You can try setting a style on just that header.

For example,

to keep the space

e.Layout.Bands[0].Columns[0].Header.Style.CustomRules =

"visibility:hidden";

or

to not take up space

e.Layout.Bands[0].Columns[0].Header.Style.CustomRules = "

display:none";

on the same subject, i have a question, i have a grid with two levels of header (0 and 1)

how can i hide level 1 header alone, just the header not the actual column or row values.

Thanks, just found that! 

 Sure.

What if you want the header to be shown in certain bands?  Does this work?
