Here is a trick with what you want to achieve. I was also having problem like you.

Its hard to get selected row and data key in RowDeleting Event But it is very easy to get selected row and datakeys in SelectedIndexChanged event. Here's an example-

protected void gv_SelectedIndexChanged(object sender, EventArgs e)
{
        int index = gv.SelectedIndex;
        int vehicleId = Convert.ToInt32(gv.DataKeys[index].Value);
        SqlConnection con = new SqlConnection("-----");
        SqlCommand com = new SqlCommand("DELETE FROM tbl WHERE vId = @vId", con);
        com.Parameters.AddWithValue("@vId", vehicleId);
        con.Open();
        com.ExecuteNonQuery();
}
