I'm sure this is probably a CSS issue, but not sure where to look. I have a Grid inside a PanelBar with grouping and the X of the grouping buttons is overlapping the grid header row. See attached image.
.Groupable(grouping => grouping .Groups(groups=> { groups.Add(c => c.Substn); groups.Add(c => c.Devtyp); groups.Add(c => c.Device); groups.Add(c => c.Analog); }) )
