WPF Color Picker Implementation
提问by
I have to create a color picker in my WPF application. When I click on any color, the code of that color should come in a textbox. I googled a lot but found nothing matching my requirement. Please share if you have done like this before.
我必须在我的 WPF 应用程序中创建一个颜色选择器。当我单击任何颜色时,该颜色的代码应出现在文本框中。我用谷歌搜索了很多,但没有找到符合我要求的东西。如果您以前这样做过,请分享。

As Jodha said, you should use the Color Picker Control from the WpfToolkit Extended. Implementing the Color Picker Control is easy, simply do something like this:
正如 Jodha 所说,您应该使用 WpfToolkit Extended 中的颜色选择器控件。实现颜色选择器控件很容易,只需执行以下操作:
Put this in your Window object:
把它放在你的 Window 对象中:
xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"
And this wherever you want your color picker.
这就是您想要的颜色选择器。
<xctk:ColorPicker Name="ClrPcker_Background" SelectedColorChanged="ClrPcker_Background_SelectedColorChanged"></xctk:ColorPicker>
Then, all you have to do is use the SelectedColorChanged event to change the text in the textbox, like this:
然后,您所要做的就是使用 SelectedColorChanged 事件来更改文本框中的文本,如下所示:
private void ClrPcker_Background_SelectedColorChanged(object sender, RoutedPropertyChangedEventArgs<Color> e)
{
    TextBox.Text = "#" + ClrPcker_Background.SelectedColor.R.ToString() + ClrPcker_Background.SelectedColor.G.ToString() + ClrPcker_Background.SelectedColor.B.ToString();
}
Hope this helps!
希望这可以帮助!
