100分求思路

自定义控件，名字叫UCControl,在主窗体里根据需要for 循环 new UCControl，最后加到主控窗体Controls里就可以了

谢谢！忘了说了是桌面程序，非web项目

生成“小方块”当然就写 var x= new 小方块();啦。而插入控件，遵循所有可包括内容控件的（父类）接口协议，那么当然就是向其 Child 集合属性（对于15年前的 winform 控件就是 Controls 集合属性）插入x。可以参考我以前回复的一个帖子：http://bbs.csdn.net/topics/390820186

你的“小方块”应该是一个独立的UserConrol，这是你的程序设计的重点。至于写上5、6行代码把多个“小方块”放到布局控件内部（例如放到Grid内部），其实不需要什么技术。

private void button8_Click(object sender, EventArgs e)
        {
            int num = 0;
            DataTable dt = GetData();//你可以将数据库里数据取出填充到DataTable 中，
            dataGridView1.DataSource = dt;
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                int n = dataGridView1.Rows.Count - 1;
                for (int j = 0; j < dt.Columns.Count; j++)
                {                    int h = num / 3;
                    int v = num % 3;
                    TextBox txt = new TextBox();
　
                    txt.Location = new Point(h * 37 + 19, v * 35 + 56);　
                    txt.Size = new Size(30, 29);
                    txt.Margin = new System.Windows.Forms.Padding(3);
                    txt.Text = dt.Rows[i].ItemArray[j].ToString();
                    //在groupBox1中增加TextBox；
                    this.groupBox1.Controls.Add(txt);
                    num++;
                }
                n++;
            }
        } private System.Data.DataTable GetData()

            tableInfo.Columns.Add(dctime);
            tableInfo.Columns.Add(dcCity);
            tableInfo.Columns.Add(dcCount);
            DataRow dr = tableInfo.NewRow();
            dr["Time"] = "1:00";
            dr["City"] = "10";
            dr["Count"] = "15";
            tableInfo.Rows.Add(dr);
            DataRow dr1 = tableInfo.NewRow();
            dr1["Time"] = "2:00";

            tableInfo.Rows.Add(dr2);

            dr4["City"] = "15";
            dr4["Count"] = "11";
            tableInfo.Rows.Add(dr4);            DataRow dr5 = tableInfo.NewRow();

            dr7["Count"] = "13";
            tableInfo.Rows.Add(dr7);
            return tableInfo;
        }

用Panel、PictureBox都可以，自己画下。也可以做成用户控件。怕麻烦也可以用Grid冒充。

可以参考下，拍一行 lanble 的代码 dt1 = Me.Pm_DataOp_sqlide.OpenDatatable(strcmd)            Dim row1 As DataRow
            Me.Panel4.Controls.Clear()
            Dim v_n As Integer = 100
            Dim n2 As Integer = 0            For Each row1 In dt1.Rows
                Dim lab1 As New Label
                lab1.Tag = row1.Item("group_no")
                lab1.Text = "Group：" & row1.Item("group_no")
                Me.Panel4.Controls.Add(lab1)
                lab1.Width = 60
                lab1.Height = Me.Panel4.Height
                lab1.Left = lab1.Width * n2 + 5 * n2
                'lab1.AutoSize = True
                'lab1.Dock = DockStyle.Left
                'lab1.SendToBack()
                lab1.BringToFront()
                Dim v_g_n As Integer
                v_g_n = 50 + v_n
                If v_g_n > 255 Then
                    v_g_n = 255
                End If
                lab1.BackColor = System.Drawing.Color.FromArgb(255, 50 + 0, v_g_n, 50)
                AddHandler lab1.Click, AddressOf Me.Labelx_Click                v_n = v_n + 15                n2 = n2 + 1            Next

你怎么知道是 Label 呢？

usecontrol+flowlayoutpanel
或直接listview

你怎么知道是 Label 呢？
什么意思....

一个小方块（div+css就出来了，如果还需美观一点，配点背景图片类的）就是一个单元，包含相关数据加载业务逻辑，你下拉框选择多少item数量，就按需求输出循环输出多少个小方块就行了。

你的问题其实就是怎么循环出多个小方块，自己用BUTTON也好，自定义控件也好，把这个循环做出来就行了。自己查一下，动态循环控件foreach (Control c in Page.Controls)
{
if (c is Label)
{
Label l = c as Label; Response.Write("!!!!" + l.Text.ToString() + "<br />");
}
}你能循环出来了，其他的数据长度查出多少就循环多少个这不能算问题了
