Quick Start Example

<!-- Basic ColorPickerPalette setup -->
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:syncfusion="http://schemas.syncfusion.com/wpf" 
        Title="ColorPickerPalette Sample">
    <Grid>
        <!-- Default dropdown mode with theme and standard colors -->
        <syncfusion:ColorPickerPalette x:Name="colorPickerPalette" 
                                       Color="Red"
                                       GenerateThemeVariants="True"
                                       GenerateStandardVariants="True"
                                       RecentlyUsedPanelVisibility="Visible"
                                       Width="60" 
                                       Height="40" />
    </Grid>
</Window>

C# Code-Behind:

using Syncfusion.Windows.Tools.Controls;

public partial class MainWindow : Window {
    public MainWindow() {
        InitializeComponent();

        // Handle color selection
        colorPickerPalette.SelectedBrushChanged += ColorPickerPalette_SelectedBrushChanged;
    }

    private void ColorPickerPalette_SelectedBrushChanged(object sender, SelectedBrushChangedEventArgs e) {
        var newColor = e.NewColor;
        var newBrush = e.NewBrush;
        // Apply color to UI elements
    }
}

Common Patterns

• Color Panel Customization: Set ThemePanelVisibility, StandardPanelVisibility, RecentlyUsedPanelVisibility, MoreColorOptionVisibility to control which panels appear
• Custom Colors Collection: Bind CustomColorsCollection property to ObservableCollection<CustomColor> and set SetCustomColors="True"
• Split Mode with Command: Set Mode="Split" and bind SelectedCommand for button behavior with dropdown access
• Expanded Palette Mode: Set Mode="Palette" to show palette always visible; adjust BorderWidth/BorderHeight for color item sizing

See appearance-customization.md and events-interactions.md for complete examples.

Key Properties

Common Use Cases

• Text Color Picker: Dropdown mode with standard/theme colors + SelectedBrushChanged to apply formatting
• Shape Fill Selector: Split mode with custom brand colors + SelectedCommand binding
• Theme Color Picker: Palette mode with GenerateThemeVariants="True" to show color variants
• Color History Panel: Enable RecentlyUsedPanelVisibility="Visible" for quick access to recent colors
