Woops... left out the code
FOR lnCount = 1 to this.ColumnCount
ccolumn = this.Columns[lnCount]
ccolumn.RemoveObject("header1")
ccolumn.AddObject("myheader1","myheader")
do case
case type(ccolumn.controlsource) = "N"
ccolumn.RemoveObject("text1")
ccolumn.AddObject("myspinner1","myspinner")
ccolumn.myspinner1.visible = .T.
case type(ccolumn.controlsource) = "L"
ccolumn.RemoveObject("text1")
ccolumn.AddObject("mycheck1","mycheck")
ccolumn.mycheck1.visible = .T.
otherwise
cColumn.RemoveObject("text1")
ccolumn.AddObject("mytext1","Mytext")
ccolumn.mytext1.visible = .T.
endcase
ENDFOR

Of course you must have already created a header class with something like the following:

DEFINE CLASS MyHeader AS Header
PROCEDURE click
blah, blah, blah
ENDPROC
ENDDEFINE

You probably have something like this already laid out, but I thought I'd offer my solution to see if it gave any ideas. It might seem like jumping through hoops to get a simple outcome, but this class can be dropped on a form and VFP takes care of column sizing and controlsources for you. HTH
