Wpf toggle button converter
The following example creates a CheckBox set to an indeterminate state. A control that inherits from ToggleButton determines its behavior when this property is null. When the IsThreeState property is set to true, a user can click a CheckBox to pick three possible states. The following table describes the three states of a CheckBox. If IsThreeState is false, you can still programmatically set this property to null to put the CheckBox in an indeterminate state, but the user cannot set the CheckBox to the indeterminate state through the user interface UI.
If you set this property to null on a RadioButton , the RadioButton is unchecked. Search related threads. Remove From My Forums. Asked by:. Archived Forums. Expression Blend SketchFlow. Sign in to vote. Hi, this is probably a stupid question but anyway, I need help with this issue!

Adds a routed event handler for a specified routed event, adding the handler to the handler collection on the current element.
Specify handledEventsToo as true to have the provided handler be invoked even if the event is handled elsewhere. Equivalent WinUI method: Microsoft. Positions child objects and determines a size for a UIElement. Parent objects that implement custom layout for their child elements should call this method from their layout override implementations to form a recursive layout update. Provides the behavior for the "Arrange" pass of layout.
Classes can override this method to define their own "Arrange" pass behavior. Sets pointer capture to a UIElement. Once captured, only the element that has capture will fire pointer-related events.
Enables a UIElement subclass to expose child elements that assist with resolving touch targeting. Returns any base value established for a dependency property, which would apply in cases where an animation is not active. Returns the BindingExpression that represents the binding on the specified property. Enables a UIElement subclass to expose child elements that take part in Tab focus. Retrieves the named element in the instantiated ControlTemplate visual tree.
Returns the current effective value of a dependency property from a DependencyObject. When implemented in a derived class, enables per-state construction of a visual tree for a control template in code, rather than by loading XAML for all states at control startup. Invalidates the arrange state layout for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously. Invalidates the measurement state layout for a UIElement.
Invalidates the viewport state for a UIElement that is used to calculate the effective viewport. Typically, objects that implement custom layout for their layout children call this method from their own MeasureOverride implementations to form a recursive layout update. Provides the behavior for the "Measure" pass of the layout cycle. Classes can override this method to define their own "Measure" pass behavior. Invoked whenever application code or internal processes such as a rebuilding layout pass call ApplyTemplate.
In simplest terms, this means the method is called just before a UI element displays in your app. Override this method to influence the default post-template logic of a class. Called before the BringIntoViewRequested event occurs.
Called before the CharacterReceived event occurs. Invoked when the value of the Content property changes. Invoked when the value of the ContentTemplate property changes. Invoked when the value of the ContentTemplateSelector property changes. When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure.
Override this method to implement how layout and logic should behave when items are removed from a class-specific content or children property. Called before the DoubleTapped event occurs. Called before the DragEnter event occurs. Called before the DragLeave event occurs.
Called before the DragOver event occurs. Called before the Drop event occurs. Called before the GotFocus event occurs. Called before the Holding event occurs. Called when a keyboard shortcut or accelerator is processed in your app. Override this method to handle how your app responds when a keyboard accelerator is invoked. Called before the KeyDown event occurs. Called before the KeyUp event occurs.
Called before the LostFocus event occurs. Called before the ManipulationCompleted event occurs. Called before the ManipulationDelta event occurs. Called before the ManipulationInertiaStarting event occurs. Called before the ManipulationStarted event occurs. Called before the ManipulationStarting event occurs. Called before the PointerCanceled event occurs. Called before the PointerCaptureLost event occurs.
Called before the PointerEntered event occurs. Called before the PointerExited event occurs. Called before the PointerMoved event occurs. Called before the PointerPressed event occurs. Called before the PointerReleased event occurs.
Called before the PointerWheelChanged event occurs. Called before the PreviewKeyDown event occurs. Called before the PreviewKeyUp event occurs. Called just before a keyboard shortcut or accelerator is processed in your app. Invoked whenever application code or internal processes call ProcessKeyboardAccelerators.
Override this method to influence the default accelerator handling. Called before the RightTapped event occurs. Called before the Tapped event occurs. Called when the ToggleButton receives toggle stimulus. Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. Releases pointer captures for capture of one specific pointer by this UIElement.
Removes the specified routed event handler from this UIElement. Typically the handler in question was added by AddHandler. Attaches a binding to a FrameworkElement , using the provided binding object. Sets the local value of a dependency property on a DependencyObject. Initiates a request to the XAML framework to bring the element into view within any scrollable regions it is contained within.
Initiates a request to the XAML framework to bring the element into view using the specified options. Returns a transform object that can be used to transform coordinates from the UIElement to the specified object. Attempts to invoke a keyboard shortcut or accelerator by searching the entire visual tree of the UIElement for the shortcut. Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback.
Ensures that all positions of child objects of a UIElement are properly updated for layout. Equivalent WinUI event: Microsoft. Occurs when StartBringIntoView is called on this element or one of its descendants. Fires when a ToggleButton is checked. Occurs when a context input gesture continues into a manipulation gesture, to notify the element that the context flyout should not be opened. Occurs when the value of the FrameworkElement. DataContext property changes.
