>myDataTable.Rows[rowNumber].Columns[0]

will return value for the first column. (rowNumber is 0 based)

rownumber 1 would be column 1, rownumber 2 would be column 2, rownumber 3 would be column 3, 4 would be 1, 5 would be 2, 6 would be 3, 7 would be 1 etc.
Is there a mathematical function using rownumber that will return the column number?
