SqlConnection conn = new SqlConnection(strConn);
conn.Open();
string strSql = "SELECT * FROM CarFee";
SqlDataAdapter sda = new SqlDataAdapter(strSql, conn);
sda.Fill(ds, "ds");
conn.Close();
dataGridView1.DataSource=ds.Tables[0];
}

//dataGridView1事件
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (e.RowIndex >= 0)
{
DataGridViewColumn column = dataGridView1.Columns[e.ColumnIndex];
if (column is DataGridViewButtonColumn)
{
//这里可以编写你需要的任意关庆链脊于按钮事件的操作~
MessageBox.Show("按钮被点击唤耐");
}
}
}
}
}
