I found the solution:

<Style x:Key="MyTextBoxStyle"
        BasedOn="{StaticResource TextBoxPlusBaseStyle}"
        TargetType="{x:Type hc:TextBox}">
    <Setter Property="ToolTip" Value="{Binding Text, RelativeSource={RelativeSource Self}}" />
    <!--  Hide the validation error message, this solution does not work for ComboBox.  -->
    <Setter Property="Validation.ErrorTemplate" Value="{x:Null}" />
    <Setter Property="b:TripleClickToSelectAllBehavior.Enabled" Value="True" />
    <Setter Property="hc:InfoElement.ShowClearButton" Value="{Binding IsReadOnly, Converter={StaticResource Boolean2BooleanReConverter}, RelativeSource={RelativeSource Mode=Self}}" />
    <Setter Property="hc:TitleElement.TitlePlacement" Value="Left" />


    <Style.Triggers>
        <Trigger Property="Validation.HasError" Value="True">
            <Setter Property="ToolTip" Value="{Binding (Validation.Errors), RelativeSource={RelativeSource Self}, Converter={StaticResource ValidationErrorsToolTipConverter}}" />
        </Trigger>
    </Style.Triggers>
</Style>
