Question

我有一个Enum，我想绑定到Tab控件。基本上我希望枚举成员名称（描述）填充选项卡标题和选定的选项卡以设置枚举值。

我想要做的是选择选项卡，控制枚举的值。因此，当我选择Tab“DC Hipot”时，它将枚举值设置为DCW，当我选择“Resistance”选项卡时，它将枚举值设置为LOWOHM。然后我希望反转为真，如果枚举值改变，则选择相应的选项卡。因此，例如，如果枚举值更改为LOWOHM，则所选选项卡将更改为“电阻”。

我已阅读此帖子Binding TabControl to an enum，但它没有提供完整的解决方案。我没有看到其中任何一个实际上与Tab Control有关。

这是一个带单选按钮和我想用Tabs和Enum做的int的例子。 Simple WPF RadioButton Binding?

特定枚举是MV_Main.SelectedTestStepForUI.vTestType。

这是我的MainWindows.xaml

这是主视图模型，MV_Main及其依赖项

[AddINotifyPropertyChangedInterface]  //** Fodo
class MV_Main
{

    public MV_Test SelectedTestStepForUI { get; set; }

    public IEnumerable<TestType> TestTypes
    {
        get
        {
            return Enum.GetValues(typeof(TestType))
                .Cast<TestType>();
        }
    }


    public MV_Main()
    {          
        SelectedTestStepForUI = new MV_Test();
    }

}

public enum TestType
{
    [Description("AC Hipot")]
    ACW,
    [Description("DC Hipot")]
    DCW,
    [Description("Resistance")]
    LOWOHM
}

[AddINotifyPropertyChangedInterface] //** Fodo
public class MV_Test
{
    public TestType vTestType { get; set; }
    //** DCW Items
    public double RampTime { get; set; }
    public double DwellTime { get; set; }
    public double Voltage { get; set; }
    public double MaxLeakageLimit { get; set; }
    public double MinLeakageLimit { get; set; }
    public double BreakDownLimit { get; set; }
    public double ArcDetectionTimeLimit { get; set; }
    public double ArcDetectionCurrentLimit { get; set; }

    //** LOWOHM Items
    public double TestTimeResistance { get; set; }
    public double MinResistance { get; set; }
    public double MaxResistance { get; set; }
}

Answer 1

我终于找到了一个使用IValueConverter

的解决方案

这是我的转换器代码

public class EnumSelectedConverter : IValueConverter
{
    public object Convert(object value, Type targetType,
        object parameter, System.Globalization.CultureInfo culture)
    {
        if (value == null || parameter == null) return false;
        TestType vmType = (TestType) value;
        TestType viewType = (TestType) parameter;

        return vmType == viewType;
    }

    public object ConvertBack(object value, Type targetType,
        object parameter, System.Globalization.CultureInfo culture)
    {
        if (value == null || parameter == null) return false;

        bool isSelected = (bool) value;
        if (!isSelected) return false;

        TestType vTestType = (TestType) parameter;

        return vTestType;
    }
}

然后在我的XAML

中

<TabControl Height="101" Width="294">
    <TabItem Header="Resistance" IsSelected="{Binding SelectedTestStepForUI.vTestType, Converter={StaticResource EnumSelectedConverter}, ConverterParameter={x:Static local:TestType.LOWOHM}}">
    </TabItem>
    <TabItem Header="DC Hipot" IsSelected="{Binding SelectedTestStepForUI.vTestType, Converter={StaticResource EnumSelectedConverter}, ConverterParameter={x:Static local:TestType.DCW}}">
    </TabItem>
</TabControl>

注意：Make to将它添加到XAML文件的顶部也像这样

<Window.Resources>
    <local1:EnumSelectedConverter x:Key="EnumSelectedConverter" />
</Window.Resources>

将枚举绑定到TabControl选项卡标题和选定选项卡
