I've looked all over the Internet for this answer. Here are my attempts, but always return error on the index. Not sure how to check if index not 0.

                DataView dv = new DataView(ds.table1);
                dv.RowFilter = "Name ='" + listbox1.SelectedValue.ToString() + "'";
                dv.Delete(0);
                ds.table1.AcceptChanges();

                - or -
               
                ds.table1.Select("Name ='" + listbox1.SelectedValue.ToString() + "'")[0].Delete();
                ds.table1.AcceptChanges();

sorry i havent tried your code but i will implement the same in a little different way
DataRows rows = ds.table1.Select("Name ='" + listbox1.SelectedValue.ToString() + "'");
for (int i = 0; i < rows.Length; i++
{
     rows[i].Delete();
}
ds.table1.AcceptChanges();

I didn't mention the listbox is bound to a dataset, so that's why I'm having problems. Sorry for the misinformation...

Well, I got it to work although it's messy. I had to use the DataRowView to return the correct ListBox SelectedItem.  Any suggestions are appreciated...
DataRowView drv = (DataRowView)listbox1.SelectedItem;
string item = drv["Name"].ToString();

DataView dv = new DataView(ds.table1);
dv.RowFilter = "Name ='" + Item + "'";
dv.Delete(listbox1.SelectedIndex);
ds.table1.AcceptChanges();
