动态添加多个用户控件

动态添加多个相同用户控件，并使每个用户控件获取不同的内容。

用户控件代码：

 

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 using System.Web.UI;
 6 using System.Web.UI.WebControls;
 7 
 8 namespace xuyuanwang.myControl
 9 {
10     public partial class Lablexuyuan : System.Web.UI.UserControl
11     {
12         string a = "ok";
13         public string A
14         {
15             set
16             {
17                 a = value;
18             }
19             get
20             {
21                 return a;
22             }
23         }
24         protected void Page_Load(object sender, EventArgs e)
25         {
26                Label1.Text = A;
27             
28         }
29 
30     }
31 }

 

aspx页面代码：

 

 public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
           
            myControl.Lablexuyuan ctl = (myControl.Lablexuyuan)Page.LoadControl("myControl/Lablexuyuan.ascx");
            ctl.A = this.TextBox1.Text;

            ArrayList list = addl(ctl);
            for (int i = 0; i < list.Count; i++)
            {
                myControl.Lablexuyuan ctl2 = (myControl.Lablexuyuan)list[i];
                this.UpdatePanel1.ContentTemplateContainer.Controls.Add(ctl2);
            } 

        }
        private System.Collections.ArrayList addl(myControl.Lablexuyuan l)
        {
            System.Collections.ArrayList list = null;
            if (Session["a"] != null)
            {
                list = (ArrayList)Session["a"];


            }
            else
            {
                list = new ArrayList();

            }
            list.Add(l);
            Session["a"] = list;
            return list;
        }
