Hello Francis,

I have logged this as a development issue.  I have also created a support case and have given you more information there.

Hi Benoit,

No, I don't think these are supported.

However, while testing this out, I noticed that when I enabled Column Swapping, the column headers are displaying the dropdown arrow, but clicking on it does not do anything. So I think there's a bug there. It should either work or not show the arrows.

I'm going to forward this thread over to Infragistics Developer Support so they can create a case for you and have this looked at.
