为什么搜索按钮点击了AddGuest的验证器？

Question

这是用于显示网站首页的default.aspx文件。 现在，当我按下搜索按钮时，即使编写了重定向代码，它也不会重定向。 仅当文本框中有一些数据时，它才会重定向。 为什么会这样呢？

这是代码：

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


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

    }

    protected void add_Click(object sender, EventArgs e)
    {
        String guestName = name.Text;
        String guestPhone = phone.Text;

        GuestData guestData = new GuestData();

        guestData.GuestName = guestName;
        guestData.GuestPhone = guestPhone;

        GuestDAL guestDAL = new GuestDAL();
        bool isAdded = guestDAL.AddGuest(guestData);
        if (isAdded)
        {
            ClientScript.RegisterStartupScript(this.GetType(), "", "<script ='text'/'javascript'> alert('Guest is Added');</script>");
        }
        else
        {
            ClientScript.RegisterStartupScript(this.GetType(), "", "<script ='text'/'javascript'> alert('Guest is not Added');</script>");
        }



    }


    protected void search_Click(object sender, EventArgs e)
    {

        Response.Redirect("Search.aspx");   
    }
}

这是default.aspx.cs：

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <style>
   .param{
       width:200px;
       padding:20px;
   }
   .userbackground{
       margin-left:14px;
   }
   .centering{
       width:300px;
   }
   .button_style{
       padding:10px;
   }
   .form_style{
       margin-top:5px;
   }
    </style>
</head>
<body>
    <form id="form1" runat="server">
        <div class="centering" style="margin-left:auto;margin-right:auto;">

        <div class="form_style">
           <span class="param">Guest Name :</span>
            <asp:TextBox ID="name" runat="server" CssClass="userbackground"></asp:TextBox>
            <asp:RequiredFieldValidator runat="server" ID="reqName" ControlToValidate="name"  errormessage="*"><span style="COLOR: red">*</span></asp:RequiredFieldValidator>
        </div>

        <div class="form_style">
           <span class="param">Guest Number :</span>
            <asp:TextBox ID="phone"  runat="server"></asp:TextBox>
            <asp:RequiredFieldValidator runat="server" Display="Dynamic" ID="RequiredFieldValidator1" ControlToValidate="name"  errormessage="*"><span style="COLOR: red">*</span></asp:RequiredFieldValidator>
        </div>

            <div class="button_style" align="center">
            <asp:Button ID="add" Text="Add Guest" runat="server" OnClick="add_Click" />
            <asp:Button ID="search" Text="Search it" runat="server" OnClick="search_Click"></asp:Button>
            </div>
         </div>

    </form>
</body>
</html>

没有数据，即使我们单击搜索按钮“ *”也显示在文本框的侧面。

将ValidationGroup与add button和RequiredFieldValidator 。 像下面

<div class="centering" style="margin-left:auto;margin-right:auto;">

    <div class="form_style">
       <span class="param">Guest Name :</span>
        <asp:TextBox ID="name" runat="server" CssClass="userbackground"></asp:TextBox>
        <asp:RequiredFieldValidator runat="server" ID="reqName" ControlToValidate="name" ValidationGroup="a"  errormessage="*"><span style="COLOR: red">*</span></asp:RequiredFieldValidator>
    </div>

    <div class="form_style">
       <span class="param">Guest Number :</span>
        <asp:TextBox ID="phone"  runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator runat="server" Display="Dynamic" ID="RequiredFieldValidator1" ValidationGroup="a" ControlToValidate="name"  errormessage="*"><span style="COLOR: red">*</span></asp:RequiredFieldValidator>
    </div>

        <div class="button_style" align="center">
        <asp:Button ID="add" Text="Add Guest" runat="server" ValidationGroup="a" OnClick="add_Click" />
        <asp:Button ID="search" Text="Search it" runat="server" OnClick="search_Click"></asp:Button>
        </div>
     </div>
