WPF Sliderf follow cursor - wpf

Question

I have slider :
<Slider x:Name="DesktopAudioSlider"
HorizontalAlignment="Stretch"
Margin="0,0,5,0">
I need behavior like in UWP Slider , that follow the cursor when it click. I cant use events because use MVVM , tried to convert sender and eventargs to tuple and pass to command , but there is no way how to pass MouseEventargs to converter.
Converter :
class SliderArgsToTupleConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if(parameter is MouseEventArgs)
{
return new Tuple<object, MouseEventArgs>(value, parameter as MouseEventArgs);
}
else
{
throw new ArgumentException();
}
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
Command :
this.SlideMouseMoveCommand = new RelayCommand<Tuple<object, MouseEventArgs>>(SlideMouseMoveExecute);
Trigger :
<i:EventTrigger EventName="MouseMove">
<i:InvokeCommandAction Command="{Binding MixerViewModel.SlideMouseMoveCommand, Source={StaticResource Locator}}"
CommandParameter="{Binding ElementName=DesktopAudioSlider , ConverterParameter={}}"
</i:EventTrigger>

There is no way how to pass two arguments in command , i found the one solution - add behavior.
public class SliderMoveBehavior : Behavior<Slider>
{
protected override void OnAttached()
{
base.OnAttached();
AssociatedObject.MouseMove += SliderMouseMove;
}
protected override void OnDetaching()
{
base.OnDetaching();
AssociatedObject.MouseMove -= SliderMouseMove;
}
private void SliderMouseMove(object sender, MouseEventArgs e)
{
if (e.LeftButton == MouseButtonState.Pressed)
{
Point position = e.GetPosition(AssociatedObject);
double d = 1.0d / AssociatedObject.ActualWidth * position.X;
var p = AssociatedObject.Maximum * d;
AssociatedObject.Value = (int)p;
}
}
}
In XAML :
<Slider x:Name="PlaybackSpeedSlider">
<i:Interaction.Behaviors>
<behaviors:SliderMoveBehavior/>
</i:Interaction.Behaviors>
</Slider>
