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 Picturebox，但现在我的 TextBox 没有给我任何值。我认为他们失焦了，或者他们的控件不再工作了，这是目前的代码：

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。

我如何才能将程序重新聚焦到表单上或执行任何可以再次激活框的操作？

我刚刚解决了这个问题，我只需要省去 InitializeComponent()，然后就可以了。事实证明，如果你这样做，已经存在的组件将被阻止，并且不能再在任何选项中进行更改。
