How is it possible?
I have a FlexGrid that has a header on 2 lines. Some cols of the first line needs to be merged togheter. This is done easily by setting .AllowMerging = C1.Win.C1FlexGrid.AllowMergingEnum.FixedOnly
Now, I have added a hierarchy in my grid to display the rows grouped by a column. but this group desciption is very long. So I would like like to set .AllowMerging = C1.Win.C1FlexGrid.AllowMergingEnum.Spill
Any demos of that?
