'WebForm_DoPostBackWithOptions' is undefined in IE11 Preview

Question

IE11 is coming. I just installed the developer preview version. However, if I run some of my web application and I got the error WebForm_DoPostBackWithOptions

Answer 1

Found a temporary fix to this.

I tried applying the hotfix but I couldn't get the hotfix to install. The error was: kb2600088 does not apply, or is blocked by another condition on your computer. Probably due to .NET 4.5, I googled abit but I didn't want to uninstall .NET 4.5 so I didn't follow through.

So, to get around the original problem, start IE11 and go to developer's console by pressing F12. Under 'Emulation' tab, set document mode to '10' and under user agent string, set it to '10' as well. I believe it emulates IE 10 which works perfectly fine without having to run into this bug.

This is only a work around. Not a fix. Hope it helps those trying to get work done.
