| Name | Description | |
|---|---|---|
 | DiscreteInt32KeyFrame() | Initializes a new instance of the DiscreteInt32KeyFrame class. |
| DiscreteInt32KeyFrame(Int32) | Initializes a new instance of the DiscreteInt32KeyFrame class with the specified ending value. |
| DiscreteInt32KeyFrame(Int32, KeyTime) | Initializes a new instance of the DiscreteInt32KeyFrame class with the specified ending value and key time. |
| Name | Description | |

 | CanFreeze | Gets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.) |
| DependencyObjectType | Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject.) |
| Dispatcher | Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.) |
| IsFrozen | Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.) |
| IsSealed | Gets a value that indicates whether this instance is currently sealed (read-only).(Inherited from DependencyObject.) |
| KeyTime | Gets or sets the time at which the key frame's target Value should be reached. (Inherited from Int32KeyFrame.) |
| Value | Gets or sets the key frame's target value. (Inherited from Int32KeyFrame.) |
| Name | Description | |
|---|---|---|

| GetType() | |
| GetValue(DependencyProperty) | Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.) |
| InterpolateValue(Int32, Double) | Returns the interpolated value of a specific key frame at the progress increment provided.(Inherited from Int32KeyFrame.) |
| InterpolateValueCore(Int32, Double) | Uses discrete interpolation to transition between the previous key frame value and the value of the current key frame. (Overrides Int32KeyFrame.InterpolateValueCore(Int32, Double).) |
| InvalidateProperty(DependencyProperty) | Re-evaluates the effective value for the specified dependency property(Inherited from DependencyObject.) |

| OnFreezablePropertyChanged(DependencyObject, DependencyObject) | Ensures that appropriate context pointers are established for a DependencyObjectType data member that has just been set.(Inherited from Freezable.) |
| OnFreezablePropertyChanged(DependencyObject, DependencyObject, DependencyProperty) | This member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code.(Inherited from Freezable.) |
| OnPropertyChanged(DependencyPropertyChangedEventArgs) | Overrides the DependencyObject implementation of OnPropertyChanged to also invoke any Changed handlers in response to a changing dependency property of type Freezable.(Inherited from Freezable.) |
| ReadLocalValue(DependencyProperty) | Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.) |
| ReadPreamble() | |
| 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.) |

  | IKeyFrame.Value | This API supports the product infrastructure and is not intended to be used directly from your code. See Value.(Inherited from Int32KeyFrame.) |
This class is used as part of a Int32KeyFrameCollection in conjunction with a Int32AnimationUsingKeyFrames to animate a Int32 property value along a set of key frames.
A key frame defines a segment of the Int32AnimationUsingKeyFrames to which it belongs. Each key frame has a target Value and a KeyTime. The KeyTime specifies the time at which the key frame's Value should be reached. A key frame animates from the target value of the previous key frame to its own target value. It starts when the previous key frame ends and ends when its own key time is reached.
Discrete key frames like DiscreteInt32KeyFrame create sudden "jumps" between values (no Interpolation). In other words, the animated property does not change until the key frame's key time is reached at which point the animated property goes suddenly to the target value.
