Well, when using any grid there are always certain things that need to be taken into account.  However, if you are using a BBS (BusinessBindingSource) then you should be in good shape.  There is a sample that comes with SF (you will have to update the references if you are using the "beta") that shows how to use a BO with a standard DataGridView which will work the same on an Infragistics grid as well.  We use an Infragistics grid in our applications and it will work fine.  We also have a large number of SF users that use both Infragistics and DevExpress grids as well, so this is a tried practice.  If you could provide the exception and stack trace with your error that would help also.  Thanks.

Dear All,

      I want to apply the Infragistics ultrgrid to my application, but more difficult to control it. My Form with the master and detail table. the ultragrid bind the detail data in it. when i click the undo button the grid will have a error occur . So, Do you have any idea to control the ultragrid? or upload a sample with master & detail table and the maintenance toolstrip.

Regards,
