<summary>Represents a rule that checks for exceptions that are thrown during the update of the binding source property.</summary>
<remarks>
<format type="text/markdown"><.
## Examples
The <xref:System.Windows.Data.Binding.ValidationRules%2A> property takes a collection of <xref:System.Windows.Controls.ValidationRule> objects. The following example uses <xref:System.Windows.Controls.TextBox.Text%2A?displayProperty=nameWithType> as the binding target property and `StartPrice` (an integer) as the binding source property. When the user enters a value that cannot be converted to an integer, an exception is thrown, which causes the <xref:System.Windows.Controls.ExceptionValidationRule> to invalidate the target value.
:::code language="xaml" source="~/snippets/csharp/System.Windows/DataTemplate/Triggers/AddProductWindow.xaml" id="Snippetdefaultvalidation":::
By default, when there is a validation error, the <xref:System.Windows.Controls.TextBox> appears with a red border. Optionally, you can write a custom <xref:System.Windows.Controls.Validation.ErrorTemplate%2A> to specify how you want to notify the user when there is a validation error.
For more information about data validation, see [Data Binding Overview](/dotnet/framework/wpf/data/data-binding-overview).
For the complete sample, see [Data Binding Demo](https://go.microsoft.com/fwlink/?LinkID=163703).
