[CLOSED] GridPanel slow rendering in IE8

[Leonid_Veriga]

We have an issue with a GridPanel performance in IE8. The grid loads about 10 sec (see attached example). Do you have any suggestions how to improve the performance?

Hello,

Please create a standalone ASPX page and post directly here wrapping in [CODE] tags. We will be happy to investigate.

Thank you.

The problem that you bind 100 rows per page, each row in seperate group because group field has unique value per row (100 groups), for each group you create Button (100) buttons

If you remove buttons creation then performance much better. Also you do not destroy buttons before grid view refresh, on each refresh you create new buttons but old buttons are not destroyed (it causes memory leakages because javascript instance of each button stays in memory), I suggest to replace button by anchor html element (or by css button, image and etc )

Also you can use ImageCommand to add group commands

It's because there is a test data in the example. Really we have 2-5 rows in each group.
We used CommandColumn before but it was very slow. Then we replaced it to ActionColumn and custom buttons to improve performance but it's still slow.

We'll try it.

Thanks.
