按Enter键时，如何将dataGridView光标转到下一行

我已经编写了下面的代码“当用户按下进入时转到下一个单元格”，但代码不起作用，我无法找到错误。

private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == Keys.Enter) { int col = dataGridView1.CurrentCell.ColumnIndex; int row = dataGridView1.CurrentCell.RowIndex; if (col < dataGridView1.ColumnCount - 1) { col++; } else { col = 1; row++; } if (row == dataGridView1.RowCount) { dataGridView1.Rows.Add(); dataGridView1.CurrentCell = dataGridView1[col, row]; e.Handled = true; } } }

在过去，我发现实现这种行为的最佳方法是创建一个inheritance自DataGridView并覆盖ProcessCmdKey函数的自定义控件。

 public class MyDataGridViewControl : DataGridView { protected override Boolean ProcessCmdKey(ref Message msg, Keys keyData) { Boolean handled = false; if ((keyData == Keys.Enter || keyData == Keys.Return)) { handled = NavigateToNextCell(); } if (!handled) { handled = base.ProcessCmdKey(ref msg, keyData); } return handled; } private Boolean NavigateToNextCell() { Boolean retVal = false; if (CurrentCell != null) { Int32 columnIndex = CurrentCell.ColumnIndex; Int32 rowIndex = CurrentCell.RowIndex; DataGridViewCell targetCell = null; do { if (columnIndex >= Columns.Count - 1) { // Move to the start of the next row columnIndex = 0; rowIndex = rowIndex + 1; } else { // Move to the next cell on the right columnIndex = columnIndex + 1; } if (rowIndex >= RowCount) { break; } else { targetCell = this[columnIndex, rowIndex]; } } while (targetCell.Visible == false); if (targetCell != null) { CurrentCell = targetCell; } retVal = true; } return retVal; } }

我已经解决了这个问题。 现在它的工作正常…..

 private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == Keys.Enter) { int row = dataGridView1.CurrentCell.RowIndex; int colIndex = dataGridView1.CurrentCell.ColumnIndex; if (colIndex < dataGridView1.Columns.Count - 1) { dataGridView1.CurrentCell = dataGridView1.Rows[row].Cells[colIndex + 1]; dataGridView1.Focus(); } else if (colIndex == dataGridView1.Columns.Count - 1) { dataGridView1.Rows.Add(1); dataGridView1.CurrentCell = dataGridView1.Rows[row].Cells[0]; dataGridView1.Focus(); } }
