GanttGrid column widths and hiding columns

Question

I am trying to set specific column widths on custom columns I am inserting into the GanttGrid in the GanttControl. The widths do not get respected when the control renders. Also, I want to dynamically be able to show and hide the columns - how would I go about doing that.

Thanks,

Eric
