嗨HK33，



虽然你的问题很糟糕但我试着开始猜测可能会解决你的问题。你期待有人为你工作/思考，但是你不用费心去制定你的问题 - 请参阅OriginalGriffs评论。但是对于这种行为你并不孤单在这个论坛上 - 我只是可以'得到使用...



那就是说，让我们试着找到你的问题：



我假设（那些你不认为有人应该知道以帮助你的东西）：

*你使用 System.Windows.Forms.DataGridView

*您使用的是 CellClick 的事件System.Windows.Forms.DataGridView

*当你试图获取一个单元格时会发生异常使用CellClick处理程序（方法）中的EventArgs获得的索引



所以诀窍可能只是为你的处理程序添加一些逻辑。

Hi HK33,

Although your question is quite "BAD" I try to start the guessing to work out what may be your problem. You are expecting someone to "work/think" for you, but you don't bother to formulate your question with a little effort - see OriginalGriffs comment. But with this "behaviour" you are not alone on this forum - I just can't get "used" to it...

That said, let's try to find your Problem:

I assume (those things you didn't think someone should know in order to help you):
* You use a System.Windows.Forms.DataGridView
* You are using the CellClick Event of your System.Windows.Forms.DataGridView
* Your exception happens when you try to get a cell with the indices you got from the EventArgs inside a CellClick handler (method)

So the trick could be just to add some logic to your handler.

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    // No row was clicked (e.g. Header)
    if (e.RowIndex < 0)
    {

    }
    // No column was clicked (e.g. RowHeader)
    else if (e.ColumnIndex < 0)
    {

    }
    // valid cell
    else
    {
    }
}

如果这不能解决你的问题问题试着改善你的问题，并显示有问题/相关的代码。



亲切的问候

If this does not solve your problem try to improve your question and show the problematic/relevant code.

Kind regards

你好，

你可以在行点击事件上处理它。

在行点击或单击鼠标上写代码事件

Hello,
You can handle it on row click event.
write code on row click or cell click event

e.handle=false;
