我有一个带有只读数据网格视图的表单。当用户在数据网格视图线上下移动光标时，我想显示一个与突出显示的线相关的图形。我尝试使用 DataGridView1_SelectionChanged事件，但它从未被执行。
dataGridView1_CellContentClick_1做的伎俩，但要求用户点击我想避免的。
public partial class conf_results : Form
{
private DataSet ds = new DataSet();
private DataTable dt = new DataTable();
private NpgsqlDataAdapter da = new NpgsqlDataAdapter();
private NpgsqlCommandBuilder sBuilder = new NpgsqlCommandBuilder();
public conf_results()
{
InitializeComponent();
try
{
// PostgeSQL-style connection string
// Making connection with Npgsql provider
NpgsqlConnection conn;
conn = new NpgsqlConnection(Properties.Settings.Default.connString);
conn.Open();
string sql = "SELECT m.orig_code,m.sejtvonal,round_dbl(m.parm_b,2),round_dbl(m.parm_c,2),round_dbl(m.variance,2),round_dbl(100 /(2^(m.ic50 - 1)),2),m.toxic,m.meres_id, " +
"d.sejtvonal,round_dbl(d.parm_b,2),round_dbl(d.parm_c,2),round_dbl(d.variance,2),round_dbl(100 /(2^(d.ic50 - 1)),2),d.toxic,d.meres_id " +

"and m.sejtvonal='Mes-Sa' and d.sejtvonal='Dx5'";
da = new NpgsqlDataAdapter(sql, conn);
sBuilder = new NpgsqlCommandBuilder(da);
DataSet ds = new DataSet();
// filling DataSet with result from NpgsqlDataAdapter
//da.Fill(ds);
da.Fill(ds, "vegyulet_curve");
// since it C# DataSet can handle multiple tables, we will select first
dt = ds.Tables["vegyulet_curve"];
// connect grid to DataTable
dataGridView1.DataSource = ds.Tables["vegyulet_curve"];
conn.Close();

// something went wrong, and you wanna know why
MessageBox.Show(msg.ToString());
throw;
