Tip
For more info, design guidance, and code examples, see Corner radius.
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 |
Always returns |
DispatcherQueue |
Gets the |
Filter |
Gets or sets the type of the filter applied to the CornerRadiusFilterConverter. |

Methods
ClearValue(DependencyProperty) |
Clears the local value of a dependency property. (Inherited from DependencyObject) |
Convert(Object, TypeName, Object, String) |
Converts the source CornerRadius by extracting only the fields specified by the Filter and leaving others set to 0. |
ConvertBack(Object, TypeName, 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) |
