scroll not enabled in TTIWDBAdvWebGrid

My TTIWDBAdvWebGrid has 25+ columns and I have the scroll set to persistent and style = scAlways. The scrollbar is visible but not enabled. I tried setting the scroll into view property to True but that didnt help. 

What could be the reason that scroll is not enabled. Also is there a column limit to the TTIWDBAdvWebGrid?



- Please make sure to set the UseFullWidth property to False to enable Horizontal scrolling and/or UseFullHeight to False to enable Vertical scrolling.

- There is no column limit for the TTIWDBAdvWebGrid.
