OK, so I'm not really sure what the problem is here:
private void Validate()
{
    ClearErrors("CustomerName");

    if (string.IsNullOrWhiteSpace(Customer.CustomerName))
    {
        AddError("CustomerName", "The Customer Name cannot be empty.");
    }
}
<TextBox Grid.Row="1" 
            Grid.Column="0"
            Text="{Binding Customer.CustomerName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}"
            IsEnabled="{Binding AreFieldsEnabled}">

<pre>
<Validation.ErrorTemplate>
    <ControlTemplate>
        <StackPanel>
            <AdornedElementPlaceholder x:Name="textBox" />
            <ItemsControl ItemsSource="{Binding}">
                <ItemsControl.ItemTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding ErrorContent}" Foreground="Red" />
                    </DataTemplate>
                </ItemsControl.ItemTemplate>
            </ItemsControl>
        </StackPanel>
    </ControlTemplate>
</Validation.ErrorTemplate>



The TextBox is bound to Customer.CustomerName. When I remove the text, the error is added, but I don't see anything. I'm guessing I'm not doing this right.
In theory, theory and practice are the same. But in practice, they never are.”
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
