Hello While the expression system is quite powerfully, however on some elements it seems to be quite cpu intensive.
I tested binding via setExpressions together with jQuery, IE defaults to JScript for expression, nothing that heavy, but my firebug lite console filled quite fast with debug messages. Other Expressions didn't created these problems on other websites yet. You really don't need to worry about quirks mode (Sample, mixed Websites), you could try something like this: expression( eval(document.compatMode && document.compatMode=='CSS1Compat') ? My planed way to fix the IE problem is to have a jQuery like interface, so you would use $(someelements).ieFixLayout(); You may want to look at my current test code: http://www.bytetransfer.de/projects/jquery/ I still have problems that that IE decide to change the way how offsetWidth works when switching between 'auto' and a calculated width. (The auto converted height function seems to be buggy aswell) However I wish to archive is that it's possible to change the style via jQuery later aswell. So you can change say the max-width attribute and the code will adapt this... Hooking the jQuery css routine later to automatically apply new fixes without a recalc methode is my second goal, but haven't seen yet a good way to do so...
