The issue I found is only with date columns, if we make allowFiltering: false on date columns on grid then Grid renders fine else Grid shows issue in rendering.

weird issue, could someone please suggest why this is happening

Added those files but still getting following error

infragistics.excel.js:88 Uncaught TypeError: $$t.$fw.getBox is not a function

Got further with it…now new errors..

infragistics.excel.js:88 Uncaught TypeError: $$t.$fw.getBox is not a function
infragistics.excel.js:30 Uncaught TypeError: $$t.$cg.c is not a function

We are loading infragistics.core.js, infragistics.dv.js, and infragistics.lob.js in same order

I changed the order to be infragistics.loader.js, infragistics.core.js, infragistics.dv.js, and infragistics.lob.js, infragistics.document.core.js, infragistics.gridexcelexporter.js

Is this order correct? All files required? 

I am now getting an error Uncaught TypeError: Cannot read property 'Workbook' of undefined
