推荐答案

在keydown处理代码尝试如下：

Handle code in keydown try like this:

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
       {
           if (e.KeyCode == Keys.Enter)
           {
               int columnindex = dataGridView1.CurrentCell.ColumnIndex;
               int rowindex = dataGridView1.CurrentCell.RowIndex;

               if (columnindex < dataGridView1.ColumnCount - 1)
               {
                   columnindex++;
               }
               else
               {
                   columnindex = 0;
                   rowindex++;
               }

               if (rowindex == dataGridView1.RowCount)
                   dataGridView1.Rows.Add();

               dataGridView1.CurrentCell = dataGridView1[columnindex, rowindex];
               e.Handled = true;
           }
       }
