There has been some problem on my Radgrid viewing it on IE11/Windows 8.1. Columns not expanding, text are not showing and the whole grid is squeezing. Its working fine with Chrome and Firefox ver 26 and 27 running on Windows 8.1. Any info why this happening?
Can you try upgrading to the latest version of Telerik. The misalignments and issues of RadGrid rendering in IE 11 were fixed in the latest version. Take a look at this article on Release History of Q3 2013 SP1 (version 2013.3.1114).
Hope this helps.
