## Methods

[Convert(object, Type, object, CultureInfo)](Phoenix.BuilderUIClient.BooleanInvertConverter.Convert.md#Phoenix_BuilderUIClient_BooleanInvertConverter_Convert_System_Object_System_Type_System_Object_System_Globalization_CultureInfo_)

Negates a value

[ConvertBack(object, Type, object, CultureInfo)](Phoenix.BuilderUIClient.BooleanInvertConverter.ConvertBack.md#Phoenix_BuilderUIClient_BooleanInvertConverter_ConvertBack_System_Object_System_Type_System_Object_System_Globalization_CultureInfo_)

Negates a value

[ProvideValue(IServiceProvider)](Phoenix.BuilderUIClient.BooleanInvertConverter.ProvideValue.md#Phoenix_BuilderUIClient_BooleanInvertConverter_ProvideValue_System_IServiceProvider_)

Returns this object as the value of the target property for this markup extension. This allows you to do something like this:

```csharp
Value="{Binding IsOpen, Mode=OneWay, Converter={converter:BoolInvertConverter}}"

```

instead of having to pull in the converter as a static resource.
