如何添加文本框到动态创建的图片盒

Question

我有一个程序，当我点击按钮时动态创建可移动的图片框。当我点击图片框时，我需要做一些事情，当我可以写这个图片框的描述（名称，...）时，此点击将添加到我的动态创建的图片框中一个新的文本框。这个文本框应该能够移动与图片框。

using System; 
using System.Collections.Generic; 
using System.Drawing; 
using System.Windows.Forms; 


    namespace WindowsFormsApplication1 
    { 

     public partial class Form1 : Form 
     { 
      List<PictureBox> pictureboxes = new List<PictureBox>(); 

      public Form1() 
      { 
       InitializeComponent(); 
      } 

      private void AddPictureBox(string imagePath) 
      { 
       var pb = new PictureBox(); 
       pb.Name = "picturebox" + pictureboxes.Count; 
       pb.Location = new Point(pictureboxes.Count * 100, 100); 
       pb.Size = new Size(70, 70); 
       pb.BorderStyle = BorderStyle.None; 
       pb.SizeMode = PictureBoxSizeMode.StretchImage; 
       this.Controls.Add(pb); 

       pb.Image = Image.FromFile(imagePath); 
       pb.Refresh(); 
       pb.MouseDown += new MouseEventHandler(picMouseDown); 
       pb.MouseMove += new MouseEventHandler(picMouseMove); 
       pb.MouseUp += new MouseEventHandler(picMouseUp); 

       pictureboxes.Add(pb); 

       Invalidate(); 
      } 

      private void router_Click(object sender, EventArgs e) 
      { 
       AddPictureBox(@"D:\\router.jpg"); 

      } 

      private void Form1_Load(object sender, EventArgs e) 
      { 

      } 

      int x = 0; 
      int y = 0; 
      bool drag = false; 

      private void picMouseDown(object sender, MouseEventArgs e) 
      { 
       // Get original position of cursor on mousedown 
       x = e.X; 
       y = e.Y; 
       drag = true; 
      } 

      private void picMouseMove(object sender, MouseEventArgs e) 
      { 
       if (drag) 
       { 
        PictureBox pb = (PictureBox)sender; 
        // Get new position of picture 
        pb.Top += e.Y - y; 
        pb.Left += e.X - x; 
        pb.BringToFront(); 

        Invalidate(); 
       } 
      } 

      private void picMouseUp(object sender, MouseEventArgs e) 
      { 
       drag = false; 
      } 

      private void switch1_Click(object sender, EventArgs e) 
      { 
       AddPictureBox(@"D:\HP ProBook 450\Desktop\Grafika\switch1.png"); 

      } 

      private void panel1_Paint(object sender, PaintEventArgs e) 
      { 

      } 

      private void pc_Click(object sender, EventArgs e) 
      { 
       AddPictureBox(@"D:\HP ProBook 450\Desktop\pc.jpg"); 

      } 

      private void server_Click(object sender, EventArgs e) 
      { 
       AddPictureBox(@"D:\HP ProBook 450\Desktop\server.png"); 


      } 
    } 

感谢您的任何帮助:)。

可以在代码TextBox添加到PictureBox这样的：

TextBox newTextBox = new TextBox(); 
newTextBox.Parent = yourPictureBox; 
// place it e.g. to the left bottom: 
newTextBox.Location = new Point(10, yourPictureBox.Height - newTextBox.Height); 

注意，这将增加TextBox到Controls集合PB的;所以它会坐在的顶部的PictureBox;所以，是的，它会随着PictureBox移动，但它也会隐藏一部分或PB！

如果您只是想将它们分组，请将它们都添加到Panel之类的东西中，再次将它们设置为Parent！

另请注意，您无法在设计器中执行此操作; PictureBox并非真正意味着作为Container ..

只要你有一个对它的引用，如何创建PictureBox并不重要。
