Question

I have a property of datattype enum : like

public BreakLevel Level
{
    get { return level; }
    set { level = value; }
}

And enum defined :

  public enum BreakLevel
    {
        Warning, Fatal
    }

I want bind the neum property to the visibility of my border , somewhat like this:

Visibility=”{Binding BreakLevel.Fatal}”
so is it possible?

<Border CornerRadius="4" BorderThickness="1"  BorderBrush="#DAE0E5"  
Visibility="{Binding DataContext.IsError, Converter={StaticResource BoolToVisibilityConverter}, RelativeSource={RelativeSource TemplatedParent}}" >

I think you can just create a BreakLevelToVisibilityConverter and bind just like the example you provided.

I’m assuming that the DataContext of your border is set to an instance of a class that has a property of type ‘BreakLevel’ (we’ll call this property ‘BreakLvlProperty’).

The code below will then show the border if the value of BreakLvlProperty is BreakLevel.Fatal

Converter:

public class BreakLevelToVisibilityConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if ((BreakLevel)value == BreakLevel.Fatal)
            return Visibility.Visible;
        else
            return Visibility.Hidden;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return null;
    }
}

XAML:

<TopLevelWindowOrControl.Resources>
    <local:BreakLevelToVisibilityConverter x:Key="BreakLevelToVisibilityConverter" />
</TopLevelWindowOrControl.Resources>

<Border Visibility="{Binding Path=BreakLvlProperty, Converter={StaticResource BreakLevelToVisibilityConverter}" />
