Issue with Grid Panel in IE10

Hi,



We have an application developed on EXT JS which is working in IE8, when we test the same application on IE9 and IE10 we have issues with Grid panel.



It throws run-time error "Object does not support this property or method" at the following line of code.



rolesearchgrid = new Ext.grid.GridPanel({ .....}).



Need your help!



Regards,
