MouseBinding Class


Binds a MouseGesture to a RoutedCommand (or another ICommand implementation).

public ref class MouseBinding : System::Windows::Input::InputBinding
public class MouseBinding : System.Windows.Input.InputBinding
type MouseBinding = class
    inherit InputBinding
Public Class MouseBinding
Inherits InputBinding


The following example shows how to use a MouseBinding to bind a MouseGesture to a RoutedCommand.

<MouseBinding Gesture="Control+WheelClick"
              Command="ApplicationCommands.Open" />
MouseGesture OpenCmdMouseGesture = new MouseGesture();
OpenCmdMouseGesture.MouseAction = MouseAction.WheelClick;
OpenCmdMouseGesture.Modifiers = ModifierKeys.Control;

MouseBinding OpenCmdMouseBinding = new MouseBinding();
OpenCmdMouseBinding.Gesture = OpenCmdMouseGesture;
OpenCmdMouseBinding.Command = ApplicationCommands.Open;

Dim OpenCmdMouseGesture As New MouseGesture()
OpenCmdMouseGesture.MouseAction = MouseAction.WheelClick
OpenCmdMouseGesture.Modifiers = ModifierKeys.Control

Dim OpenCmdMouseBinding As New MouseBinding()
OpenCmdMouseBinding.Gesture = OpenCmdMouseGesture
OpenCmdMouseBinding.Command = ApplicationCommands.Open



A MouseBinding associates a MouseGesture with an ICommand implementation. RoutedCommand is the primary implementation of the ICommand interface for the WPF commanding system. In general, when the MouseGesture is executed, the command is invoked, although the command behavior is further influenced by command-specific factors such as the CanExecute value. For more information on commanding, see the Commanding Overview.

When defining a MouseBinding in Extensible Application Markup Language (XAML), there are two ways to specify the MouseGesture. The first way to establish a MouseBinding in XAML is to define the Gesture attribute of the MouseBinding element, which enables a syntax to specify mouse actions and modifiers as a single string; for example, "CTRL+LeftClick". The second way is to define the MouseAction attribute of the MouseBinding element. Both ways of setting the MouseGesture are equivalent and modify the same underlying object, but there will be a conflict if both are used. In the case when the MouseAction and the Gesture attributes are both set, the gesture is invalid. In general, it is recommended that you use only the Gesture attribute from XAML, even if you do not specify modifiers; this avoids ambiguity, provides the most streamlined syntax, and provides the most straightforward representation for serialization.

A MouseBinding can be defined on a specific object or at the class level by registering a RegisterClassInputBinding on the CommandManager class. The most typical way to define a MouseBinding is within the control template, setting the InputBindings property in XAML by declaring one or more MouseBinding or KeyBinding elements.



Initializes a new instance of the MouseBinding class.

MouseBinding(ICommand, MouseGesture)

Initializes a new instance of the MouseBinding class, using the specified command and mouse gesture.



Identifies the MouseAction dependency property.



Gets or sets the ICommand associated with this input binding.

(Inherited from InputBinding)

Gets or sets the command-specific data for a particular command.

(Inherited from InputBinding)

Gets or sets the target element of the command.

(Inherited from InputBinding)

Gets the DependencyObjectType that wraps the CLR type of this instance.

(Inherited from DependencyObject)

Gets the Dispatcher this DispatcherObject is associated with.

(Inherited from DispatcherObject)

Gets or sets the gesture associated with this MouseBinding.


Gets a value that indicates whether this instance is currently sealed (read-only).

(Inherited from DependencyObject)

Gets or sets the MouseAction associated with this MouseBinding.



Determines whether the calling thread has access to this DispatcherObject.

(Inherited from DispatcherObject)

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier.

(Inherited from DependencyObject)

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey.

(Inherited from DependencyObject)

Copies the base (non-animated) values of the properties of the specified object.


Copies the current values of the properties of the specified object.


Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.

(Inherited from DependencyObject)

Creates an instance of an MouseBinding.


Determines whether a provided DependencyObject is equivalent to the current DependencyObject.

(Inherited from DependencyObject)

Creates the instance a frozen clone of the specified Freezable by using base (non-animated) property values.


Creates the current instance a frozen clone of the specified Freezable. If the object has animated dependency properties, their current animated values are copied.


Gets a hash code for this DependencyObject.

(Inherited from DependencyObject)

Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject.

(Inherited from DependencyObject)

Gets the Type of the current instance.

(Inherited from Object)

Returns the current effective value of a dependency property on this instance of a DependencyObject.

(Inherited from DependencyObject)

Re-evaluates the effective value for the specified dependency property.

(Inherited from DependencyObject)

Creates a shallow copy of the current Object.

(Inherited from Object)

Invoked whenever the effective value of any dependency property on this DependencyObject has been updated. The specific dependency property that changed is reported in the event data.

(Inherited from DependencyObject)

Returns the local value of a dependency property, if it exists.

(Inherited from DependencyObject)
SetCurrentValue(DependencyProperty, Object)

Sets the value of a dependency property without changing its value source.

(Inherited from DependencyObject)
SetValue(DependencyProperty, Object)

Sets the local value of a dependency property, specified by its dependency property identifier.

(Inherited from DependencyObject)
SetValue(DependencyPropertyKey, Object)

Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property.

(Inherited from DependencyObject)

Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property.

(Inherited from DependencyObject)

Returns a string that represents the current object.

(Inherited from Object)

Enforces that the calling thread has access to this DispatcherObject.

(Inherited from DispatcherObject)
