Team,

I tried many different samples and my local sample for the Grid multi-column sort but it seems like I can't get it work.  I already checked on the AllowSorting, Multi Column Sorting and Show Indicator checkboxes.  But still no luck.  Below is the URL i am trying but not working as well.

Attached the screen captures I had, the first image shows the sorting on Company column and it works.  So far so good. 

But after that when I click on Contact Name column.  It lost the Company sort and only make the Contact Name sorted (single column sort).  I even tried to hold down control key and do the Contact Name click.  Contact Name doesn't do the second sort. 

Please help and advise what the proper way to perform the multi-column sort should be.  Greatly appreciate it.
