This seem like it should be a no-braining, but it escapes me...

Setting a cell/column format to Numeric

iGrid 3.0

I finally found

iGrid1.CellFmtString(i, 1) = "###0"

But it does not work correctly, I get 1,11,111,12,13 etc.....

What result do you expect to see?

And your format string looks strange. See VB format string examples, for instance, here:
