in my datagridview?

推荐答案

尝试:

    ...
    dataGridView1.CellClick += new DataGridViewCellEventHandler(dataGridView1_CellClick);
    ...

void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
    {
    DataGridView dgv = sender as DataGridView;
    if (dgv != null)
        {
        DataGridViewButtonCell b = dgv.Rows[e.RowIndex].Cells[e.ColumnIndex] as DataGridViewButtonCell;
        }
    }

检查RowIndex 和ColumnIndex 的有效性可能是一个好主意，但这为您提供了这个主意.

It would probably be a good idea to check the RowIndex and ColumnIndex for validity, but that gives you the idea.

我的下一篇文章-这是摘录(我应该准备完整的文章准备明天提交)，我已经在设计时使用IDE在我的DataGridView中添加了一个命令按钮-称为dgLoadImage.列类型的DataGridViewButtonColumn将为您创建按钮.为了使用该按钮，我已经将CellContentClick事件添加到了DataGridView中.乍一看，此事件的代码看起来有些奇怪，因为它以if语句打开，当click事件位于按钮以外的任何列上时，该if语句会强制退出

In the example from my next article - here is an extract (I should have the complete article ready for submission tomorrow), I have used the IDE to add a command button to my DataGridView at design time - called dgLoadImage. A column type of DataGridViewButtonColumn will create the button for you. In order to use the button I have added a CellContentClick event to my DataGridView. At first glance the code for this event looks a little bizarre as it opens with an if statement that forces exit when the click event is on any column other than the button

 if (e->ColumnIndex != dgLoadImage->Index)
     return; // Hardcoded to only accept the event on the button column
 else
 {
    :
}

这只是我格外小心. CellContentClick事件只会对按钮列触发，因此在此示例中，我无需担心，但是，如果我的表单上有多个按钮，则需要确定哪个列触发了click事件并采取相应的行动.

This is just me being extra carefull. The CellContentClick event will only fire for button columns, so in this example I have nothing to worry about, however if I had more than one button on my form, then I need to determine which column triggered the click event and act accordingly.
