添加选择的所有快捷键（Ctrl + A键）为.NET列表视图？ [英] Adding a select all shortcut (Ctrl + A) to a .net listview?

问题描述

喜欢的科目说，我有一个列表视图，我想补充的<大骨节病>控制 + <大骨节病> A 选择所有的快捷方式了。我的第一个问题是，我无法弄清楚如何以编程方式选择列表视图的所有项目。现在看来似乎应该是比较容易的，比如 ListView.SelectAll（）或 ListView.Items.SelectAll（），但是，这并不出现这种情况。我的下一个问题是如何定义的的ListView 快捷键。难道我这样做是在的KeyUp 事件，但你会怎么检查两个presses一次？或者是您设置的属性？

Like the subject says I have a listview, and I wanted to add the Ctrl + A select all shortcut to it. My first problem is that I can't figure out how to programmatically select all items in a listview. It seems like it should be relatively easy, like ListView.SelectAll() or ListView.Items.SelectAll(), but that doesn't appear to be the case. My next problem is how to define the keyboard shortcut for the ListView. Do I do it in a KeyUp event, but then how would you check two presses at once? Or is it a property that you set?

任何帮助将是巨大的。

推荐答案

您可以像这样同时完成：

You could accomplish both with something like this:

private void listView1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.A && e.Control)
    {
        listView1.MultiSelect = true;
        foreach (ListViewItem item in listView1.Items)
        {
            item.Selected = true;
        }
    }
}
