输入键作为选项卡在 datagridview 中无法正常工作

问：

我创建了一个自定义 DataGridView，并在按 Enter 键时尝试将我的单元格向右移动（而不是在按 Enter 键时向下移动），但我发现我必须按两次 Enter 才能向右移动。当我第一次按回车键时，它仍然向下（默认方式），然后如果我再次按回车键，它就会向右移动。

public partial class Paymentdatagridview : DataGridView
{
    public Paymentdatagridview()
    {
        // i have set enableheadervisualstyles to false 
        // make bold the headers
        // Add the columns to your custom DataGridView
        DataGridViewColumn column1 = new DataGridViewTextBoxColumn();
        column1.Name = "Column1";
        column1.HeaderText = "Particulars";
        column1.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
        column1.SortMode = DataGridViewColumnSortMode.Automatic;
        this.Columns.Add(column1);

        DataGridViewColumn column2 = new DataGridViewTextBoxColumn();
        column2.Name = "Column2";
        column2.HeaderText = "Amount";
        column2.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
        column2.SortMode = DataGridViewColumnSortMode.Programmatic;
        this.Columns.Add(column2);

        this.AllowUserToAddRows = true;
        this.RowHeadersVisible = false;
        this.ColumnHeadersDefaultCellStyle.Font = new Font("Tahoma", 9.75F, FontStyle.Bold);
        this.CellBorderStyle = DataGridViewCellBorderStyle.None;          
        InitializeComponent();
    }

    protected override void OnEnter(EventArgs e)
    {
        // Set the current cell to the first cell and enable editing when the control receives focus
        if (RowCount > 0 && ColumnCount > 0)
        {
            CurrentCell = Rows[0].Cells[0];
            BeginEdit(true);
        }

        base.OnEnter(e);
    }

    protected override bool ProcessDataGridViewKey(KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            // Move the focus to the next column and row when Enter key is pressed
            if (CurrentCell.ColumnIndex == ColumnCount - 1)
            {
                if (CurrentCell.RowIndex == RowCount - 1)
                {
                    // Reached the last cell, move focus to the first cell
                    CurrentCell = Rows[0].Cells[0];
                }
                else
                {
                    // Move to the first cell of the next row
                    CurrentCell = Rows[CurrentCell.RowIndex + 1].Cells[0];
                }
            }
            else
            {
                // Move to the next column
                CurrentCell = Rows[CurrentCell.RowIndex].Cells[CurrentCell.ColumnIndex + 1];
            }

            BeginEdit(true);
            e.Handled = true;
            return true;
        }

        return base.ProcessDataGridViewKey(e);
    }
