Question

I need to add some “total rows” to a table. The code I am currently using for the sub totals is:

DataRow shRow = ds.Tables[0].NewRow();
shRow["a"] = "SubHead";
shRow["b"] = "Wheel Subs";
shRow["c"] = totalWheels;

Since I need totals and sub totals and sub sub totals I have to cut and paste this code (changing the values) for each new sub total.

I would like to have a function that takes the current table and values and adds the new row.
Something like:

public DataRow SubRow(DataTable ResultsTable, string SubHead, string SubHeader, string SubHeadValue)

That would then update the table in the main function.

Thanks for any help.
I just can’t ‘pass’ the table to and from the new function.

Whats wrong with that?

public DataRow SubRow(DataTable resultsTable, string subHead, string subHeader, string subHeadValue)
{
    DataRow shRow = resultsTable.NewRow();
    shRow["a"] = subHead;
    shRow["b"] = subHeader;
    shRow["c"] = subHeadValue;
    return shRow;
}

Usage:

DataRow shRow = SubRow(ds.Tables[0], "SubHead", "Wheel Subs", totalWheels);

By the way, this will not add the row to the table, but only create a row that can fit into the table appropriately. If you actually want to ADD the row to the table, you can do:

DataRow row = ds.Tables[0].Rows.Add("SubHead", "Wheel Subs", totalWheels);

That will add a row with the given values to the Add method to the datatable, and return the row that has been added.
