c# - 当前单元格不能设置为datagridview中的不可见单元格

Question

我在 datagridview 中遇到了问题。 I have done some code in keydown event for changing the tab focus but when tab reaches last of column it gives a error

"Current cell cannot be set to an invisible cell".

我让最后一个单元格不可见，因为我不想让那个单元格可见。

我在KeyDown事件中写了下面的代码

private void m3dgvDepositDetails_KeyDown(object sender, KeyEventArgs e)
{
  try
  {
    if (e.KeyCode == Keys.Tab && notlastColumn)
    {
      e.SuppressKeyPress = true;
      int iColumn = m3dgvDepositDetails.CurrentCell.ColumnIndex;
      int iRow = m3dgvDepositDetails.CurrentCell.RowIndex;
      if (iColumn == m3dgvDepositDetails.Columns.Count - 1)
        m3dgvDepositDetails.CurrentCell = m3dgvDepositDetails[0, iRow + 1];
      else
        m3dgvDepositDetails.CurrentCell = m3dgvDepositDetails[iColumn + 1, iRow];
    }
  }
  catch (Exception ex)
  {
    CusException cex = new CusException(ex);
    cex.Show(MessageBoxIcon.Error);
  }
}

错误是不言自明的:您将 CurrentCell 设置为不可见的单元格并且它是被禁止的，这意味着单元格的行 或 单元格的列是隐。为避免这种情况，请不要在设置 CurrentCell 之前隐藏行/列或检查 Visible 属性。

如果问题是您应该使用的最后一列:

private void m3dgvDepositDetails_KeyDown(object sender, KeyEventArgs e)
    {
        try
        {
            if (e.KeyCode == Keys.Tab && notlastColumn)
            {
                e.SuppressKeyPress = true;
                int iColumn = m3dgvDepositDetails.CurrentCell.ColumnIndex;
                int iRow = m3dgvDepositDetails.CurrentCell.RowIndex;
                if (iColumn >= m3dgvDepositDetails.Columns.Count - 2)
                    m3dgvDepositDetails.CurrentCell = m3dgvDepositDetails[0, iRow + 1];
                else
                    m3dgvDepositDetails.CurrentCell = m3dgvDepositDetails[iColumn + 1, iRow];

            }
        }
        catch (Exception ex)
        {
            CusException cex = new CusException(ex);
            cex.Show(MessageBoxIcon.Error);
        }
    }
