FIX. RadGridView - performance should be improved when many cells are visibile (e.g. 50 rows and 30 columns)
Changing the DataSource or scrolling are slow.

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.
(Total attached files size should be smaller than 20mb. Allowed extensions: .zip, .rar, .jpg, .png, .gif)

Hello, 

RadGridView is built on top of TPF and the framework allows the creation of themeable controls as well as unlimited customizations and nesting of elements. We have tried several ways to improve the performance in the discussed scenario without much success. The performance issue is caused by a core limitation of the chosen approach. We are still trying to resolve it.

Regards,
Hristo
