如何在Enter键按下事件的数据视图中将焦点移动到下一个单元格

Question

朋友们,我正在使用C#处理Windows应用程序.我正在使用datagridview来显示记录.我需要的功能是当我按下"Enter"键时,焦点应该转到下一个单元格(同一行的列).如果它是网格中的最后一列,那么焦点应该转到下一行的第一列.我已经尝试过了

    SendKeys.Send("{Tab}")

在datagridview1_KeyDown和datagridview1_KeyPress事件中.但重点是对角线向下移动.请帮我解决这个问题.

Answer 1

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
{
    e.SuppressKeyPress = true;
    int iColumn = dataGridView1.CurrentCell.ColumnIndex;
    int iRow = dataGridView1.CurrentCell.RowIndex;
    if (iColumn == dataGridView1.Columncount-1)
    {
        if (dataGridView1.RowCount > (iRow + 1))
        {
            dataGridView1.CurrentCell = dataGridView1[1, iRow + 1];
        }
        else
        {
            //focus next control
        }
    }
    else
        dataGridView1.CurrentCell = dataGridView1[iColumn + 1, iRow];
}

Answer 2

protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, System.Windows.Forms.Keys keyData)
{
    int icolumn = dataGridView1.CurrentCell.ColumnIndex;
    int irow = dataGridView1.CurrentCell.RowIndex;

    if (keyData == Keys.Enter)
    {                                
        if (icolumn == dataGridView1.Columns.Count - 1)
        {
            dataGridView1.Rows.Add();
            dataGridView1.CurrentCell = dataGridView1[0, irow + 1];
        }
        else
        {
            dataGridView1.CurrentCell = dataGridView1[icolumn + 1, irow];
        }
        return true;
    }
    else
        return base.ProcessCmdKey(ref msg, keyData);
    }
}

您可以使用datagridview的selectionchanged事件.在你的形式

       private DataGridViewCell _celWasEndEdit;

        private void datagridview_SelectionChanged(object sender, EventArgs e)
    {

        if (MouseButtons != 0) return;

        if (_celWasEndEdit != null && datagridview.CurrentCell != null)
        {
            // if we are currently in the next line of last edit cell
            if (datagridview.CurrentCell.RowIndex == _celWasEndEdit.RowIndex + 1 &&
                datagridview.CurrentCell.ColumnIndex == _celWasEndEdit.ColumnIndex)
            {
                int iColNew;
                int iRowNew = 0;
                if (_celWasEndEdit.ColumnIndex >= datagridview.ColumnCount - 1)
                {
                    iColNew = 0;
                    iRowNew = dgvItems.CurrentCell.RowIndex;                   
                }
                else
                {
                        iColNew = _celWasEndEdit.ColumnIndex + 1;
                        iRowNew = _celWasEndEdit.RowIndex;
                }
                datagridview.CurrentCell = datagridview[iColNew, iRowNew];
            }
        }
        _celWasEndEdit = null;
      }

    private void datagridview_CellEndEdit(object sender, DataGridViewCellEventArgs e)
    {
        _celWasEndEdit = dgvItems[e.ColumnIndex, e.RowIndex];
    }
