wpf - 在 wpf 中启用和禁用按钮

Question

我有好几个 Buttons在屏幕上。一键点击 Button其余所有 Buttons应该禁用。有没有办法创建一个方法并设置所有启用和禁用Buttons而不是启用和禁用个人 Buttons .

Answer 1

此方法假定按钮位于同一个网格上，它反转每个按钮的启用状态，除了点击的按钮。

MainWindow.xaml

<Window x:Class="WpfApplication1.MainWindow"

        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="10,43,0,0" Name="button2" VerticalAlignment="Top" Width="75" Click="button_Click" />

MainWindow.xaml.cs

private void button_Click(object sender, RoutedEventArgs e)
{
    Button btn = (Button)sender;
    foreach (FrameworkElement  item in ((Panel)btn.Parent).Children )
    {
        if (item is Button)
        {
            if (btn.Name != item.Name)
                item.IsEnabled = !item.IsEnabled;
        }
    }
