Question

我有一个包含子项目的列表视图。前5个子项是名称，项目，总价，地址和电话。

其余的子项包含我为订单显示的过去列表。

这是比萨店计划，我希望它能够获得客户信息和订单。

我可以获取信息，但无法获得剩余的订单。

我想知道如果有意义的话我怎么能显示我的其余订单。

示例顺序：

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

现在我的消息框看起来像这样：

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

所以我只想让它显示-Bacon和BreadSticks。

源代码：

  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);
        }
    }

您可以通过创建充当消息框的新winform来创建自定义消息框。在其上创建公共属性以传递选定项的值，如：

然后在你的表格上：

 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);
       }


    }
 }

希望这对你有所帮助。此致
