namespace ArsCRM 
{ 
public partial class Form1 : Form 
{ 

    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
     SqlConnection con = new SqlConnection(); 
     con.ConnectionString = @"Data Source=test\s08r2;Initial Catalog=Demo;User id=sa;Password=123456"; 
     con.Open(); 
     SqlDataAdapter sda = new SqlDataAdapter(@" 
      SELECT acSubject, acAddress, acPost, acName, acPhone, 
      acFieldSA, acFieldSB, acFieldSC, acFieldSD, acFieldSE, 
      anFieldNA, anFieldNB, anFieldNC, anFieldND, anFieldNE, OdgovornaOsoba, acSubjTypeBuyer 
      FROM ARS.dbo._ARSCRM_vSubjekti order by acSubject 
      ", con); 
     DataTable dt = new DataTable(); 
     sda.Fill(dt); 
     dataGridView1.DataSource = dt; 


     } 


    private void txtSearch_TextChanged(object sender, EventArgs e) 
    { 
     if (string.IsNullOrEmpty(txtSearch.Text)) 
     { 
      (dataGridView1.DataSource as DataTable).DefaultView.RowFilter = string.Empty; 
     } 
     else 
     { 
      (dataGridView1.DataSource as DataTable).DefaultView.RowFilter = string.Format("acSubject like '%{0}%'", txtSearch.Text); 
     } 
    } 

    private void dataGridView1_SelectionChanged(object sender, EventArgs e) 
    { 


     DataGridView dgv = (DataGridView)sender; 

     if (dgv.SelectedCells.Count > 0) 
      txtAcFieldSA.Text = dgv.Rows[dgv.SelectedCells[0].RowIndex].Cells[5].Value.ToString();    
    } 

} 
} 

我有這個代碼，它在最後兩行填滿txtAcFieldSA與選定的行6.列。

我想在ComboBox1一些事情。當我選擇ComboBox1填充6.列中的某一行時。那可能嗎？

過不去做根據文本框

private void dataGridView1_SelectionChanged(object sender, EventArgs e) 
      { 


       DataGridView dgv = (DataGridView)sender; 

       if (dgv.SelectedCells.Count > 0) 
       { 
        txtAcFieldSA.Text = dgv.Rows[dgv.SelectedCells[0].RowIndex].Cells[5].Value.ToString(); 
        ComboBox1.Text = dgv.Rows[dgv.SelectedCells[0].RowIndex].Cells[6].Value.ToString(); 
       } 
      } 

，或者如果你想將其作爲項目添加到ComboBox：

private void dataGridView1_SelectionChanged(object sender, EventArgs e) 
     { 


      DataGridView dgv = (DataGridView)sender; 

      if (dgv.SelectedCells.Count > 0) 
      { 
       txtAcFieldSA.Text = dgv.Rows[dgv.SelectedCells[0].RowIndex].Cells[5].Value.ToString(); 

       ComboBox1.Items.Add(dgv.Rows[dgv.SelectedCells[0].RowIndex].Cells[6].Value.ToString();) 
      } 
     }
