}
}
思考题：
验证控件列表和执行的验证结果由哪个对象维护？请给出验证成功弹出消息框的实现代码。
protected void Button1_Click(object sender, EventArgs e)
{
if (RequiredFieldValidator1.IsValid == true)
{
Response.Write("<script>alert('输入合法');</script");
}
}
注意：不同数据验证控件的使用方法，数据控件的属性。
DropdownList控件启用AutoPostBack.
必须输入6~12个数字或大小写英文字母的正则表达式：[0-9A-Za-z]{6,12}
