Constructors

Name Description
ValidationService() Initializes a new instance of the ValidationService class.

Fields

Name Description
AllowAccessibilityAlertsProperty static Identifies the AllowAccessibilityAlerts attached property.
HasValidationErrorProperty static Identifies the HasValidationError attached property.
IsValidationContainerProperty static Identifies the IsValidationContainer attached property.
ValidationErrorsProperty static Identifies the ValidationErrors attached property.
ValidationServiceProperty static Identifies the ValidationService attached property.

Properties

Name Description
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.
IsSealed Gets a value that indicates whether this instance is currently sealed (read-only). Inherited from DependencyObject.

Methods

Name Description
AddEditor(DependencyObject) For internal use.
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.
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.
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.
GetAllowAccessibilityAlerts(DependencyObject) static Get the value of the ValidationService.AllowAccessibilityAlerts attached property to a specified ValidationService.
GetHashCode() Gets a hash code for this DependencyObject. Inherited from DependencyObject.
GetHasValidationError(DependencyObject) static Get the value of the ValidationService.HasValidationError attached property to a specified ValidationService.
GetIsValidationContainer(DependencyObject) static Get the value of the ValidationService.IsValidationContainer attached property to a specified ValidationService.
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.
GetValidationErrors(DependencyObject) static Get the value of the ValidationService.ValidationErrors attached property to a specified ValidationService.
GetValidationService(DependencyObject) static Get the value of the ValidationService.ValidationService attached property to a specified ValidationService.
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.
OnPropertyChanged(DependencyPropertyChangedEventArgs) protected 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.
ReadLocalValue(DependencyProperty) Returns the local value of a dependency property, if it exists. Inherited from DependencyObject.
ReferenceEquals(Object, Object) static Determines whether the specified Object instances are the same instance. Inherited from Object.
RemoveEditor(DependencyObject) For internal use.
SetAllowAccessibilityAlerts(DependencyObject, Boolean) static Set the value of the ValidationService.AllowAccessibilityAlerts attached property to a specified ValidationService.
SetCurrentValue(DependencyProperty, Object) Sets the value of a dependency property without changing its value source. Inherited from DependencyObject.
SetIsValidationContainer(DependencyObject, Boolean) static Set the value of the ValidationService.IsValidationContainer attached property to a specified ValidationService.
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.
ToString() Returns a string that represents the current object. Inherited from Object.
UpdateEditor(DependencyObject) For internal use.
VerifyAccess() Enforces that the calling thread has access to this DispatcherObject. Inherited from DispatcherObject.
