IMPROVE. RadGridView - scrolling performance with many visual elements and using MouseWheel or scrollbar arrows
Create a grid with more than 20 columns and add 5K rows for example. Maximize the form and try to scroll with mouse wheel. You will notice that the scrolling performance is worse compared to the normal state of the form with less visible visual elements.

Workaround: this.radGridView1.EnableFastScrolling = true; and use the scrollbar's thumb

Second workaround: use paging:  https://docs.telerik.com/devtools/winforms/gridview/paging/overview Thus, you will display as many rows as possible to display on the screen per page. Instead of scrolling, you will navigate through pages.

Yes, it is duplicate. Merged in the other item.
Thanks.

EnableFastScrolling = true is no workaround for this.
I can't tell our customers to scroll the grid without the mouse wheel.

Will this be fixed in the upcoming version?
We already have multiple customer complaints about the scrolling performance of the grid.
