datagridview columns

[DaveL]

Hi
Im building a windows form with a datagridview control on it

I want to size my columns based on the datatable
I Recieve a String separated by columNames, to be placed in the grid view
in my method to size the columns,
I get the table, match the columns but i can't find
a property for the size, precision, scale, etc of the column

Thanks
DaveL
