wpf Convert a boolean to visibility value


Example

This example hides the red box (border) if the checkbox is not checked by making use of an IValueConverter.

Note: The BooleanToVisibilityConverter used in the example below is a built-in value converter, located in the System.Windows.Controls namespace.

XAML:

<Window x:Class="StackOverflowDataBindingExample.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <BooleanToVisibilityConverter x:Key="VisibleIfTrueConverter" />
    </Window.Resources>
    <StackPanel>
        <CheckBox x:Name="MyCheckBox"
                  IsChecked="True" />
        <Border Background="Red" Width="20" Height="20"
                Visibility="{Binding Path=IsChecked,ElementName=MyCheckBox, Converter={StaticResource VisibleIfTrueConverter}}" />
    </StackPanel>
</Window>
