  Hi,
  
  I am trying to control the number of rows/columns scrolled when using Apple magic mouse or touchpad in a laptop. Current scrolling speed is way too high and it starts annoying the user. As I see canvas scrolling is controlled by SpreadJS code, I would like a way to reduce the number of rows/columns scrolled.
  
  Thank You

  Hi Saurabh,

  With Spread.Sheets there is no direct property or method to control the number of Rows /columns scrolled. You can set the top row or left column in code by handling the TopRowChanged/LeftColumnChanged events:
