一.新增：

private void newBtn_Click(object sender, EventArgs e)
        {
                CIL_Currency_Add f7 = new CIL_Currency_Add("新增", "", "");
                    if (f7.ShowDialog() == DialogResult.OK)
                    {
                        if (CIL_Currency_Add.gc.tt == "true" )
                        {
                            gridView1.AddNewRow();
                        }               
                    }
                //重复新增
                while (CIL_Currency_Add.gc.btn == "true")
                {
                    CIL_Currency_Add f8 = new CIL_Currency_Add("新增", "", "");

                    if (f8.ShowDialog() == DialogResult.OK)
                    {
                        if (CIL_Currency_Add.gc.tt == "true" )
                        {
                            gridView1.AddNewRow();
                        }

                    }
                }
            
        }
二.删除

//批量删除

private void ManyDel_Click(object sender, EventArgs e) { if (MessageUtil.ShowYesNoAndTips("确认删除?, 删除的信息无法恢复！！！") == DialogResult.Yes) { //获取选择行的RowHandle， int[] rowHandles = gridView1.GetSelectedRows(); for (int i = 0; i < rowHandles.Length; i++) { Mm.CurrencyCode = this.gridView1.GetRowCellValue(rowHandles[i], "CurrencyCode").ToString(); bool dd = Bb.Delete(Mm.CurrencyCode); } MessageUtil.ConfirmShow("操作成功"); } else { return;//即取消此操作。 } gridView1.DeleteSelectedRows(); }

//行内删除
  private void repositoryItemButtonEdit2_ButtonClick(object sender, DevExpress.XtraEditors.Controls.ButtonPressedEventArgs e)
        {
          
                string CurrencyCode = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "CurrencyCode").ToString();
                Mm.CurrencyCode = CurrencyCode;

                if (MessageUtil.ShowYesNoAndTips("确认删除?, 删除的信息无法恢复！！！") == DialogResult.Yes)
                {
                    bool dd = Bb.Delete(Mm.CurrencyCode);
                    if (dd == true)
                    {
                        MessageUtil.ConfirmShow("操作成功");
                        gridView1.DeleteRow(gridView1.FocusedRowHandle);
                   

                    }
                    else
                    {
                        MessageUtil.ShowTips("操作失败");
                    }
                }
                else
                {
                    return;//即取消此操作。
                }
            
        }
三.修改

//行内修改

private void repositoryItemButtonEdit1_ButtonClick(object sender, DevExpress.XtraEditors.Controls.ButtonPressedEventArgs e) { string CurrencyCode = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "CurrencyCode").ToString(); string Txt = gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "Txt").ToString(); CIL_Currency_Add f7 = new CIL_Currency_Add("修改", CurrencyCode, Txt); if (f7.ShowDialog() == DialogResult.OK) { gridView1.SetRowCellValue(gridView1.FocusedRowHandle, gridView1.Columns["Txt"], CIL_Currency_Add.gc.t2); } }

四。接收传值页面

 public CIL_Currency_Add(string button, string CurrencyCode, string Txt)
         : this()
        {
            Action = button;
            this.Text = Action;
            CurrencyCodeEdit.Text = CurrencyCode;
            TxtEdit.Text = Txt;
        }
