c# – 动态更改面板的大小

我正在实现一个需要在面板中拖放图像框的应用程序.图像框是从程序中动态添加的,因此我在面板中将autoscroll属性设置为true.但是当我拖出底部的框时面板尺寸减小.我在面板中放置了autosize属性false.面板停靠在另一个面板上.我想在运行时设置面板的大小.我怎样才能实现这一点.

public form1(int[,] dummy,int columnSize,int rowSize)
   {
       this.dummy= dummy;
       numOfColumns = columnSize;
        numOfRows = rowSize;
        getData();
        addIds = addIdArray;
        data = mylist;
        InitializeComponent();
        //panel1.MinimumSize = new Size(columnSize * 40,rowSize * 40);
        //panel1.Height = rowSize * 40;
        //panel1.Width = columnSize * 40;
        //panel4.Height = rowSize * 40;
        //panel4.Width = columnSize * 40;
        int x,y;
        Structures.EmptyRectSpace space = new Structures.EmptyRectSpace();
        for (int i = 0; i < data.Count; i++)// set picture Boxes 
        {
            space = (Structures.EmptyRectSpace)data[i];
            x = space.startingJ;
            y = space.startingI;
            int h,w;
            h = space.length;
            w = space.width;
 
             p = new PictureBox();
                p.Width = w * 40;
                p.Height = h * 40;
                p.BackColor = Color.DarkGreen;
                p.Image = Properties.Resources.v;
                p.BorderStyle = BorderStyle.FixedSingle;
                p.Name = addIdArray[i].ToString();
                p.Location = new Point((x + 1 - w) * 40,(y + 1 - h) * 40);
 
                this.panel1.Controls.Add(p);
        }
 
        foreach (Control c in this.panel1.Controls)
        {
            if (c is PictureBox)
            {
                c.MouseDown += new MouseEventHandler(pictureBox1_MouseDown);
            }
        }
        this.panel1.DragOver += new System.Windows.Forms.DragEventHandler(this.panel1_DragOver);
        panel1.DragOver += new DragEventHandler(panel1_DragOver);
        panel1.DragDrop += new DragEventHandler(panel1_DragDrop);
        panel1.AllowDrop = true;
        panel2.AllowDrop = true;
        foreach (Control c in this.panel2.Controls)
        {
            c.MouseDown += new MouseEventHandler(pictureBox1_MouseDown);
        }
        this.panel2.DragOver += new System.Windows.Forms.DragEventHandler(this.panel2_DragOver);
        panel2.DragOver += new DragEventHandler(panel2_DragOver);
        panel2.DragDrop += new DragEventHandler(panel2_DragDrop); 
    }

这是包含面板的表单的构造函数.当它加载时,必须将图片框添加到面板中并实现面板的拖放事件.

请帮帮我..

解决方法

除非我在代码中以编程方式设置最大宽度,否则我无法工作.设计师的最大宽度是多少并无关紧要(或者如果设置了最大宽度).

int newWidth = 200;
panel.MaximumSize = new Size(newWidth,panel.Height);
panel.Size = new Size(newWidth,panel.Height);
