Hi,

I have a RadMenu in a masterpage
and a radgrid with 2k rows in a different page.

Scrolling is really slow when viewing the grid, when disabling EnableEmbeddedSkins in RadMenu everything works fine, but offcourse the menu is not skinned.

What should i do to make this work?

Cheers!

Hi kizza,

This side effect might be related to WebResource caching - when your website is in debug mode (<compilation debug="true" /> in web.config) files streamed by WebResource.axd are not cached by the browser.

Here is a nice blog post on that matter: 
http://ocegtech.blogspot.com/2006/06/aspnet-20-webresourceaxd-and-browser.html

In a word everything should be ok once the site is not in debug mode (<compilation debug="false" />).

In additon, have in mind that the VS internal web server (a.k.a Cassini) does not use browser's cache.

Let me know whether this helps.

Best wishes,
Paul

Hi, debug is already on false.

BTW, i only have this problem in IE7 but not in FF. Maybe this helps.

Hi kizza,

Does the problem appear with other skins?Disabling the skin prevents RadMenu from including the corresponding skin CSS file. However it is not clear why that CSS file may cause the performance issue. Is there any live url where we can observe this behavior? This would greatly help us troubleshoot the problem. If this is not possible you can open a support ticket and send us a sample project which replicates the performance issue. Thanks.

Looking forward to your reply,
Albert

I had a problem when I had a subitem on a menu where IE would hang for about 5 seconds and consume one CPU.

I determined that it was my SpyBot add-in.
