Hello to all expert out there, need some help and some solution for the windows IE9, IE8 and IE7 compatibility view mode in following enviroment--> windows 7 (32-bit & 64-bit), Windows Vista. The problem that i faced was that, as i plug in the 'telerik:RadTabStrip' on asp.net page at server side, once client side checked the compatibility view, the telerik tab was missing is there any solution for this? i mean i cant control the clients side either their PC had checked the compatibility view mode.
