Register.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Collections;

public partial class Register : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ArrayList ar = new ArrayList();
for (int i = 1; i <= 18; i++)
{
ar.Add("头像" + i);
}
this.DropDownList1.DataSource = ar;
this.DropDownList1.DataBind();
DropDownList1.Items.Insert(0, "请选择头像……");

ArrayList year = new ArrayList();
for (int i = 1989; i <= 1998; i++)
{
year.Add(i);
}
this.DropDownList2.DataSource = year;
this.DropDownList2.DataBind();
DropDownList2.Items.Insert(0, "1988");

ArrayList yue = new ArrayList();
for (int i = 2; i <= 12; i++)
{
yue.Add(i);
}
this.DropDownList3.DataSource = yue;
this.DropDownList3.DataBind();
DropDownList3.Items.Insert(0, "1");

ArrayList day = new ArrayList();
for (int i = 2; i <= 31; i++)
{
day.Add(i);
}
this.DropDownList4.DataSource = day;
this.DropDownList4.DataBind();
DropDownList4.Items.Insert(0, "1");

}
//Image1.ImageUrl = "~/image/1.jpg";
}

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
int m = DropDownList1.SelectedIndex;
for (int i = 1; i <= 18; i++)
{
if (m == i)
{
Image1.ImageUrl= "~/image/"+i+".jpg";
}
}
}

}

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}
