Question

我有一个带有列的DGV，我希望用另一个数据库填充信息，我只想读取ID并将与该ID相关联的名称写入列。所以，我写了这个：

string constring5 = @"Data Source=antonio;Initial Catalog=JurisFrameWorkSPROC;User ID=;Password=";
string Query5 = "select Nome from Advogado where IDAdvogado= '" + dataGridView1.CurrentRow.Cells[6].Value + "'";
SqlConnection cn5 = new SqlConnection(constring5); /*Ligação à base de dados*/
SqlCommand cmd5 = new SqlCommand(Query5, cn5); /*Declaracao para usar comandos SQL*/
try
{
    cn5.Open();
    using (SqlDataReader read5 = cmd5.ExecuteReader())
    {
          while (read5.Read())
          {
            dataGridView1.CurrentRow.Cells[7].Value = (read5["Nome"].ToString());

          }
     }
}
finally
{
     cn5.Close();
}

并且它有效，但仅适用于第1行，但我希望它适用于所有行！行[e.RowIndex]在这里不起作用，因为发件人。

Anyony可以帮帮我吗？大家都是

我已经这样做了

  for (int i = 0; i < dataGridView1.Rows.Count; i++)
            {
                string constring5 = @"Data Source=antonio;Initial Catalog=JurisFrameWorkSPROC;User ID=sa;Password=1236540nine";
                string Query5 = "select Nome from Advogado where IDAdvogado= '" + dataGridView1.Rows[i].Cells[6].Value + "'";
                SqlConnection cn5 = new SqlConnection(constring5); /*Ligação à base de dados*/
                SqlCommand cmd5 = new SqlCommand(Query5, cn5); /*Declaracao para usar comandos SQL*/

                try
                {
                    cn5.Open();
                    {

                        using (SqlDataReader read5 = cmd5.ExecuteReader())
                        {

                            while (read5.Read())
                            {
                                //dataGridView1.CurrentRow.Cells[7].Value = (read5["Nome"]);
                                dataGridView1.Rows[i].Cells[7].Value = (read5["Nome"]);

                            }
                        }
                    }
                }
                finally
                {
                    cn5.Close();
                }
            }
        }

但是，如果我进行某种搜索，此代码到达的所有填充列都会消失：\
