将 Datagridview 文本框焦点移动到下一个而不是在条形码读取完成时向下移动

Question

我正在使用条码扫描器。在简单的文本框中，我通过查找 Keys.Return 来处理 KeyPress 事件。这帮助我知道条形码读取已经完成。但是在使用 datagridview 文本框时。条形码 reader 不在按键事件上发送 return 默认情况下，datagridview 在条形码读取后将光标向下移动 completion.I 想要将 datagridview 文本框的焦点移动到下一个单元格而不是向下。我该如何处理？我目前的实现如下：

 private void dgvListItems_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
       {
             DataGridViewTextBoxColumn textBox = (DataGridViewTextBoxColumn)dgvMeterData.Columns["MeterId"];
            if (dgvMeterData.CurrentCellAddress.X == textBox.DisplayIndex)
            {
                TextBox tb = e.Control as TextBox;
                if (tb != null)
                {
                    tb.KeyPress += tb_KeyPress;
                }
            }
        }} 



private void tb_KeyPress(object sender, KeyPressEventArgs e)
        {
            TextBox tb = sender as TextBox;
            if (e.KeyChar==(char)Keys.Return)
            {
                tb.Text = tb.Text + e.KeyChar;
                var columnIndex = dgvMeterData.CurrentRow.Cells["TestResults"].ColumnIndex;
                var rowIndex = dgvMeterData.CurrentRow.Cells["TestResults"].RowIndex;
                dgvMeterData.CurrentCell = (DataGridViewCell)dgvMeterData[columnIndex, rowIndex];
            }
        }

这帮助我做了几乎相同的事情。我希望你明白了。

    private void dgvListItems_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        if (e.Control is DataGridViewTextBoxEditingControl)
        {
            DataGridViewTextBoxEditingControl tb = e.Control as DataGridViewTextBoxEditingControl;
            tb.PreviewKeyDown -= dgvListItems_PreviewKeyDown;
            tb.PreviewKeyDown += dgvListItems_PreviewKeyDown;
        }
    }

    private void dgvListItems_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
    {
        if (e.KeyData == Keys.Return)
        {
            int columnIndex = dgvListItems.CurrentCell.ColumnIndex; ;
            int rowIndex = dgvListItems.CurrentCell.RowIndex;

            if (columnIndex == dgvListItems.Columns.Count - 1)
            {
                dgvListItems.CurrentCell = dgvListItems[0, rowIndex + 1];
            }
            else
            {
                dgvListItems.CurrentCell = dgvListItems[columnIndex + 1, rowIndex];
            }
        }
    }
