The BindingValidationError event is raised when the binding engine creates and removes a validation error.

The following example shows how to set a binding to catch validation errors. When a BindingValidationError event is reported, use the ValidationErrorEventArgs to present the error Action information graphically to the user.


private void StackPanel_BindingValidationError(object sender, 
    ValidationErrorEventArgs e)
{
    if (e.Action == ValidationErrorEventAction.Added)
    {
        MyTextBox.Background = new SolidColorBrush(Colors.Red);

    }
    else if (e.Action == ValidationErrorEventAction.Removed)
    {
        MyTextBox.Background = new SolidColorBrush(Colors.White);
    }
}



<StackPanel BindingValidationError="StackPanel_BindingValidationError" >
    <StackPanel.Resources>
        <my:Bills x:Name="MyBills"/>
    </StackPanel.Resources>
    <TextBox x:Name="MyTextBox" Width="50" Margin="10">
        <TextBox.Text>
            <Binding Mode="TwoWay" Source="{StaticResource MyBills}" 
                     Path="Amount" NotifyOnValidationError="true" 
                     ValidatesOnExceptions="true"/>
        </TextBox.Text>
    </TextBox>
    <Button Height="50" Width="150" Content="Click To Update Source"/>
</StackPanel>
