event.
Predefined Color Palettes
You can create gradient palettes from predefined sets of colors.
myPopupColorEdit.Palettes.Add(
CustomPalette.CreateGradientPalette(
"Verve",
PredefinedColorCollections.Verve
)
);
Custom Palettes
You can define your own color sets:
using DevExpress.Xpf.Editors;
...
List<Color> customColors = new List<System.Windows.Media.Color>() {
Color.FromRgb(170, 0, 0),
Color.FromRgb(0, 125, 0),
Color.FromRgb(0, 0, 170) };
myPopupColorEdit.Palettes.Add(new CustomPalette("Custom RGB Colors", customColors));
Built-in Color Picker
The PopupColorEdit.ShowMoreColorsButton property controls the availability of the More Colors button. Clicking this button invokes the built-in color picker tool. Color picker allows end-users to select the desired color visually or by specifying the precise values.
Configurable Palette Layout
You can specify the number of color columns in each palette using the PopupColorEdit.ColumnCount property. The PopupColorEdit.ChipSize property controls the size of the color chips.
Optional Default Color Button
You can define the default color using the PopupColorEdit.DefaultColor property. The PopupColorEdit.ShowDefaultColorButton property toggles the availability of the Default Color button.
Optional No Color Button
Setting the PopupColorEdit.ShowNoColorButton property to true enables the No Color button. The No Color button allows users to select an empty color.

This example shows how to create custom palettes and display them within the PopupColorEdit control.
