Question

我有一个包含数据库中所有来宾的Listview

        public FormGuestManagement()
    {
        InitializeComponent();

        listViewGuests.View = View.Details;
        listViewGuests.GridLines = true;
        listViewGuests.Scrollable = true;
        listViewGuests.FullRowSelect = true;
        listViewGuests.HideSelection = false;
        var guests = Repository.GetAllGuests();

        foreach (var guest in guests)
        {
            ListViewItem lvData = new ListViewItem(guest.AccountID.ToString());

            lvData.SubItems.Add(guest.Username);
            lvData.SubItems.Add(guest.Email);
            lvData.SubItems.Add(guest.FirstName);
            lvData.SubItems.Add(guest.LastName);
            lvData.SubItems.Add(guest.TelephoneNumber);
            lvData.SubItems.Add(guest.AddressLine1);
            lvData.SubItems.Add(guest.AddressLine2);
            lvData.SubItems.Add(guest.City);
            lvData.SubItems.Add(guest.State);
            lvData.SubItems.Add(guest.Postcode);
            lvData.SubItems.Add(guest.Country);

            listViewGuests.Items.Add(lvData);
        }
    }

如何使用字符串搜索单个列（在本例中为guest.Firstname），并且只显示列表视图中与字符串匹配的值（隐藏其他列）？

感谢您的时间！

Answer 1

ListView控件不提供您想要的功能。为了模拟您描述的内容，每次过滤条件发生变化时，您都必须重建所需的列表。

或者您可以像一位评论者所建议的那样使用更强大的内容，例如DataGridView。此控件提供真正的行/列行为，并采用可绑定的DataSource。

LINQ可以做到这一点，应该很容易：

combofavorite.Items.Add("Report Type: " + cmbreporttype.Text + " Date From: " + dateTimePicker1.Text + " To: " + dateTimePicker2.Text);
            combofavorite.SelectedIndex = 0;
            MessageBox.Show("Add Report Type: " + cmbreporttype.Text + " Date From: " + dateTimePicker1.Text + " To: " + dateTimePicker2.Text + " TO Favorite", "Added to Favorite", MessageBoxButtons.OK, MessageBoxIcon.Information);

使用字符串搜索Listview子项
