推荐答案

private void dataGridView1_EditingControlShowing(object sender,
    DataGridViewEditingControlShowingEventArgs e)
{
    dataGridView1.EditingControl.KeyPress -= new KeyPressEventHandler(MyKeyPressHandler);
    dataGridView1.EditingControl.KeyPress += new KeyPressEventHandler(MyKeyPressHandler);
}

通过检查EditingControlShowing处理程序的参数，您可以选择要验证的单元格，也可以对每个单元格使用不同的按键处理程序.
请注意，按键处理程序在添加之前已被删除.这是为了防止在您继续进入单元格时建立相同的处理程序.删除不存在的处理程序(在第一次进入时)不是问题.

By checking the arguments to the EditingControlShowing handler you can be selective about the cells you decide to validate, or use different key press handlers for each cell.
Note that the key press handler is removed before it is added. This is to prevent a build up of identical handlers when you keep entering a cell. Removing a handler which doesn''t exist (on first entry) isn''t a problem.
