Question

我创建了一个表单，其中有4个标签教师ID，教师姓名，部门和说明以及相应的文本框。我已经通过ADD按钮（使用插入查询）在数据库中插入了值。我已经采用数据网格视图来显示数据。

问题是现在我想要当iIselect一行datagridview然后它应该在各自的文本框中显示u =其数据。我尝试过以下代码，但无法正确编写代码。

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{

SqlConnection con = new SqlConnection("Data Source=SW-PC-20;Integrated security =SSPI;Initial catalog=institute");

con.Open();
SqlCommand com = new SqlCommand("select * from teacher2", con);
SqlDataReader dr = com.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(dr);
dr.Close();
dataGridView1.DataSource = dt;
     if (dr.HasRows)
                dr.Read();
         txtteacherid.Text = dr[0].ToString();
         txtteachername.Text = dr[1].ToString();
         txtdepartment.Text = dr[2].ToString();
         txtdescription.Text = dr[3].ToString();
}

   private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {

     if (e.RowIndex > -1)
                {
                    txtteacherid.Text = dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();
                    txtteachername.Text = dataGridView1.Rows[e.RowIndex].Cells[1].Value.ToString();
                    txtdepartment.Text = dataGridView1.Rows[e.RowIndex].Cells[2].Value.ToString();
                    txtdescription.Text = dataGridView1.Rows[e.RowIndex].Cells[3].Value.ToString();
                }

    }
