In a response to one comment in our first article about the weather control we decided to update it. Now it is easier to slide item by item. It is not the best implementation but it works with a little tuning. Just remember if you change the item's sizes you must adjust the width of the control. The width should meet the requirements of this equation.
(control.Width - LeftButton.Width - RightButton.Width ) % (control.Height / ItemHeight * ItemWidth) = 0
Not convenient but we will work on that until the next version.
