推荐答案

这里有一些关于设置 DataGridViewButtonColumn 中出现的按钮的 Enabled 属性的问题的帮助.

Here's some help with the problem of setting the Enabled property of the Buttons that appear in a DataGridViewButtonColumn.

您需要扩展 DataGridViewButtonColumn 以创建您自己的带有禁用按钮的 DataGridView 列.MSDN 上的这篇文章 详细介绍了如何执行此操作.

You'll need to extend DataGridViewButtonColumn to create your own DataGridView column with disable-able buttons. This article on MSDN details how to do this.

这篇文章有很多代码，我鼓励你仔细看看，但你真正需要做的就是将文章中的以下类复制并粘贴到你的项目中:
-- DataGridViewDisableButtonColumn
-- DataGridViewDisableButtonCell

The article has a lot of code, and I encourage you to take a close look, but all you really need to do is copy and paste into your project the following classes found in the article:
-- DataGridViewDisableButtonColumn
-- DataGridViewDisableButtonCell

完成此操作后，您将能够将 DataGridViewDisableButtonColumn 添加到您的 DataGridView.使用在自定义列中公开的公共 Enabled 属性来设置每个单元格的 Button 控件的 Enabled 属性.由于您想设置列中所有按钮的 Enabled 属性，您可以编写一个辅助方法来循环遍历 DataGridView 中的所有行并设置 Enabled 属性:

Once you do this you will be able to add DataGridViewDisableButtonColumns to your DataGridView. Use the public Enabled property exposed in your custom column to set the Enabled property of each cell's Button control. Since you want to set the Enabled property of all the Buttons in the column you can write a helper method that loops through all rows in your DataGridView and sets the Enabled property:

private void SetDGVButtonColumnEnable(bool enabled) {
    foreach (DataGridViewRow row in dataGridView1.Rows) {
        // Set Enabled property of the fourth column in the DGV.
        ((DataGridViewDisableButtonCell)row.Cells[3]).Enabled = enabled;
    }
    dataGridView1.Refresh();
}
