This is how I am freezing and unfreezing the columns. I also tried to attach an image of my issue, but I am not sure it attached properly.
GridColumn column = columns.SingleOrDefault(x => x.DataField.Equals(columnName));
column.ColumnGroup = “Frozen”;
column.Freeze = “near”;
GridColumn column = columns.SingleOrDefault(x => x.DataField.Equals(frozenColumn));
column.ColumnGroup = fieldToGroup[frozenColumn];
column.Freeze = “false”;
