Question

假设我有一个功能区选项卡名称A（name =“_ tabA”）和B（name =“_ tabB”）。如何动态禁用或隐藏选项卡A或B？

我将VS2010与RibbonControlsLibrary.dll一起使用。

Answer 1

<ribbon:RibbonTab Visibility="{Binding ShowThisRibbonTab, Converter=...}">

其中ShowThisRibbonTab是ViewModel的属性，转换器最有可能是BooleanToVisibilityConverter。

或者，如果你没有做MVVM，你可以给它一个名字并设置可见性

Answer 2

没有MVVM

我可以使用_tabA.Visibility = Visibility.Collapsed或Visibility.Visible轻松隐藏/显示。

使用MVVM

.xaml.cs代码

使类继承自INotifyProperty
在修改属性时设置属性以引发事件
设置DataContext。
制作转换器代码。

主要代码如下

public partial class MainWindow : RibbonWindow, INotifyPropertyChanged
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = this;
    }

    public const string NamePropertyName = "VisibleA"; 
    private bool _visibleA = true;
    public bool VisibleA
    {
        get
        {
            return _visibleA;
        }
        set
        {
            _visibleA = value;
            RaisePropertyChanged(NamePropertyName); 
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    private void RaisePropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    } 
}

转换器代码如下

[ValueConversion(typeof(bool), typeof(Visibility))]
internal class CheckVisibleA : System.Windows.Data.IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        bool? val = value as bool?;
        string param = parameter as string;

        if (value != null)
        {
            if (val == true)
            {
                return Visibility.Visible;
            }
        }

        return Visibility.Collapsed;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

此XAML有两个功能区选项卡：_ribboHome和_ribbonHelp。并且“VisibleA”的属性控制可见性。当我单击该复选框时，VisibleA属性打开/关闭，_ribbonHome相应地进行visbile /折叠。

<ribbon:Ribbon DockPanel.Dock="Top" Title="teusje.wordpress.com" >
    <ribbon:RibbonTab Header="Home" Name="_ribbonHome" Visibility="{Binding Path=VisibleA, Converter={StaticResource CheckVisibleA}, ConverterParameter=Show}">
        <ribbon:RibbonGroup Name="Clipboard" Header="Clipboard">
            <ribbon:RibbonButton Command="{StaticResource hwc}" CommandParameter="Hello, smcho" Label="Copy" LargeImageSource="Images/LargeIcon.png" /> 

        </ribbon:RibbonGroup>
    </ribbon:RibbonTab>
    <ribbon:RibbonTab Header="Help">
        <ribbon:RibbonGroup Name="_ribbonHelp" Header="Help this">
            <ribbon:RibbonButton Command="{StaticResource hwc}" CommandParameter="Hello, smcho" Label="Copy Help" LargeImageSource="Images/LargeIcon.png"/>
            <ribbon:RibbonCheckBox IsChecked="{Binding Path=VisibleA}"/>
        </ribbon:RibbonGroup>
    </ribbon:RibbonTab>

如何动态隐藏/禁用WPF功能区选项卡？
