1) 行右鍵菜單

private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e){if (e.Button == MouseButtons.Right){ if (e.RowIndex >= 0){ //若行已是選中狀態就不再進行設置 if (dataGridView1.Rows[e.RowIndex].Selected == false){ dataGridView1.ClearSelection(); dataGridView1.Rows[e.RowIndex].Selected = true; } //只選中一行時設置活動單元格 if (dataGridView1.SelectedRows.Count == 1){dataGridView1.CurrentCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex]; }if (dataGridView1.CurrentRow != null){int idx = dataGridView1.CurrentRow.Index;if (idx >= 0){string isexport = mDataTableCun.Rows[idx]["ISEXPORT"].ToString();if (isexport == "已導出"){//彈出操作菜單 contextMenuStrip1.Show(MousePosition.X, MousePosition.Y); }}}} } }

2) 行自動編號

private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e){Rectangle rectangle = new Rectangle(e.RowBounds.Location.X,e.RowBounds.Location.Y,dataGridView1.RowHeadersWidth - 4,e.RowBounds.Height);TextRenderer.DrawText(e.Graphics, (e.RowIndex + 1).ToString(),dataGridView1.RowHeadersDefaultCellStyle.Font,rectangle,dataGridView1.RowHeadersDefaultCellStyle.ForeColor,TextFormatFlags.VerticalCenter | TextFormatFlags.Right);}

3) 單元格取值設值

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e){if (e.ColumnIndex == 2){dataGridView1.EndEdit();string ischeck = dataGridView1.Rows[e.RowIndex].Cells["visible"].Value.ToString();if (ischeck == "0"){dataGridView1.Rows[e.RowIndex].Cells["edit"].Value = "0";}}}
