           }


      private void dataGridColumns()
       {
           for (int i = 0; i <= metroGrid1.Rows.Count - 1; i++)
           {
               string prodName = metroGrid1.Rows[i].Cells[0].Value.ToString();
               string prodRetailPrice = metroGrid1.Rows[i].Cells[1].Value.ToString();
               string prodQuantity = metroGrid1.Rows[i].Cells[2].Value.ToString();
               string prodTotalPrice = metroGrid1.Rows[i].Cells[3].Value.ToString();

           }
       }

推荐答案

与使用OpenFileDialog的方式相同或者类似：你在弹出窗口中创建属性，当弹出窗口关闭时，父窗体通过实例弹出窗口进行访问。

因为你使用ShowDialog，所以父代码将在该行冻结，然后在用户关闭弹出窗口时继续使用以下代码行。

The same way you do with a OpenFileDialog or similar: you create properties in the pop-up which the "parent" form accesses via the pop-up from instance when the pop-up closes.
Because you use ShowDialog, the "parent" code will freeze at that line and then continue with the following line of code when the user closes the pop-up.

这是使用静态 BindingList 的解决方案，程序代码：

Here is a solution using a static BindingList, Program code:

using System;
using System.Windows.Forms;
using System.ComponentModel;

namespace TestForm1
{
    static class Program
    {
        public static BindingList<MyClass> masterBindingList;

        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            //// Test data grid with BindingList.
            Application.Run(new Form1());
        }

        /// <summary>
        /// Simple class with one string.
        /// </summary>
        public class MyClass
        {
            public string Title { get; set; }
        }
    }
}

Form1代码：

Form1 code:

using System;
using System.ComponentModel;
using System.Windows.Forms;

namespace TestForm1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.Init();
        }

        private void Init()
        {
            Program.masterBindingList = new BindingList<Program.MyClass>();
            this.dataGridViewMaster.DataSource = Program.masterBindingList;
        }

        private void ButtonAddRowClick(object sender, EventArgs e)
        {
            var rowIndex = this.dataGridViewMaster.RowCount;
            this.AddRow(rowIndex);
            this.ScrollToRow(rowIndex);
        }

        /// <summary>
        /// Add new row via the BindingList.
        /// </summary>
        private void AddRow(int rowIndex)
        {
            var myRow = new Program.MyClass { Title = "Row " + rowIndex.ToString() };
            Program.masterBindingList.Add(myRow);
        }

        private void ScrollToRow(int rowIndex)
        {
            this.dataGridViewMaster.ClearSelection();
            this.dataGridViewMaster.FirstDisplayedScrollingRowIndex = rowIndex;
            this.dataGridViewMaster.Focus();
        }
    }
}

您可以将Form2设置为共享BindingList，如下所示：

You can set your Form2 to the shared BindingList as follows:

private void buttonShow_Click(object sender, EventArgs e)
{
    var form2 = new Form2();
    // form2.dataGridView1 Modifiers set to public in Designer.
    form2.dataGridView1.DataSource = Program.masterBindingList;
    form2.ShowDialog();
}

当然你也可以在 InitializeComponent（）之后在Form2中设置DataSource。

Of course you can also set the DataSource in Form2 after InitializeComponent().
