双击 ListView 的一行时选择了哪一列 [英] Which Column was selected when DoubleClick a Row of a ListView

问题描述

首先，我不是在谈论单击列标题.我说的是选定行中的项目.
我有一个 ListView，想要双击所选行中的 username 列并将用户名复制到剪贴板.
如果我双击所选行的 password 列，将密码复制到剪贴板.

First of all, I'm not talking about clicking the column header. I'm talking about the item in a selected row.
I have a ListView and wanting to double click the username column in a selected row and copy username to clipboard.
If I double click the password column of a selected row, copy the password to clipboard.

显然我们可以知道选择了哪一行，但我不知道如何捕获在该行中双击哪一列.
这可能吗?

Obviously we can tell what row is selected, but I can't figure out how to capture what column was double clicked within that row.
Is that possible?

人们想要代码，所以在这里你去吧，记住只能选择单行所以是的，0 会工作:

People want code so here ya go, keep in mind only single row can be selected so yes, 0 will work:

ListViewItem lvi = this.contentListView.SelectedItems[0];
string pass = lvi.SubItems[5].Text;

推荐答案

您可以使用 ListView HitTest 方法.它返回一个 ListViewHitTestInfo 对象.
它的 SubItem 属性为您提供ListViewSubItem 对象被点击:

You can use the ListView HitTest method. It returns a ListViewHitTestInfo object.
Its SubItem property gives you the ListViewSubItem object clicked:

可以使用 ListViewItem.SubItems.IndexOf() 方法.ListViewItem 和 SubItem 都在 ListViewHitTestInfo 对象中被引用.

The corresponding ColumnHeader object can be identified using the ListViewItem.SubItems.IndexOf() method. Both the ListViewItem and SubItem are referenced in the ListViewHitTestInfo object.

private void listView1_MouseDoubleClick(object sender, MouseEventArgs e)
{
    var hitInfo = listView1.HitTest(e.Location);
    if (hitInfo.SubItem == null || string.IsNullOrEmpty(hitInfo.SubItem.Text)) return;

    int subItemIndex = hitInfo.Item.SubItems.IndexOf(hitInfo.SubItem);
    var column = listView1.Columns[subItemIndex];

    // Do whatever you need to do with the SubItem text
    string result = ProcessSubItemText(hitInfo.SubItem.Text, column);
    Clipboard.SetText(result, TextDataFormat.UnicodeText);
}
