WPF - Setting ToolTip MaxWidth

I avoid using Template because a lot things must be implement. So more elegant way to do that

<Style TargetType="ToolTip">    <Style.Resources>        <Style TargetType="ContentPresenter">            <Style.Resources>                <Style TargetType="TextBlock">                    <Setter Property="TextWrapping" Value="Wrap" />                </Style>            </Style.Resources>        </Style>    </Style.Resources>    <Setter Property="MaxWidth" Value="500" /></Style>

I realise that this is an old question, but no one seems to have suggested the most obvious and simplest solution to this problem yet. As such, I thought I'd add it here:

<Button>    <Button.ToolTip>        <ToolTip MaxWidth="400">            <TextBlock Text="{Binding Binding}" TextWrapping="Wrap" />        </ToolTip>    </Button.ToolTip></Button>

Following style of ToolTip is useful for me:

<Style TargetType="ToolTip" x:Key="InternalToolTipStyle">    <Setter Property="MaxWidth" Value="{Binding Path=(lib:ToolTipProperties.MaxWidth)}" />    <Setter Property="ContentTemplate">        <Setter.Value>            <DataTemplate>                <ContentPresenter Content="{TemplateBinding Content}"  >                    <ContentPresenter.Resources>                        <Style TargetType="{x:Type TextBlock}">                            <Setter Property="TextWrapping" Value="Wrap" />                        </Style>                    </ContentPresenter.Resources>                </ContentPresenter>            </DataTemplate>        </Setter.Value>    </Setter></Style>

With this style, tooltip of following button appears properly:

<Button><Button.ToolTip>    <StackPanel>        <TextBlock Style="{StaticResource firstText}" Text="aaaaaaaaaaaaa"/>        <TextBlock Style="{StaticResource secondText}" Text="bbbbbbbbbbbbb"/>            <TextBlock Bacground="Red" Text="ccccccccccccc"/>        </StackPanel></Button.ToolTip>
