>Where do you have the header class defined?

It doesn't really matter, as long as it is defined before the grid is initialized. Just remember that headers cannot be subclassed visually, this is why it must be done in code every time. I would put it in a procedure file or the startup program of the app.

To make it more widely usable, my grid class actually has properties where you can specify what class to use for the different data types, and for the header:

ccolumn.AddObject("myheader1", thisform.headerclass),
ccolumn.AddObject("myheader1",thisform.logicalclass)

This is in case you have defined more than one class for the header and you want to use different headers on different forms.
