在datagridview控件中按Enter键时，将焦点设置为下一个单元格(Set focus to next cell when pressing enter key in datagridview control)

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
        {

            if (e.KeyCode == Keys.Enter)
            {
                e.SuppressKeyPress = true;
                int iColumn = dataGridView1.CurrentCell.ColumnIndex;
                int iRow = dataGridView1.CurrentCell.RowIndex;
                if (iColumn == dataGridView1.Columns.Count - 1)
                    dataGridView1.CurrentCell = dataGridView1[0, iRow + 1];
                else
                    dataGridView1.CurrentCell = dataGridView1[iColumn + 1, iRow];

            }
        }

private   void  dataGridView1_KeyDown（ object  sender，KeyEventArgs e）
 {
 
  if （e.KeyCode == Keys.Enter）
 {
 e .SuppressKeyPress =  true ; 
  int  iColumn = dataGridView1.CurrentCell.ColumnIndex; 
  int  iRow = dataGridView1.CurrentCell.RowIndex; 
  if （iColumn == dataGridView1.Columns.Count  -   1 ）
 dataGridView1 .CurrentCell = dataGridView1 [ 0 ，iRow +  1 ]; 
  else  
 dataGridView1.CurrentCell = dataGridView1 [iColumn +  1 ，iRow]; 
 
} 
}
