C# 我创建了一个新的图片框，现在我的文本框不会给我任何值

Question

我正在通过代码创建一个新的图片框，但现在我的文本框没有给我任何值。我认为他们失去了焦点，或者他们的控件不再工作，这是到目前为止的代码：

private void button1_Click(object sender, EventArgs e)
    {

        int ErrorCode = 0;
        string NewName = NewPointName.Text;
        int X, Y;

        Application.DoEvents();

        if (NewPointName.Text == "")
            ErrorCode = 1;
        else
            for (int i = 0; i < Names + 1; i++)
            {
                if (PointName[i] == NewName)
                    ErrorCode = 2;
            }
        if (ErrorCode > 0)
            MessageBox.Show("Error " + ErrorCode);
        else
        {
            if (Convert.ToInt32(NewPointXBox.Text) > 60)
                X = 60;
            else if (Convert.ToInt32(NewPointXBox.Text) < -60)
                X = -60;
            else if (NewPointXBox.Text == "")
                X = 0;
            else
                X = Convert.ToInt32(NewPointXBox.Text);

            if (Convert.ToInt32(NewPointYBox.Text) > 60)
                Y = 60;
            else if (Convert.ToInt32(NewPointYBox.Text) < -60)
                Y = -60;
            else if (NewPointYBox.Text == "")
                Y = 0;
            else
                Y = Convert.ToInt32(NewPointYBox.Text);

            Punkt.GiveName(NewName, Names);
            Punkt.GiveCoordinates(X, Y, Names);
            PointName[Names] = NewName;
            NewPointName.Text = "";
            NewPointXBox.Text = "";
            NewPointYBox.Text = "";
            Application.DoEvents();
            UpdatePoint();
            CreatePoint(X, Y, NewName, Names);
            Names++;
            ErrorCode = 0;
            NewName = "";
        }


    }

 public void CreatePoint(int X, int Y, string name, int i)
        {
            int StartPointX = 450, StartPointY = 450, Factor = 7;
            if (RadioG6060.Checked)
            {
                StartPointX = 454;
                StartPointY = 449;
                Factor = 7;
            }

            Dot[i] = new PictureBox();
            this.Controls.Add(Dot[i]);
            Dot[i].Name = "PB_" + name;
            Dot[i].Size = new Size(10, 10);
            Dot[i].Image = Image.FromFile("../Dot.png");
            Dot[i].Anchor = AnchorStyles.Left;
            Dot[i].Location = new Point(StartPointX, StartPointY);
            Dot[i].Visible = true;
            InitializeComponent();
            Dot[i].BringToFront();
            Dot[i].Location = new Point(Dot[i].Location.X + (X * Factor), Dot[i].Location.Y - (Y * Factor));
            Application.DoEvents();
        }

我认为是 this.controls.Add(Dot[i]) 把它扔掉了，因为现在我无法访问我的 NewPointName 文本框中的文本。

我怎样才能让程序重新回到表单上，或者做任何可以再次激活框的事情？

我刚刚解决了这个问题，我只需要省略InitializeComponent()，然后它就起作用了。事实证明，如果您这样做，已经存在的组件将被阻止，并且无法再在其自身的任何选项中进行更改。
