如何指示具有特定内容（如“飞机”）的 WPF 按钮？

Question

按钮以编程方式包含每个文本字符串。也许，有一些方法可以找到像这种情况下具有其属性的控件。

这是我以编程方式制作按钮的代码和链接事件的代码。

如果用户按下 A 按钮（飞机），按钮的颜色变成黄色怎么办。但是，如果用户在按下 A 按钮后按下 B 按钮（汽车）怎么办？我想知道如何将 A 按钮的颜色从黄色更改为正常，将 B 按钮的颜色从正常更改为黄色。这就是为什么我需要用它的内容来指示一个按钮。

for (int k = 0; k < Overviews.Length; k++)
{
    Button btnoverviewcontent = new Button();

    ToolTip tt = new ToolTip();
    tt.Content = "Press button if you want to modify or delete";
    btnoverviewcontent.ToolTip = tt;

    btnoverviewcontent.Cursor = Cursors.Hand;

    SolidColorBrush mySolidColorBrush = new SolidColorBrush();
    mySolidColorBrush.Color = Color.FromArgb(255, 101, 173, 241);
    btnoverviewcontent.Background = mySolidColorBrush;

    btnoverviewcontent.Effect = new DropShadowEffect
    {
        Color = new Color { A = 255, R = 0, G = 0, B = 0 },
        Direction = 315,
        ShadowDepth = 5,
        Opacity = 1
    };

    btnoverviewcontent.Padding = new Thickness(3, 3, 3, 3);
    btnoverviewcontent.HorizontalContentAlignment = System.Windows.HorizontalAlignment.Stretch;
    TextBlock textBlock = new TextBlock()
    {
        Text = Overviews[k],
        TextAlignment = TextAlignment.Left,
        TextWrapping = TextWrapping.Wrap,

    };

    btnoverviewcontent.Content = textBlock;
    btnoverviewcontent.BorderThickness = new Thickness(0, 0, 0, 0);
    btnoverviewcontent.FontStretch = FontStretches.UltraExpanded;
    btnoverviewcontent.Margin = new Thickness(5, 5, 5, 5);

    WrapPanelGreen.Children.Add(btnoverviewcontent);
    btnoverviewcontent.Click += new RoutedEventHandler(OnOverviewClick);
}  

void OnOverviewClick(object sender, RoutedEventArgs args)
{

    buttonOverviewmodification.Visibility = Visibility.Visible;
    buttonOverviewdeletion.Visibility = Visibility.Visible;

    Button btn = (Button)sender;
    DoubleAnimation animation = new DoubleAnimation(1, TimeSpan.FromMilliseconds(350));
    buttonOverviewmodification.BeginAnimation(Image.OpacityProperty, animation);
    buttonOverviewdeletion.BeginAnimation(Image.OpacityProperty, animation);

    SolidColorBrush mySolidColorBrush = new SolidColorBrush();
    mySolidColorBrush.Color = Color.FromArgb(255, 253, 253, 10);
    (sender as Button).Background = mySolidColorBrush;
}

没有您的代码，答案是不可行的。根据您所拥有的，这是一个可行的解决方案。

做这样的事情：

private void OnOverviewClick(object sender, RoutedEventArgs e)
{
    // for all buttons in WrapPanelGreen, reset background to default value we used
    foreach (var child in WrapPanelGreen.Children)
    {
        var b = child as Button;
        if (b != null)
        {
            SolidColorBrush mySolidColorBrush = new SolidColorBrush();
            mySolidColorBrush.Color = Color.FromArgb(255, 101, 173, 241);

            b.Background = mySolidColorBrush;
        }
    }

    // the rest of your code
}
