Answer 1

Put a TextBlock inside your label and set TextTrimming to CharacterEllipsis or WordEllipsis

<Label>
     <TextBlock TextTrimming="CharacterEllipsis">Hello World</TextBlock>
</Label>

Hell no! This is what you hope for, but you know they couldn't have made it that easy! Really cool feature! – Adroit

For some vague reason (is anything not vague in wpf?) this is working in my designer, but not at runtime – Peer

Nevermind, I needed to assign text to the textblock and not use label.Content anymore in my code. – Peer

Answer 2

It's also possible to use AccessText within the Label like this:

<StackPanel Orientation="Horizontal">
<Label VerticalAlignment="Center" Width="50"
        Target="{Binding ElementName=txtName}">
    <AccessText Text="_First Name" TextTrimming="CharacterEllipsis"  />
</Label>
<TextBox Name="txtName" VerticalAlignment="Center" Width="120"/>

With this solution the access key for a control (e.g. Alt+F) still works.
