>Hi Elyse,

>>I created my own header class in a PRG. In the Init of my grid class, I would like to replace the VFP headers with my header class. This is my code in the Grid.Init():

>>FOR EACH loColumn IN This.Columns
>> loColumn.RemoveObject("Header1")
>> loColumn.AddObject("Header1","MyHeaderClass")
>>ENDFOR
>>
>>I'm getting an error on the AddObject line-"Object name is invalid." If I use a different name, i.e. "HeaderA", it works. Why is this and how can I get around it? I really want to name the headers "Header1" because there are pieces of code that depend on the headers being named as such.

>I don't know WHY the error occurs, but I got it too. So, what I did was the following:

>FOR EACH loColumn IN This.Columns
>     loColumn.RemoveObject("Header1")
>     loColumn.AddObject("Hdr1","MyHeaderClass")
>     loColumn.Hdr1.Name = "Header1"
>ENDFOR

>All is well!

What version are you using?
I tried this and the original code worked just fine for me - I couldn't make it give me any kind of error.
