在c#Windows窗体中动态创建控件

我正在用C#Windows窗体为书店应用程序创建一个应用程序 我在这里所做的过程是
1.将书籍名称、书籍图像插入数据库。
2.现在我需要检索表单图像中的内容，但所有内容都应动态创建，如
如果我有两本书，则应创建带有图片框、按钮和教科书的面板，并在其中显示值。
如果我在DB中有三个EnterEID，则表示应创建三个图片框、按钮和教科书，并在表单中显示这些值。
有没有办法解决这个问题。

需要根据数据库中的“n”行数动态创建这些控件

有关我的问题的更多信息，请参见图片

创建一个包含图像、文本框和按钮的用户控件。迭代从数据库检索到的记录列表，并为每个项创建用户控件的新实例。将用户控件添加到父控件的控件集合

实现你想要的很简单。您只需要为每本书创建一些

UserControl

，或者

面板就可以了。我将介绍如何使用
面板
。大概是这样的：

public class BookPanel : Panel
{
    public string BookName
    {
        get { return text.Text; }
        set { text.Text = value; }
    }
    public Image BookCover
    {
        get { return pic.Image; }
        set { pic.Image = value; }
    }
    public event EventHandler BuyBook;
    public string BuyButtonText
    {
        get { return button.Text; }
        set { button.Text = value; }
    }        
    //inner child controls
    PictureBox pic = new PictureBox();
    TextBox text = new TextBox();
    Button button = new Button();
    public BookPanel()
    {
        pic.Parent = text.Parent = button.Parent = this;
        pic.Top = 5;
        text.Left = pic.Left = 5;
        button.Text = "Buy";
        button.Width = 50;
        button.Anchor = AnchorStyles.Right | AnchorStyles.Bottom;
        text.Anchor = AnchorStyles.Left | AnchorStyles.Bottom | AnchorStyles.Right;
        pic.Anchor = AnchorStyles.Left | AnchorStyles.Top | AnchorStyles.Right | AnchorStyles.Bottom;
        pic.SizeMode = PictureBoxSizeMode.StretchImage;
        button.Click += (s, e) =>
        {
            EventHandler handler = BuyBook;
            if (handler != null) handler(this, EventArgs.Empty);
        };
    }
    bool init;
    protected override void OnSizeChanged(EventArgs e)
    {            
        base.OnSizeChanged(e);
        if (!init)
        {
            text.Width = Width - button.Width - 12;
            button.Left = text.Right + 5;
            pic.Height = Height - 35;
            pic.Width = Width - 10;
            text.Top = pic.Bottom + 5;
            button.Top = text.Top - 2;
            init = true;
        }
    }
}

//Usage
bookPanel1.BookCover = yourImage;
//Try this to see how the Buy button works
bookPanel1.BuyBook += (s, e) => {
    MessageBox.Show(bookPanel1.BookName);
};

注意：上面的代码不完整，您没有完全的能力自定义
文本框、按钮和图片框的外观，但是您可以添加代码来实现，代码有点多。我认为对于一个简单的控件来说，就足够了。您还应该注意使用
Dock
属性、
Margin
和
Padding
属性以及其他布局和容器控件，如
Panel
、
FlowLayoutPanel
、
TableLayoutPanel
，自定义您自己的控件

要在
FlowLayoutPanel
中使用它，请尝试以下代码：

flowLayoutPanel1.AutoScroll = true;
for (int i = 0; i < 100; i++) {
   new BookPanel {
                Parent = flowLayoutPanel1, 
                Width = 150, 
                Height = 200,
                BorderStyle = BorderStyle.FixedSingle,
                BookCover = yourImageList[i]
    }.BuyBook += buyBook;
}
private void buyBook(object sender, EventArgs e){
   BookPanel book = sender as BookPanel;
   //your code goes here ....
}

flowLayoutPanel1.AutoScroll=true；
对于（int i=0；i<100；i++）{
新书架{
父级=flowLayoutPanel1，
宽度=150，
高度=200，
BorderStyle=BorderStyle.FixedSingle，
BookCover=您的图像列表[i]
}.BuyBook+=购买书；
}
私有void buyBook（对象发送者，事件参数e）{
BookPanel book=发送方作为BookPanel；
//你的代码在这里。。。。
}

使用UserControl构建自定义控件（图像、文本字段、按钮）（）
使用FlowLayoutPanel或TableLayoutPanel在窗体上添加控件
创建Winforms项目并添加此文件：

CtrlBuyBook.cs

using System;
using System.Drawing;
using System.Windows.Forms;

namespace UserControls
{
    public class CtrlBuyBook : UserControl
    {
        public int BookID { get; set; }

        public int Quantity
        {
            get { return (int)nudQuantity.Value; }
            set { nudQuantity.Value = value; }

        private void btnBuy_Click(object sender, System.EventArgs e)
        {
            OnBuyBook(EventArgs.Empty);
        }

            if (handler != null)
            {
                handler(this, e);
            }
        }

        private System.ComponentModel.IContainer components = null;
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);

            this.SuspendLayout();
            this.picCover.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
        | System.Windows.Forms.AnchorStyles.Left)
        | System.Windows.Forms.AnchorStyles.Right)));
            this.picCover.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
            this.picCover.Location = new System.Drawing.Point(4, 4);
            this.picCover.Name = "picCover";
            this.picCover.Size = new System.Drawing.Size(143, 167);
            this.picCover.TabIndex = 0;
            this.picCover.TabStop = false;

            this.btnBuy.Anchor = ((System.Windows.Forms.AnchorStyles)((System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Right)));
            this.btnBuy.Location = new System.Drawing.Point(95, 177);
            this.btnBuy.Name = "btnBuy";
            this.btnBuy.Size = new System.Drawing.Size(52, 20);
            this.btnBuy.TabIndex = 2;
            this.btnBuy.Text = "Buy";
            this.btnBuy.UseVisualStyleBackColor = true;

            this.nudQuantity.Location = new System.Drawing.Point(4, 177);
            this.nudQuantity.Name = "nudQuantity";
            this.nudQuantity.Size = new System.Drawing.Size(85, 20);
            this.nudQuantity.TabIndex = 3;

            this.Size = new System.Drawing.Size(150, 200);
            ((System.ComponentModel.ISupportInitialize)(this.picCover)).EndInit();
            ((System.ComponentModel.ISupportInitialize)(this.nudQuantity)).EndInit();

        private System.Windows.Forms.Button btnBuy;
        private System.Windows.Forms.NumericUpDown nudQuantity;
    }
}

然后在按钮的单击事件上添加以下代码：

var control = new CtrlBuyBook();
control.BookID = ++_bookCount;
control.Cover = null;
control.Quantity = 1;
control.BuyBook += new EventHandler<EventArgs>(control_BuyBook);
flpPanel.Controls.Add(control);

仅此而已。
我们是否可以将单行中的所有字段检索到相应的位置。。也就是说，我需要创建100个这样的字段，如果值在db@Lostis中为100，那么我们可以检索单行中的所有字段到相应的位置。。也就是说，我需要创建100个这样的字段，如果值在db@Lostis中为100，那么我们可以检索单行中的所有字段到相应的位置。。也就是说，如果值是100分贝，我需要创建100个。bcoz以上是为我需要的所有控件手动创建的@hitesh你的意思是从数据库获取所有数据并显示在表单上吗？这就是我在问题中提到的。。有没有办法解决这个问题@Hitesh..您可以使用listview控件执行此操作。只要看看我添加的链接，你也可以使用所有你需要的
