Setting values in a new datarow

I am using a bound datagrid, and I need to set some values in a new row when the user clicks a button. How do I get the handle (or index) of the new row so I can set the values?

Thanks!

Dim objNewRow as DataRow
objNewRow = objTable.NewRow()

objNewRow("Author") = "William T"
objNewRow("Title") = "Develop Distributed Applications with Notepad"

objTable.Rows.Add(objNewRow)
