如何指定一個特定的內容，如「飛機」的WPF按鈕？

Question

按鈕是以編程方式包含每個文本字符串。也許，有一些方法可以找到像這種情況下的屬性的控件。

這是我的代碼，它以編程方式製作按鈕和鏈接事件的代碼。

如果用戶按下A按鈕（飛機），按鈕的顏色會變成黃色。但是，如果用戶在按下A按鈕後按下B按鈕（Car），該怎麼辦？我想知道如何將A按鈕的顏色從黃色更改爲正常，並將B按鈕的顏色從正常更改爲黃色。這就是爲什麼我需要指出一個按鈕的內容。

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; 
}

沒有你的代碼，答案是不可行的。根據您的具體情況，這是一個可行的解決方案。

做這樣的事情：

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 
}
