CornerRadiusFilterConverter Class

Definition

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.

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.

Properties

Dispatcher

Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

(Inherited from DependencyObject)
DispatcherQueue

Gets the DispatcherQueue that this object is associated with. The DispatcherQueue represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread.

(Inherited from DependencyObject)
Filter

Gets or sets the type of the filter applied to the CornerRadiusFilterConverter.

FilterProperty

Identifies the Filter dependency property.

Scale

Gets or sets the scale multiplier applied to the CornerRadiusFilterConverter.

ScaleProperty

Identifies the Scale dependency property.

Methods

ClearValue(DependencyProperty)

Clears the local value of a dependency property.

(Inherited from DependencyObject)
Convert(Object, Type, Object, String)

Converts the source CornerRadius by extracting only the fields specified by the Filter and leaving others set to 0.

ConvertBack(Object, Type, Object, String)

Not implemented.

GetAnimationBaseValue(DependencyProperty)

Returns any base value established for a dependency property, which would apply in cases where an animation is not active.

(Inherited from DependencyObject)
GetValue(DependencyProperty)

Returns the current effective value of a dependency property from a DependencyObject.

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if a local value is set.

(Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)

Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance.

(Inherited from DependencyObject)
SetValue(DependencyProperty, Object)

Sets the local value of a dependency property on a DependencyObject.

(Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)

Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback.

(Inherited from DependencyObject)
