I have a datagridview in a .NET winform app. I would like to rightclick on a row and have a menu pop up. Then i would like to select things such as copy, validate, etc

我怎样A）菜单弹出B）发现哪一行是正确的点击。我知道我可以使用的selectedIndex但我应该能够右键单击不改变选择什么呢？现在我可以用选择的索引，但如果有一种方式来获得数据而不会改变被选中那么这将是有益的。

How do i make A) a menu pop up B) find which row was right clicked. I know i could use selectedIndex but i should be able to right click without changing what is selected? right now i could use selected index but if there is a way to get the data without changing what is selected then that would be useful.

推荐答案

您可以使用CellMouseEnter和CellMouseLeave跟踪鼠标当前悬停的行号。

You can use the CellMouseEnter and CellMouseLeave to track the row number that the mouse is currently hovering over.

然后使用ContextMenu对象以显示弹出式菜单，自定义当前行。

Then use a ContextMenu object to display you popup menu, customised for the current row.

下面是我的意思一个快速和肮脏的例子...

Here's a quick and dirty example of what I mean...

private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        ContextMenu m = new ContextMenu();
        m.MenuItems.Add(new MenuItem("Cut"));
        m.MenuItems.Add(new MenuItem("Copy"));
        m.MenuItems.Add(new MenuItem("Paste"));

        int currentMouseOverRow = dataGridView1.HitTest(e.X,e.Y).RowIndex;

        if (currentMouseOverRow >= 0)
        {
            m.MenuItems.Add(new MenuItem(string.Format("Do something to row {0}", currentMouseOverRow.ToString())));
        }

        m.Show(dataGridView1, new Point(e.X, e.Y));

    }
}
