Properties

Name Description
AllowCancelAsyncOperations Gets or sets whether users can cancel asynchronous “Post Changes” operations.
CanFreeze Gets a value that indicates whether the object can be made unmodifiable. Inherited from Freezable.
CreateCommand Invokes the dialog edit form to allow users to add a new row to the control.
CreateEditItemViewModelCommand Gets or sets a command that specifies a View Model for the edit operation. The behavior executes this command before the edit form dialog appears.
DeleteCommand Deletes selected rows from the control.
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.
EditTemplate Gets or sets a template that defines editors in the dialog edit form. Use the CreateEditItemViewModel event or the CreateEditItemViewModelCommand to specify the template’s data context.
HasAnimatedProperties Gets a value that indicates whether one or more AnimationClock objects is associated with any of this object’s dependency properties. Inherited from Animatable.
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.
KeyProperty Gets or sets a key field that you can use to find rows during edit operations.
RowDoubleClickCommand Executes the CreateCommand or UpdateCommand depending on the selected row. This command is designed to allow you to bind it to the TableView.RowDoubleClickCommand / TreeListView.RowDoubleClickCommand.
UpdateCommand Invokes the dialog edit form for the selected row.
ValidateRowCommand Gets or sets a command that validates input values, checks database constraints, and saves changes to the database. The behavior executes this command after a user saves changes made in the edit form dialog.
ValidateRowDeletionCommand Gets or sets a command that validates data, checks database constrains, and deletes rows. The behavior executes this command when user deletes selected rows.

Methods

Name Description
ApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior) Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used. Inherited from Animatable.
ApplyAnimationClock(DependencyProperty, AnimationClock) Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used. Inherited from Animatable.
BeginAnimation(DependencyProperty, AnimationTimeline, HandoffBehavior) Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the specified HandoffBehavior is used. Inherited from Animatable.
BeginAnimation(DependencyProperty, AnimationTimeline) Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the SnapshotAndReplace handoff behavior is used. Inherited from Animatable.
CheckAccess() Determines whether the calling thread has access to this DispatcherObject. Inherited from DispatcherObject.
ClearValue(DependencyProperty) Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. Inherited from DependencyObject.
ClearValue(DependencyPropertyKey) Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. Inherited from DependencyObject.
Clone() Creates a modifiable clone of this Animatable, making deep copies of this object’s values. When copying this object’s dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values. Inherited from Animatable.
CloneCore(Freezable) protected Makes the instance a clone (deep copy) of the specified Freezable using base (non-animated) property values. Inherited from Freezable.
CloneCurrentValue() Creates a modifiable clone (deep copy) of the Freezable using its current values. Inherited from Freezable.
CloneCurrentValueCore(Freezable) protected Makes the instance a modifiable clone (deep copy) of the specified Freezable using current property values. Inherited from Freezable.
CoerceValue(DependencyProperty) 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.
CreateInstance() protected Initializes a new instance of the Freezable class. Inherited from Freezable.
Equals(Object, Object) static Determines whether the specified object instances are considered equal. Inherited from Object.
Equals(Object) Determines whether a provided DependencyObject is equivalent to the current DependencyObject. Inherited from DependencyObject.
Freeze() Makes the current object unmodifiable and sets its IsFrozen property to true. Inherited from Freezable.
Freeze(Freezable, Boolean) protected static If the isChecking parameter is true, this method indicates whether the specified Freezable can be made unmodifiable. If the isChecking parameter is false, this method attempts to make the specified Freezable unmodifiable and indicates whether the operation succeeded. Inherited from Freezable.
GetAnimationBaseValue(DependencyProperty) Returns the non-animated value of the specified DependencyProperty. Inherited from Animatable.
GetAsFrozen() Creates a frozen copy of the Freezable, using base (non-animated) property values. Because the copy is frozen, any frozen sub-objects are copied by reference. Inherited from Freezable.
GetAsFrozenCore(Freezable) protected Makes the instance a frozen clone of the specified Freezable using base (non-animated) property values. Inherited from Freezable.
GetCurrentValueAsFrozen() Creates a frozen copy of the Freezable using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference. Inherited from Freezable.
GetCurrentValueAsFrozenCore(Freezable) protected Makes the current instance a frozen clone of the specified Freezable. If the object has animated dependency properties, their current animated values are copied. Inherited from Freezable.
GetHashCode() Gets a hash code for this DependencyObject. Inherited from DependencyObject.
GetLocalValueEnumerator() Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. Inherited from DependencyObject.
GetType() Gets the Type of the current instance. Inherited from Object.
GetValue(DependencyProperty) Returns the current effective value of a dependency property on this instance of a DependencyObject. Inherited from DependencyObject.
InvalidateProperty(DependencyProperty) Re-evaluates the effective value for the specified dependency property. Inherited from DependencyObject.
MemberwiseClone() protected Creates a shallow copy of the current Object. Inherited from Object.
OnChanged() protected Called when the current Freezable object is modified. Inherited from Freezable.
OnFreezablePropertyChanged(DependencyObject, DependencyObject, DependencyProperty) protected This member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code. Inherited from Freezable.
OnFreezablePropertyChanged(DependencyObject, DependencyObject) protected Ensures that appropriate context pointers are established for a DependencyObjectType data member that has just been set. Inherited from Freezable.
OnPropertyChanged(DependencyPropertyChangedEventArgs) protected Overrides the DependencyObject implementation of OnPropertyChanged(DependencyPropertyChangedEventArgs) 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() protected Ensures that the Freezable is being accessed from a valid thread. Inheritors of Freezable must call this method at the beginning of any API that reads data members that are not dependency properties. Inherited from Freezable.
ReferenceEquals(Object, Object) static Determines whether the specified Object instances are the same instance. Inherited from Object.
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.
ShouldSerializeProperty(DependencyProperty) protected Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property. Inherited from DependencyObject.
ShouldSerializeStoredWeakReference(DependencyObject) static Specifies whether a dependency object should be serialized. Inherited from Animatable.
ToString() Returns a string that represents the current object. Inherited from Object.
VerifyAccess() Enforces that the calling thread has access to this DispatcherObject. Inherited from DispatcherObject.
WritePostscript() protected Raises the Changed event for the Freezable and invokes its OnChanged() method. Classes that derive from Freezable should call this method at the end of any API that modifies class members that are not stored as dependency properties. Inherited from Freezable.
WritePreamble() protected Verifies that the Freezable is not frozen and that it is being accessed from a valid threading context. Freezable inheritors should call this method at the beginning of any API that writes to data members that are not dependency properties. Inherited from Freezable.

Events

Name Description
Changed Occurs when the Freezable or an object it contains is modified. Inherited from Freezable.
CreateEditItemViewModel Occurs before a user invokes the dialog edit form. This event allows you to specify a view model for the edit operation.
ValidateRow Occurs after a user saves changes made in the dialog edit form. This event allows you to validate values, check database constraints, and save changes to the database.
ValidateRowDeletion Occurs after a user removes selected rows from the control. This event allows you to validate rows, check database constraints, and delete rows from the database.
