一、XAML 集成方式
1 、在WPF窗体上使用，xml：加入空间命名引用
xmlns:ui1="clr-namespace:ArcGIS.Desktop.Internal.Mapping.Symbology;assembly=ArcGIS.Desktop.Mapping" xmlns:uil="http://schemas.xceed.com/wpf/xaml/toolkit"2、在<Grid>中加入
<Grid><!-- 颜色选择器控件 --><uil:ColorPicker Name="MyColorPicker" SelectedColor="{Binding SelectedColor}" Width="100" Height="30"HorizontalAlignment="Left"VerticalAlignment="Top"/>
</Grid>3、选择事件
Private Sub MyColorPicker_SelectedColorChanged(sender As Object, e As RoutedPropertyChangedEventArgs(Of Color?)) Handles MyColorPicker.SelectedColorChangedDim picker As ColorPicker = DirectCast(sender, ColorPicker)Dim selectedColor As Color? = picker.SelectedColor
End Sub
)
