int NoOfTextBoxes = 5;
受保护的void Page_Load(对象发送者，EventArgs e)
{
}
受保护的void Button1_Click(对象发送者，EventArgs e)
{
//第一次调用此函数，并在第一时间在此处创建复选框
//在浏览器中输入值之后，然后单击button2(Button2_Click)
//但是当Button2_Click被执行时，值会丢失，因为它们会重新创建...
function_temp();
}
受保护的void Button2_Click(对象发送者，EventArgs e)
{
function_temp();
for(int cou = 1; cou< = NoOfTextBoxes; cou ++)
{
TextBox txt =新的TextBox();
txt =(TextBox)FindControl("text" + cou.ToString());
Response.Write(txt.Text +"
");
}
}
受保护的void function_temp()
{
for(int cou = 1; cou< = NoOfTextBoxes; cou ++)
{
TextBox txt =新的TextBox();
//分配文本框ID
txt.ID ="text" + cou.ToString();
Panel2.Controls.Add(txt);
