IE8 WebGrid Performance Issus
posted

Hi,

I'm using Infragistics 10.1 for .Net 3.5 UltraWebGrid. When I test my web page in IE8, the performance is much slower than in IE7.

In my program, I loop through 200 records and finish around 17 sec, i.e. about 0.085 sec per record. But in IE 8, I need around 4 min, i.e. about 1.2 sec per record. The difference is really huge.

I think the problem is due to Javascript functions of UltraWebGrid, because I found that the grid.Rows.getRow(i) function alone already consumed 0.5 sec. I believe the getColumnByKey() function will take another 0.5 sec, but I didn't test it yet.

Do you guys have the same problem? Can anyone suggest a solution or workaround? The performance drop is terrible.

    Hi Adam,

    It has been a while since your post, however in case you still need assistance with this I would be glad to help.

    I am so far unable to replicate such long loading times for the records in UltraWebGrid using IE8. A sample illustrating the matter will be appreciated as it will allow us to examine the issue in more detail.

    Please do not hesitate to contact me if you require assistance.

    Best Regards,
