       FRM_Car_Data_List frm = new FRM_Car_Data_List();
       frm.ShowDialog();
       this.txt_Car_id.Text = frm.dataGridView1.CurrentRow.Cells[0].Value.ToString();
       this.txt_Car_No.Text = frm.dataGridView1.CurrentRow.Cells[1].Value.ToString();
       this.txt_Car_No_2.Text = frm.dataGridView1.CurrentRow.Cells[2].Value.ToString();
       this.txt_Car_shs.Text = frm.dataGridView1.CurrentRow.Cells[3].Value.ToString();
       this.txt_Mator_No.Text = frm.dataGridView1.CurrentRow.Cells[4].Value.ToString();
       this.CB_Car_Type.Text = frm.dataGridView1.CurrentRow.Cells[5].Value.ToString();
       this.CB_ModelCar.Text = frm.dataGridView1.CurrentRow.Cells[6].Value.ToString();
       this.txt_year.Text = frm.dataGridView1.CurrentRow.Cells[7].Value.ToString();
       this.txt_Capecity.Text = frm.dataGridView1.CurrentRow.Cells[8].Value.ToString();
       this.txt_Ton.Text = frm.dataGridView1.CurrentRow.Cells[9].Value.ToString();
       this.CB_Color.Text = frm.dataGridView1.CurrentRow.Cells[10].Value.ToString();
       this.dtp_Date_Bay.Text = frm.dataGridView1.CurrentRow.Cells[11].Value.ToString();
       this.dtp_Date_in.Text = frm.dataGridView1.CurrentRow.Cells[12].Value.ToString();
       this.CB_Owner.SelectedItem = frm.dataGridView1.CurrentRow.Cells[13].Value.ToString();
       this.CB_Place.SelectedItem = frm.dataGridView1.CurrentRow.Cells[14].Value.ToString();
       this.dtp_Car_e_date_licen.Text = frm.dataGridView1.CurrentRow.Cells[15].Value.ToString();
       this.txt_Notes.Text = frm.dataGridView1.CurrentRow.Cells[15].Value.ToString();
       this.txt_Car_id.ReadOnly = true;
       this.txt_Car_No.ReadOnly = true;
       this.txt_Car_No_2.ReadOnly = true;
       this.State = "Show";
       this.txt_Car_id.Focus();
       this.btn_Add.Enabled = false;
       this.btn_Edit.Enabled = true;
       this.btn_Delete.Enabled = true;
       this.btn_NewData.Enabled = true;
   }
   catch
   {
       return;
   }
}

第二种形式是： -

second form is :-

public partial class FRM_Car_Data_List : Form
{
  BL.CLS_CARS_DATA frmCls = new BL.CLS_CARS_DATA();

  public FRM_Car_Data_List()
  {
      InitializeComponent();
      this.dataGridView1.DataSource = frmCls.GET_ALL_CARS_DATA();
  }

  private void dataGridView1_DoubleClick(object sender, EventArgs e)
  {
      this.Close();
  }

  private void txt_Search_Car_Data_TextChanged(object sender, EventArgs e)
  {
      DataTable dt = new DataTable();
      dt = frmCls.Search_Car_Data(txt_Search_Car_Data.Text);
      this.dataGridView1.DataSource = dt;
  }
}

推荐答案

我不能把gotether一个测试应用程序，但我会看当您关闭表单时，CurrentRow会发生什么。如果DGV不再可见，查看CurrentRow是否回到第一行。

I can't put gotether a test app, but I'd be looking at what happens to "CurrentRow" when you close the form. See if the "CurrentRow" goes back to the first row if the DGV is no longer visible.
