我们在做winform程序时常常会用到一个颜色选择框,但在WP7中没有提供这个类供我们调用,今天看到一个开源项目coding4Fun,下面就介绍一下这个六边形的颜色选择框使用方法:
首先下载到我们所要用到dll包,地址会在博文后面给出。在VS2010新建一个项目,然后添加引用
然后在MainPage.xaml文件头添加命名空间声明

接下来在需要添加六边形颜色选择框的地方直接添加以下代码:
<c4fControls:ColorHexagonPicker />
效果如下:
Coding4Fun针对这个六边形颜色提取器提供了以下几个属性:
  • Color
  这是一个颜色独立属性,它决定了当面颜色选择器中的颜色选择结果。类型为Color
  • ColorBrightnessSteps
  颜色亮度步长,类型为int
  • ColorDarknessSteps
  颜色暗度步长,类型为int
  • ColorSize
  颜色选择矩形框的大小,类型Double
  • GreyScaleSteps
  灰度值的步长,类型int
  • SolidColorBrush
  当前选择的颜色画刷
下面是一个例子,大家可以对照代码看看效果:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <c4fControls:ColorHexagonPicker  ColorSize="10" ColorBrightnessSteps="3" Margin="-147,22,147,75" Height="510" Width="456" />
            <c4fControls:ColorHexagonPicker  ColorSize="10" ColorBrightnessSteps="5" Margin="9,22,-9,75" Height="510" Width="456" />
            <c4fControls:ColorHexagonPicker  ColorSize="10" ColorDarknessSteps="3" Margin="-125,210,125,-113" Height="510" Width="456" />
            <c4fControls:ColorHexagonPicker  ColorSize="10" ColorDarknessSteps="5" Margin="53,210,-53,-113" Height="510" Width="456" />
            <c4fControls:ColorHexagonPicker  ColorSize="10" GreyScaleSteps="3" Margin="-125,416,125,-319" Height="510" Width="456" />
            <c4fControls:ColorHexagonPicker  ColorSize="10" GreyScaleSteps="5" Margin="76,441,-76,-344" Height="510" Width="456" />
</Grid>
要设置没有六边形颜色选择区域,请看下面代码:
<c4fControls:ColorHexagonPicker ColorSize="20" ColorDarknessSteps="0" ColorBrightnessSteps="0" Margin="94,260,-94,-163" Height="510" Width="456" />
接下来是一个颜色画刷绑定的例子。
前台绑定:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <c4fControls:ColorHexagonPicker ColorSize="20" Name="ColorPicker" Margin="-6,6,6,91" Height="510" Width="456" />
            <Rectangle Height="80" HorizontalAlignment="Left" Fill="{Binding ElementName=ColorPicker,Path=SolidColorBrush}" Margin="143,366,0,0" Name="rectangle1" Stroke="Black" StrokeThickness="1" VerticalAlignment="Top" Width="146" />
            <TextBlock FontSize="30" Height="40" HorizontalAlignment="Left" Margin="12,366,0,0" Name="textBlock1" Text="颜色绑定:" VerticalAlignment="Top" Width="125" />
</Grid>
利用ColorChanged事件进行后台绑定实现:
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <c4fControls:ColorHexagonPicker ColorSize="20" Name="ColorPicker" ColorChanged="ColorPicker_ColorChanged" Margin="-6,6,6,91" Height="510" Width="456" />
            <Rectangle Height="80" HorizontalAlignment="Left" Margin="143,366,0,0" Name="rectangle1" Stroke="Black" StrokeThickness="1" VerticalAlignment="Top" Width="146" />
            <TextBlock FontSize="30" Height="40" HorizontalAlignment="Left" Margin="12,366,0,0" Name="textBlock1" Text="颜色绑定:" VerticalAlignment="Top" Width="125" />
</Grid>
 private void ColorPicker_ColorChanged(object sender, Color color)
        {
            this.rectangle1.Fill = new SolidColorBrush(color);
        }
