Hello Robert,
Thank you for posting in our community.
In order to ensure that I will provide you with better and more accurate support I will need some additional information regarding your scenario.
Could you please let me know what is the reason why in the rendered event you are setting the overflow-x property of the scrolling container to auto? I am asking because initially, only one column in your grid is displayed. Since autofitLastColumn property is set to true by default this column will extend to the entire width of the grid. In this scenario no horizontal scrollbar is needed. If you resize the column later and its width exceeds the width of the grid a horizontal scrollbar appears by default and you could scroll all the way to the end of this scrollbar. Having this in mind I was wondering what is the purpose of showing this scrollbar in the rendered event of the igGrid and additionally setting hscroller_container to be hidden?
If I comment the code in the rendered event the igGrid behaves as expected on my side. I am attaching your modified sample for your reference.
I am looking forward to hearing from you.
This was a workaround suggested by someone in your support when we could not see a horizontal scroll bar for a fixed height grid.
