disable mouse wheel on itemscontrol in wpf

This can be accomplished via attached behaviors.

Edit: Here is the linked solution:

"So instead I came up with the following IgnoreMouseWheelBehavior. Technically it’s not ignoring the MouseWheel, but it is “forwarding” the event back up and out of the ListBox. Check it."

/// <summary>
/// Captures and eats MouseWheel events so that a nested ListBox does not
/// prevent an outer scrollable control from scrolling.
/// </summary>
public sealed class IgnoreMouseWheelBehavior : Behavior<UIElement>
{

  protected override void OnAttached( )
  {
     base.OnAttached( );
      AssociatedObject.PreviewMouseWheel += AssociatedObject_PreviewMouseWheel ;
  }

  protected override void OnDetaching( )
  {
      AssociatedObject.PreviewMouseWheel -= AssociatedObject_PreviewMouseWheel;
      base.OnDetaching( );
  }

  void AssociatedObject_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
  {

      e.Handled = true;

      var e2 = new MouseWheelEventArgs(e.MouseDevice,e.Timestamp,e.Delta);
      e2.RoutedEvent = UIElement.MouseWheelEvent;

      AssociatedObject.RaiseEvent(e2);

  }

}

And here’s how you would use it in XAML.

<ScrollViewer Name="IScroll">
    <ListBox Name="IDont">
        <i:Interaction.Behaviors>
            <local:IgnoreMouseWheelBehavior />
        </i:Interaction.Behaviors>
    </ListBox>
</ScrollViewer>

Where the i namespace is:

The answer you have referenced is exactly what is causing your problem, the ListBox (which is composed of among other things a ScrollViewer) inside your ScrollViewer catches the MouseWheel event and handles it, preventing it from bubbling and thus the ScrollViewer has no idea the event ever occurred.

Use the following extremely simple ControlTemplate for your ListBox to demonstrate (note it does not have a ScrollViewer in it and so the MouseWheel event will not be caught) The ScrollViewer will still scroll with the mouse over the ListBox.

<UserControl.Resources>
     <ControlTemplate x:Key="NoScroll">
         <ItemsPresenter></ItemsPresenter>
     </ControlTemplate>
</UserControl.Resources>

<ScrollViewer>
    <SomeContainerControl>
        <.... what ever other controls are inside your ScrollViewer>
        <ListBox Template="{StaticResource NoScroll}"></ListBox>
    <SomeContainerControl>
</ScrollViewer>

You do have the option of capturing the mouse when it enters the ScrollViewer though so it continues to receive all mouse events until the mouse is released, however this option would require you to delgate any further mouse events to the controls contained within the ScrollViewer if you want a response...the following MouseEnter MouseLeave event handlers will be sufficient.

private void ScrollViewerMouseEnter(object sender, MouseEventArgs e)
{
    ((ScrollViewer)sender).CaptureMouse();
}

private void ScrollViewerMouseLeave(object sender, MouseEventArgs e)
{
    ((ScrollViewer)sender).ReleaseMouseCapture();
}

Neither of the workarounds I have provided are really preferred however and I would suggest rethinking what you are actually trying to do. If you explain what you are trying to achieve in your question I'm sure you will get some more suggestions...
