View 10 RepliesI'm developing a WPF app in which I have a ScrollViewer with grid (16 ColumnDefinitions all auto width) with an image assigned to each column.The effect I want to create is when the mouse enters a area on the left of the ScrollViewer the images will scroll to the left and when the mouse enters an area on the right of the ScrollViewer they scroll to the right. The scrollbars will be hidden. The areas to the left and right are defined by two rectangles with mouseEnter and mouseLeave events. My code behind utilises a timer to programatically scroll the ScrollViewer leftor right.[code]
