保存在一个WPF点击的按钮用户颜色设置 [英] Saving user color settings of a clicked Button in WPF
问题描述
我有救了我的按钮的一些性质有点问题。的按钮是小，并用各种颜色。当我preSS一个按钮，一些指定的颜色正在发生变化......，我想救他们下一次启动时。文本框的值，我可以救他们，但这个...我不能。
I have a little problem with saving some properties of my Buttons. The Buttons are small and with a variety of colors. When i press one button, some specified colors are changing... and i want to save them for the next start up. The textbox values i can save them but this ...i can't.
code：
public MainWindow()
{
InitializeComponent();
//blueColor.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));
//this.Property = Properties.Settings.Default.userColor;
}
private void blueColor_Click(object sender, RoutedEventArgs e)
{
var bc = new BrushConverter();
Main.Background = (Brush)bc.ConvertFrom("#FF007CE4");
startButton.Foreground = (Brush)bc.ConvertFrom("#FF007CE4");
closeButton.Foreground = (Brush)bc.ConvertFrom("#FF007CE4");
Properties.Settings.Default.userColor = true;
Properties.Settings.Default.Save();
}
private void purpleColor_Click(object sender, RoutedEventArgs e)
{
var bc = new BrushConverter();
Main.Background = (Brush)bc.ConvertFrom("#FF8701B9");
startButton.Foreground = (Brush)bc.ConvertFrom("#FF8701B9");
closeButton.Foreground = (Brush)bc.ConvertFrom("#FF8701B9");
}
我想我需要在最后单击按钮进行保存，因为我已经配发的颜色，也许是.RaiseEvent可以帮助在这里。
I think I need the last clicked Button to be saved because I have allot of colors and maybe the .RaiseEvent can help here.
这是它的样子：
3的那些小按钮：
- 白色
- 蓝色
- 红色
是用于改变节目的外观。在每次启动时，默认是回来了。
are for changing the look of the program. At every start, the default is back.
推荐答案
您可以将颜色存储为一个简单的字符串和的TypeConverter 自动将其转换为键入刷。下面是一个例子。
You can store the color as a simple string and TypeConverter automatically converts it to type Brush. Below is an example.
这是XAML绑定默认值：
Binding default value from XAML:
xmlns:properties="clr-namespace:WorkWithSettings.Properties"
<Button Width="100" Height="30"
Background="{Binding Source={x:Static properties:Settings.Default}, Path=Setting, Mode=TwoWay}" />
从code设置值：
Set value from code:
private void Button_Click(object sender, RoutedEventArgs e)
{
WorkWithSettings.Properties.Settings.Default.Setting = "#FF007CE4";
}
注：设置 - 这是字符串

编辑：
下面我会告诉你一个例子，我希望能帮助你。
Below I'll show you an example, that I hope will help you.
所以，进入该项目的设置：项目 - ＆GT;属性 - ＆GT;参数。这将打开约一个窗口：
So, go into the settings of the project: Project -> Properties -> Parameters. This opens a window of approximately:
在这里，我们有一个属性 ButtonColor ，在设置中定义。比如，我把按钮，它改变的背景下，依赖于pressed按钮的颜色。
Here we have a property ButtonColor, defined in the settings. For example, I took the Button, which changes the background, depending on the color of the pressed button.
为了财产背景与设置同步做的，所以：
In order to property Background the synchronize with settings to do, so:
<Button Width="100" Height="30"
Content="TestButton"
Background="{Binding Source={x:Static properties:Settings.Default}, Path=ButtonColor, Mode=TwoWay}" />
白色，默认背景色。现在，设置在按钮的背景颜色，我们改变了参数设置，如：
The default background color of white. Now, to set the background color at the button, we change the parameter settings, like this:
private void Blue_Click(object sender, RoutedEventArgs e)
{
WorkWithSettings.Properties.Settings.Default.ButtonColor = "Blue";
}
要保存更改设置，您需要调用一个方法保存（）：
To save changes to the settings, you need to call a method Save():
private void Save_Click(object sender, RoutedEventArgs e)
{
WorkWithSettings.Properties.Settings.Default.Save();
}
现在，在下次启动程序时，颜色会是最后设置的。
Now, the next time you start the program, the color will be the one that was set last.
