推荐答案

I已尝试您的样本，它的工作原理。您确实将事件绑定到 DataGridView ？

I have tried your sample and it works. Did you really bind the event to your DataGridView ?

请检查 InitializeComponent < YourFormName> .Designer.cs 类中的方法。
它真的有

Please check the InitializeComponent() Method in your <YourFormName>.Designer.cs class. Did it really has

this.dataGridView1.CellClick += 
  new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellClick);

并且你不会在代码中的另一个地方删除处理程序？

and you don't remove the handler at another place in code ?

MSDN页面中的DataGridViewButtonColumn可以这样说：

The DataGridViewButtonColumn MSDN page has this to say:

按钮点击，处理DataGridView.CellClick或DataGridView.CellContentClick事件。在事件处理程序中，您可以使用DataGridViewCellEventArgs.ColumnIndex属性来确定是否在按钮列中发生了点击。您可以使用DataGridViewCellEventArgs.RowIndex属性来确定点击是否发生在按钮单元格中，而不是列标题上。

To respond to user button clicks, handle the DataGridView.CellClick or DataGridView.CellContentClick event. In the event handler, you can use the DataGridViewCellEventArgs.ColumnIndex property to determine whether the click occurred in the button column. You can use the DataGridViewCellEventArgs.RowIndex property to determine whether the click occurred in a button cell and not on the column header.
