User · Answer

one more if you want to switch IE 8 page render in IE 8 standard mode   lt meta http-equiv  X-UA-Compatible  content  IE 100    gt   lt  -- IE8 mode -- gt

its even simpler than that  Using HTML you can just add this metatag to your page  first thing on the page     lt meta http-equiv  X-UA-Compatible  content  IE 7    gt    If you wanted to do it using net  you just have to send your http request with that meta information in the header   This would require a page refresh to work though   Also  you can look at a similar question here  Compatibility Mode in IE8 using VBScript

A note to this   IE 8 0s emulation only promises to display the page the same  There are subtle differences that might cause functionality to break  I recently had a problem with just that  Where IE 7 0 uses a javascript wrapper-function called  anonymous    in IE 8 0 the wrapper was named differently   So do not expect things like JavaScript to  just work   because you turn on emulation

This can be done in IIS  http   weblogs asp net joelvarty archive 2009 03 23 force-ie7-compatibility-mode-in-ie8-with-iis-settings aspx  Read the comments as well  Wednesday  April 01  2009 8 57 AM by John Moore  A quick follow-up   This worked great for my site as long as I use the IE EmulateIE7 value   Trying to use the IE 7 resulted in my site essentially hanging when run on IE8

If you add this to your meta tags    lt meta http-equiv  X-UA-Compatible  content  IE EmulateIE7    gt    IE8 will render the page like IE7
