I CALL 我又遇难了！Groupbox问题！

[APOLLO_TS]

页面就是两个groupbox，两个label

动态添加checkbox，结果就显示其中一个！到底哪个地方出问题了啊？

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication6
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void SetCheckBox(GroupBox gb,Label lb)
        {
            lb.Text = lb.Text + "----" + gb.Location.X.ToString()+"/"+gb.Location.Y.ToString();
            for (int a = gb.Location.Y + 12; a < gb.Location.Y + gb.Size.Height - 22; a = a + 22)
            {
                for (int b = gb.Location.X + 12; b < gb.Location.X + gb.Size.Width - 114; b = b + 112)
                {

                    CheckBox cb = new CheckBox() { Text = "GB_" + b.ToString() + "_" + a.ToString(), Name = "GB_" + b.ToString() + "_" + a.ToString() };
                    cb.Location = new System.Drawing.Point(b, a);
                    cb.Size = new System.Drawing.Size(108, 16);
                    gb.Controls.Add(cb);
                    lb.Text = lb.Text + "----" + cb.Name;
                }
            }

        }

        private void Form1_Load(object sender, EventArgs e)
        {
            SetCheckBox(this.groupBox1,this.label1);
            SetCheckBox(this.groupBox2, this.label2);
        }
    }
}

第二个groupbox 怎么就没添加进去呢？坐标没重复，名称没重复。god！

[风中飘过一行代码]

你给我说下你form的大小吧

for (int b = gb.Location.X + 12; b < gb.Location.X + gb.Size.Width - 114; b = b + 112) 这里产生的b的坐标重复了。所以生成的是一个。

位置不对了。。我只修改了一句话: CheckBox cb = new CheckBox() { Text = "GB_" + b.ToString() + "_" + a.ToString(), Name = "GB_" + b.ToString() + "_" + a.ToString() }; cb.Location = new System.Drawing.Point(b, a - gb.Location.Y); cb.Size = new System.Drawing.Size(108, 16); gb.Controls.Add(cb); lb.Text = lb.Text + "----" + cb.Name;

cb.Location 应该是相对坐标，给第二个group赋值的时候cb.Location = new System.Drawing.Point(b, a);中的a太大了。

mygod！我当成绝对定位用了！一句话就道出我的问题了！三Q ------------------- 目前一部分代码改成如下：

        /// <summary>
        /// 向GroupBox中添加CheckBox
        /// </summary>
        /// <param name="groupBox">指定的GroupBox</param>
        /// <param name="colOfUIItems">CheckBox属性的集合</param>
        /// <param name="evnForCheckBox">CheckBox要响应的点选事件</param>
        private void SetCheckBox(GroupBox groupBox, IEnumerable<UIItems> colOfUIItems,EventHandler evnForCheckBox)
        {
            //存储CheckBox对象
            Queue<CheckBox> que = new Queue<CheckBox>();
            var t = from d in colOfUIItems
                    select new CheckBox
                    {
                        Name = d.ItemName,
                        Text = d.Text,
                    };
            //CheckBox添加事件
            foreach (var item in t)
            {
                item.CheckedChanged +=evnForCheckBox;
                que.Enqueue(item);
            }
            //指定CheckBox在GroupBox中的坐标，坐标为相对坐标
            for (int y =20; y <groupBox.Size.Height - 22; y = y + 22)
            {
                for (int x =12; x <groupBox.Size.Width - 16; x = x + 112)
                {
                    if (que.Count > 0)
                    {
                        CheckBox cb = que.Dequeue();
                        cb.Location = new System.Drawing.Point(x, y);
                        cb.Size = new System.Drawing.Size(108, 16);
                        groupBox.Controls.Add(cb);
                    }
                }
            }
        }
