CornerRadiusFilterConverter Class

Definition

Namespace:

Microsoft.UI.Xaml.Controls.Primitives

Converts an existing CornerRadius struct to a new CornerRadius struct, with filters applied to extract only the specified fields, leaving the others set to 0.

This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).

Examples

See the XAML Controls Gallery sample app for examples of WinUI features and controls.

If you have the XAML Controls Gallery app installed, open the app to see the controls in action.

If you don't have the XAML Controls Gallery app installed, get the WinUI 2.x version from the Microsoft Store.

You can also view, clone, and build the XAML Controls Gallery source code from GitHub (switch to the WinUI 3 Preview branch for WinUI 3 Preview controls and features).

The following example shows how to use the CornerRadiusFilterConverter element.

<ControlTemplate TargetType="Button">
    <Grid>
        <Grid.Resources>
            <CornerRadiusFilterConverter Filter="Top" x:Name="TopCornersFilter" />
        </Grid.Resources>
        <Border Background="{TemplateBinding Background}"
                CornerRadius="{Binding  CornerRadius,
                RelativeSource={RelativeSource TemplatedParent},
                Converter={StaticResource TopCornersFilter}}"
                Padding="{TemplateBinding Padding}">
            <ContentPresenter />
        </Border>
    </Grid>
</ControlTemplate>

Remarks

Use the CornerRadiusFilterConverter with a Binding or TemplateBinding to create a new CornerRadius struct from an existing one, extracting only some of the fields, leaving the others set to 0.

Constructors

CornerRadiusFilterConverter()

Initializes a new instance of the CornerRadiusFilterConverter class. This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).

Properties

Filter	Gets or sets the type of the filter applied to the CornerRadiusFilterConverter. This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).
FilterProperty	Identifies the Filter dependency property. This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).
Scale	Gets or sets the scale multiplier applied to the CornerRadiusFilterConverter. This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).
ScaleProperty	Identifies the Scale dependency property. This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).

Methods

Convert(Object, TypeName, Object, String)	Converts the source CornerRadius by extracting only the fields specified by the Filter and leaving others set to 0. This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).
ConvertBack(Object, TypeName, Object, String)	Not implemented. This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).
