在消息框C＃中顯示所有列表視圖項

Question

我有一個帶子項的列表視圖。 前5個子項目是名稱，項目，總價，地址和電話。

其余子項目包含我為訂單顯示的過去列表。

這是一個比薩店計划，我希望它能夠獲得客戶的信息和訂單。

我可以獲取信息，但無法獲取其余訂單。

我想知道如何才能顯示剩余的訂單。

示例訂單：

Name: Claud
Items: 3
Total: 10.99
Address: (Blank)
Telephone: (Blank)
Order: Small Pizza
       -Bacon
       BreadSticks

現在我的消息框看起來像這樣：

Name: Claud
Items: 3
Total: 10.99
Address: (Blank)
Telephone: (Blank)
Order: Small Pizza

所以我只希望它顯示-Bacon和BreadSticks。

源代碼：

  private void CustomerInfo_Click(object sender, EventArgs e)
    {
        ListViewItem customers = new ListViewItem(fullName.Text);
        customers.SubItems.Add(totalcount.ToString());
        customers.SubItems.Add(total.ToString());
        customers.SubItems.Add(Address.Text);
        customers.SubItems.Add(telephone.Text);
        for (int i = 0; i < OrderlistBox.Items.Count; i++)
        {
            customers.SubItems.Add(OrderlistBox.Items[i].ToString());
        }
        Customers.Items.Add(customers);

        MessageBox.Show("Sent order for " + fullName.Text.ToString() + " to screen.");
        //CLEAR ALL FIELDS
        OrderlistBox.Items.Clear();
        fullName.Text = "";
        Address.Text = "";
        telephone.Text = "";
        totalDue.Text = "";
        totalItems.Text = "";
    }

    private void customerInformationToolStripMenuItem_Click(object sender, EventArgs e)
    {
        if (Customers.SelectedItems.Count != 0)
        {
            MessageBox.Show("Name: " + Customers.SelectedItems[0].SubItems[0].Text + "\n" +
                            "Adress: " + Customers.SelectedItems[0].SubItems[3].Text + "\n" +
                            "Telephone: " + Customers.SelectedItems[0].SubItems[4].Text + "\n" +
                            "Order: " +Customers.SelectedItems[0].SubItems[5].Text);
        }
    }

您可以通過創建充當消息框的新winform來創建自定義消息框。 在其上創建公共屬性，以傳遞所選項目的值，例如：

然后在您的表格上：

 private void customerInformationToolStripMenuItem_Click(object sender, EventArgs e)
    {
        if (Customers.SelectedItems.Count != 0)
        {
            var myformmessagedialog = new MyFormMessageDialog
            {

name = Customers.SelectedItems[0].SubItems[0].Text,
adress=Customers.SelectedItems[0].SubItems[3].Text,
telephone=Customers.SelectedItems[0].SubItems[4].Text
              };
              myformmessagedialog.ShowDialog();
        }
    }

您的MessageBoxDialogform：

MyFormMessageDialog : Form
{
  public MyFormMessageDialog()
    {
        InitializeComponent();
    }
    public string name;
    public string adress;
    public string telephone;

     private void MyFormMessageDialog_Load(object sender, EventArgs e)
    {

        lblName.Text = name;
        lbladdress.Text = adress;
        telephone.Text telephone;

       //if you are saving ado.net stuff 
       //query username where name = name then bind it on a list box or a combo box 
       var Orderdata = //you retrieve info via DataTable;
       lstOder.Items.Clear();
       foreach (DataRow data in Orderdata.Rows)
            {
                var lvi = new ListViewItem(data["Order"].ToString());
                // Add the list items to the ListView
                lstlstOder.Items.Add(lvi);
       }


    }
 }
