Just one thing I found out today: I have a grid where column names aren't Column1, Column2 etc, but rather colItemno, colDescr and such. Then I added a column to it. After saving, it wouldn't allow me to edit it again, nor would it run.

I restored the classlib (the grid is one of six grids on two pages of a pageframe), and tried again, no luck. Then I ran one of my builders which created the code to build the grid from scratch - and started editing that code, just to add a new column where I want it, adjust the widths etc.

It started erroring out on oGrd.AddObject("colSomething","column"), under a funny error "cannot change recordsource of a browse object". After several tries, I just gave up on my custom names, and went with

oGrd.addcolumn()
with oGrd.columns[this.columncount]

and kept the rest of the code as it was. And it worked.

So, while my problem is solved (and I'll probably adjust the builder to do it like this from now on), I'd like to know whether anyone else had problems with grids with custom-named columns.
