Activate horizontal scrolling with mouse on ListView

listview, mouse, scroll, wpf

Solution

if you implement `IScrollInfo` you can override the `MouseWheelUp` to do `MouseWheelLeft` and down\right the in same way

edit (much more simple):

add to your ScrollViewer PreviewMouseWheel

private void ScrollViewer_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
        {
            if (e.Delta < 0) // wheel down
            {
                if (myScrollViewer.HorizontalOffset + e.Delta > 0)
                {
                    myScrollViewer.ScrollToHorizontalOffset(myScrollViewer.HorizontalOffset + e.Delta);  
                }
                else
                {
                    myScrollViewer.ScrollToLeftEnd();
                }
            }
            else //wheel up
            {
                if (myScrollViewer.ExtentWidth > myScrollViewer.HorizontalOffset + e.Delta)
                {
                    myScrollViewer.ScrollToHorizontalOffset(myScrollViewer.HorizontalOffset + e.Delta);  
                }
                else
                {
                    myScrollViewer.ScrollToRightEnd();
                }
            }

        }

xaml:

<ScrollViewer x:Name="myScrollViewer" HorizontalScrollBarVisibility="Visible" Mouse.PreviewMouseWheel="ScrollViewer_PreviewMouseWheel">

Problem

I've got a custom horizontal ListView with custom ScrollViewer inside it's template (created with Blend). I want it to scroll horizontally when using mouse scrolling wheel. How can I do that?
