[Solved] Slow Horizontal Scrolling

[Arash Rahimi]

I am currently using scrolling feature of RadGrid (Q2 2009). The problem I have is with the very slow performance of its horizontal scrolling experience in a scenario where my grid has around 20 columns. I searched for similar issues in the forum and found out that other people had the similar problem in the specific case of having one or more frozen columns. Well! In my scenario, I don't have any frozen columns but the scrolling speed is noticably slow.

At least, I think in the case of no frozen columns, horizontal scrolling should not have any performance problem.

Is there anything I can do to fix this issue?

Hello Arash,

To optimize the performance in your case, consider reducing the number of visible column as much as possible (either hiding some of the columns or removing them completely and extracting their values on the client using key values), enable paging or virtual scrolling for grid.
