Thanks Doug! I'm gonna give them a good read because the data works
but the column seems to be not a child of the datagrid any longer.. I
can resize the column header but the data stays in the same place, if
I shrink the page the data bunches up with other columns so it's not
exactly right.
Anywho, off to read Peter's blog, should give me a good know-how for this
