DevExpress學習之GridControl多行復制粘貼

複製是GridControl自帶的屬性，主要解決的是多個單元格複製的問題，這裏涉及到兩個參數

主要是粘貼的

先定義兩個全局變量，在單元格點擊事件的時候獲取單元格的行號和列號

    //獲取當前選中單元格所在的列序號
   int curntindex;
   //獲取獲取當前選中單元格所在的行序號
   int rowindex;
   private void GV_RowCellClick(object sender, RowCellClickEventArgs e)
        {
            //獲取當前選中單元格所在的列序號
            curntindex = e.Column.ColumnHandle;
            //獲取獲取當前選中單元格所在的行序號
            rowindex = e.RowHandle;

            //MessageBox.Show(curntindex.ToString());
            //MessageBox.Show(rowindex.ToString());
        }

然後定義個函數，對剪切板的數據進行格式處理

  private void Paste()
        {
            try
            {
                GridControl x = (GridControl)gridControl1;
                DataTable dt = x.DataSource as DataTable;
                // 獲取剪切板的內容，並按行分割
                string pasteText = Clipboard.GetText();
                MessageBox.Show(pasteText);
                if (string.IsNullOrEmpty(pasteText))
                {
                    MessageBox.Show("剪切板內容爲空，請重新複製！");
                    return;
                }

                int tnum = 0;
                int nnum = 0;
                //獲得當前剪貼板內容的行、列數
                for (int i = 0; i < pasteText.Length; i++)
                {
                    if (pasteText.Substring(i, 1) == "\t")
                    {
                        tnum++;
                    }
                    if (pasteText.Substring(i, 1) == "\n")
                    {
                        nnum++;
                    }
                }
                Object[,] data;
                //粘貼板上的數據來自於EXCEL時，每行末都有\n，在DATAGRIDVIEW內複製時，最後一行末沒有\n
                if (pasteText.Substring(pasteText.Length - 1, 1) == "\n")
                {
                    nnum = nnum - 1;

                }

                tnum = tnum / (nnum + 1);
                data = new object[nnum + 1, tnum + 1];//定義一個二維數組

                String rowstr;
                rowstr = "";
                //MessageBox.Show(pasteText.IndexOf("B").ToString());
                //對數組賦值
                for (int i = 0; i < (nnum + 1); i++)
                {
                    for (int colIndex = 0; colIndex < (tnum + 1); colIndex++)
                    {
                        //一行中的最後一列
                        if (colIndex == tnum && pasteText.IndexOf("\r") != -1)
                        {
                            rowstr = pasteText.Substring(0, pasteText.IndexOf("\r"));
                        }
                        //最後一行的最後一列
                        if (colIndex == tnum && pasteText.IndexOf("\r") == -1)
                        {
                            rowstr = pasteText.Substring(0);
                        }
                        //其他行列
                        if (colIndex != tnum)
                        {
                            rowstr = pasteText.Substring(0, pasteText.IndexOf("\t"));
                            pasteText = pasteText.Substring(pasteText.IndexOf("\t") + 1);
                        }
                        data[i, colIndex] = rowstr;
                    }
                    //截取下一行數據
                    pasteText = pasteText.Substring(pasteText.IndexOf("\n") + 1);

                }



                for (int j = 0; j < (nnum + 1); j++)
                {
                    for (int colIndex = 0; colIndex < (tnum + 1); colIndex++)
                    {
                        this.GV.GetDataRow(j + rowindex)[colIndex + curntindex] = data[j, colIndex];
                        //GV.Rows[j + rowindex].Cells[colIndex + curntindex].Value = data[j, colIndex];
                    }
                }


                //string[] lines = pasteText.Split(new char[] { ' ', ' ' });
                //string s = String.Join("' '", lines);
                //MessageBox.Show(s);
                //foreach (string line in lines)
                //{
                //    if (string.IsNullOrEmpty(line.Trim()))
                //        continue;
                //    // 按 Tab 分割數據
                //    string[] vals = line.Split(' ');
                //    dt.Rows.Add(vals);

            }
            catch
            {
                // 不處理
            }
        }

然後在GridView的KeyDown事件設置粘貼快捷鍵Ctrl+V

 private void Grid_KeyDown(object sender, KeyEventArgs e)
        {
           if ((e.Control == true) && e.KeyCode == Keys.V)
            {
                Paste();
            }
        }
