在asp.net中有两种容器控件，其中包括panel和placeholder控件。
使用panel控件可以对控件进行分组。一帮助组织web窗体也的内容，将控件组织在面板中，可提供有关在运行时控件应如何分页显示的信息。这里也就是我们所说的在一个页面中通过“提交”或“下一步”按钮来显示不同的虚假页面，即通过隐藏可以实现，还有panel的外观属性，来设置panel的外观特性。

                }

                protected void Button1_Click(object sender, EventArgs e)
                {
                        this.Panel1.Visible = false;//点击按钮“下一步”是panel1隐藏
                        this.Panel2.Visible = true;//同时panel2显示出来
                        this.xusername.Text = this.username.Text;//把用户的信息放到自定义的label中，感觉很麻烦，希望会有更好的办法
                        this.xpassword.Text = this.password1.Text;
                        this.xtelephone.Text = this.telephone.Text;
                    
                }

                protected void Button2_Click(object sender, EventArgs e)
                {

                        this.Panel3.Visible = true;//同时panel3显示出来
                
                }
        }
}

整个流程图比较简单，运用的主要是textbox控件，label控件，验证控件，Button控件，panel容器控件，其中验证空间运用的比较粗糙，继续改进。
