Setting Filters on Infragistsics Ultragrid

Hi,

I am trying to set a Column Filter in Infragistics Ultragrid object. I am not able to find any method or object that I can access to achieve this. The area where the filter is located (between header and firstrow) doesn't show up in Object Spy (it ony shows when I click on it but that comes as a general text editor without any column data).

Kindly let me know if anyone has achieved filtering on Infragistics Ultragrid and how they achieved it.

Thanks,

Yusuf
