Use System.Windows.Interactivity

…xmlns:i=http://schemas.microsoft.com/expression/2010/interactivity…

<Slider    
    <i:Interaction.Triggers>    
        <i:EventTrigger EventName="ValueChanged">
            <i:InvokeCommandAction    
                Command="{Binding MyCommand}"    
                CommandParameter="{Binding Text, ElementName=textBox}"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>
</Slider>

Make sure your project references the assembly System.Windows.Interactivity.
