winForm datagridview 操作小方法

datagridview 粘贴功能(以下)

 private  void DataGirdViewCellPaste(DataGridView grid)

        {

            try

            {

                // 获取剪切板的内容，并按行分割

                string pasteText = Clipboard.GetText().Trim();

                if (string.IsNullOrEmpty(pasteText))

                    return;

                string[] lines = pasteText.Replace("\r\n","|").Replace("\t","^").Split('|');

                int currRow = grid.CurrentCell.RowIndex;

                if ((grid.Rows.Count-currRow)<lines.Length)

                {

                    MessageBox.Show("粘贴的行数越界！", "提示！");

                    return;

                }

            

                int rowNum = 0;

                int colNum = 0;

                int currCol = grid.CurrentCell.ColumnIndex;

                for (int i = currRow; i < currRow+lines.Length; i++)

                {

                    colNum = 0;

                    string[] vals = lines[rowNum].Split('^');

                    rowNum++;

                    if (vals.Length>(grid.Columns.Count-currCol))

                    {

                        MessageBox.Show("粘贴的列数越界！", "提示！");

                        return;

                      

                    }

                    for (int k= 0; k < vals.Length; k++)

                    {

                        if (!Common.IsDecimalNoEmptyNull(ref vals[k]))

                        {

                            MessageBox.Show("粘贴的数据中含有非数字字符！", "提示！");

                            return;

                        }

                    }

                    for (int j = currCol; j < currCol+vals.Length; j++)

                    {

                        grid.Rows[i].Cells[grid.Columns[j].HeaderText].Value = vals[colNum];                    

                        colNum++;

                    }

              

                }

                 

            }

            catch

            {

                // 不处理

            }

        }

//Ctrl+V 调用上面的方法

 private void dataGridView2_KeyDown(object sender, KeyEventArgs e)

        {

            if (Control.ModifierKeys == Keys.Control && e.KeyCode == Keys.V)

            {

                if (sender != null && sender.GetType() == typeof(DataGridView))

                    // 调用上面的粘贴代码

                    DataGirdViewCellPaste(this.dataGridView2);

            }

        }

datagridview中ComboBoxColumn赋值（以下）

 ((DataGridViewComboBoxColumn)this.dataGridView1.Columns["absenceType"]).Items.Add("");

            for (num = 0; num < defaultView.Count; num++)

            {

                ((DataGridViewComboBoxColumn)this.dataGridView1.Columns["absenceType"]).Items.Add(defaultView[num][0]);

            }

datagridview中ComboBoxColumn赋值（以上）

//datagridview中的checkbox改成红勾

((DataGridViewCheckBoxCell)this.dataGridView1.Rows[i].Cells["second"]).Style.ForeColor = Color.Red;

 ((DataGridViewCheckBoxCell)this.dataGridView1.Rows[i].Cells["second"]).FlatStyle = FlatStyle.Popup;
