C# Class Watchdog.Validation.Core.Internal.ElementValidationHandler

A manager for a single FrameworkElement. This is the lowest-level in Watchdog, where the controls are forced into error with an artifical dummy binding between two do-nothing DependencyProperty which are attached to the FrameworkElement and marked as invalid.

Public Methods

Method	Description
Clear ( ) : void	Clears the errorHostingBindingExpr of any validation errors.
CreateValError ( ConversionError e ) : void	Creates the val error.
ElementValidationHandler ( FrameworkElement element ) : System	Initializes a new instance of the ElementValidationHandler class. Sets of a WeakReference to the given element. The rest of the invalid mechanisms are not initialized until the first time we need to invalid the element.
GetValidationSource ( DependencyObject obj ) : string	Gets the validation source property value.
GetValidationTarget ( DependencyObject obj ) : string	Gets the validation target property value.
SetValidationSource ( DependencyObject obj, string value ) : void	Sets the validation source property value.
SetValidationTarget ( DependencyObject obj, string value ) : void	Sets the validation target property value.
Show ( string message ) : void	Shows the specified message. This is accomplished by marking the errorHostingBindingExpr as invalid with a ValidationError containing the given message.

Private Methods

Method	Description
EnsureBinding ( ) : void	Checks for existence (and creates if necessary) the rules and bindings need to flag the control as invalid.

Property Details

ValidationSourceProperty public static property

Registers the ValidationSource attached DependencyProperty. This property does nothing but serve as one end of a binding that we use to mark the FrameworkElement as invalid.

public static DependencyProperty,System.Windows ValidationSourceProperty
return	System.Windows.DependencyProperty

ValidationTargetProperty public static property

Registers the ValidationTarget attached DependencyProperty. This property does nothing but serve as one end of a binding that we use to mark the FrameworkElement as invalid.

public static DependencyProperty,System.Windows ValidationTargetProperty
return	System.Windows.DependencyProperty
