I have a the following code for a ScrollViewer in my Silverlight app. The BasketSymbolsView control contains controls that have custom double click triggers applied to them.

Is it possible to change the amount that the WPF ScrollViewer scrolls? I am simply wondering if it's possible to change the scrollviewer so that when using the mouse wheel or the scrollviewer arrows, the amount of incremental scrolling can be changed. ...
I’ve got this strange problem whereby the content within a scroll viewer increases in size, the scroll viewer then shows is horizontal scroll bar.

I have a ListBox. It has internal ScrollViewer, so I can scroll ListBox content with mouse wheel. It works fine until I set item template that contains another ListBox (in fact, I have 4 nested ListBoxes =)). Problem is that internal ListBox's ScrollViewer steals wheeling event. Is there any easy way to prevent this behavior? I had Li...

I have a silverlight listbox that is being used as a search result box. I'm using dynamic searching (keyups in the search box cause the events to fire to filter this list box's contents).
