MultiBinding.ValidatesOnExceptions Property

Gets or sets a value that indicates whether to include the ExceptionValidationRule.

Namespace:  System.Windows.Data
Assembly:  PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation
public bool ValidatesOnExceptions { get; set; }
<object ValidatesOnExceptions="bool" .../>

Property Value

Type: System.Boolean
true to include the ExceptionValidationRule; otherwise, false.

Setting this property provides an alternative to using the ExceptionValidationRule element explicitly. The ExceptionValidationRule is a built-in validation rule that checks for exceptions that are thrown during the update of the source property. If an exception is thrown, the binding engine creates a ValidationError with the exception and adds it to the Validation.Errors collection of the bound element. The lack of an error clears this validation feedback, unless another rule raises a validation issue.

For more information about the validation process for MultiBinding objects, see the ValidationRules property.

ValidatesOnExceptions is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.
