using windows application.
first form details: two datagrids--first for main table, second for sub table (they are related in dataset)
how do I sum the column containing rows of numbers into a single row of total amount in the "sub table" datagrid ?
second form: same as above.
how do I set up the date difference--"sub table" datagrid with three columns (col 1 - previous date, col 2 - current date, col 3 - date difference by DAYS)
the data comes from a xml file and is stored in the dataset. I don't know if i need to do something with xml schema...
hope these details help...thanks
