我一直试图从我的应用程序中的工具包中获取新的颜色选择器,但没有成功......
以下是应该采用窗口背景颜色来填充当前颜色的示例代码,并且在新选择时,应该将背景颜色更改为所选颜色...
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="100" Width="200" xmlns:extToolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended"
Name="Window" Background="blue">
<Grid>
<extToolkit:ColorPicker Name="colorPicker1"
SelectedColor="{Binding ElementName=Window,Path=Background}"
CurrentColor="{Binding ElementName=Window,Path=Background}" />
</Grid>
</Window>
这是我在彩色标签上找到的所有文档...... http://elegantcode.com/2010/08/15/extended-wpf-toolkit-new-colorpicker-control/

这里的问题是Window.Background是Brush和SelectedColor,CurrentColor是Color。您可以使用转换器来实现此功能。
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:extToolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended"
xmlns:local="clr-namespace:WpfApplication1"
Title="MainWindow" Height="100" Width="200"
Name="Window" Background="blue">
<Window.Resources>
<local:BrushColorConverter x:Key="BrushColorConverter"/>
</Window.Resources>
<Grid>
<extToolkit:ColorPicker Name="colorPicker1"
SelectedColor="{Binding ElementName=Window,
Path=Background,
Converter={StaticResource BrushColorConverter}}"
CurrentColor="{Binding ElementName=Window,
Path=Background,
Converter={StaticResource BrushColorConverter}}" />
</Grid>
</Window>
和转换器
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Data;
using System.Windows.Media;
namespace WpfApplication1
{
public class BrushColorConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
SolidColorBrush brush = value as SolidColorBrush;
return brush.Color;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
Color color = (Color)value;
return new SolidColorBrush(color);
}
}
}

转换功能对我来说不起作用,最终这就是诀窍:
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return new SolidColorBrush((Color)value);
}

将设置用作中介。在Settings.settings中,创建string类型的用户范围参数。将其命名为BackColor1 然后为控件和元素的背景创建绑定,将它们都设置为相同的设置(如下所示)。优点是用户获得持久设置。我想要确切地说我测试它是一个网格行的背景,而不是一个窗口,但它应该工作相同。
