推荐答案

我发现这个代码在论坛，它的工作。

I found this code in a forum, and it works.

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
  DataGridViewTextBoxEditingControl tb =(DataGridViewTextBoxEditingControl)e.Control;
  tb.KeyPress += new KeyPressEventHandler(dataGridViewTextBox_KeyPress);

  e.Control.KeyPress += new KeyPressEventHandler(dataGridViewTextBox_KeyPress);
}


private void dataGridViewTextBox_KeyPress(object sender, KeyPressEventArgs e)
{
  //when i press enter,bellow code never run?
  if (e.KeyChar==(char)Keys.Enter)
  {
    MessageBox.Show("You press Enter");
  }
}
