WPFCustomControls::Converters::VisibilityConverter Class Reference

---

Detailed Description

Converts between boolean values and the Visibility enum.

By default, the VisibilityConverter converts from a true boolean value to Visibility.Visible, and from false to Visibility.Collapsed. To convert false to Visibility.Hidden, specify Visibility.Hidden as the Binding ConverterParameter.

The easiest way to use the VisibilityConverter in XAML is as a markup extension (assuming xmlns:c="clr-namespace:WPFCustomControls.Converters;assembly=WPFCustomControls").

        <Element Value="{Binding Path=SomePath, Converter={c:VisiblityConverter}>
