WPF容器将所有子控件转为只读

您可以使用提供值继承的附加属性来执行此操作:

public class ReadOnlyPanel
{
    public static readonly DependencyProperty IsReadOnlyProperty =
        DependencyProperty.RegisterAttached(
            "IsReadOnly", typeof(bool), typeof(ReadOnlyPanel),
            new FrameworkPropertyMetadata(false,
                FrameworkPropertyMetadataOptions.Inherits, ReadOnlyPropertyChanged));

    public static bool GetIsReadOnly(DependencyObject o)
    {
        return (bool)o.GetValue(IsReadOnlyProperty);
    }

    public static void SetIsReadOnly(DependencyObject o, bool value)
    {
        o.SetValue(IsReadOnlyProperty, value);
    }

    private static void ReadOnlyPropertyChanged(
        DependencyObject o, DependencyPropertyChangedEventArgs e)
    {
        if (o is TextBox)
        {
            ((TextBox)o).IsReadOnly = (bool)e.NewValue;
        }
        // other types here
    }
}

您可以在XAML中使用它,如下所示:

<StackPanel local:ReadOnlyPanel.IsReadOnly="{Binding IsChecked, ElementName=cb}">
    <CheckBox x:Name="cb" Content="ReadOnly"/>
    <TextBox Text="Hello"/>
</StackPanel>
