如何在按钮单击时一次使用多个验证器？ [英] How to use more than one validator at a time on button click ?

问题描述

我有2个文本框和3个下拉列表作为必填字段。我正在使用javascript和asp .net验证器进行验证。当我点击提交按钮时，所有5个验证器都应该有效。但在我的代码中只有一个验证器工作。 
我的javascript代码是：
 var Page_IsValid = false; 
 Page_IsValid = Page_ClientValidate（'valgrpCode'）; 
 Page_IsValid = Page_ClientValidate（'valgrpDescription'）; 
 Page_IsValid = Page_ClientValidate（'valgrpCategory'）; 
和我的asp代码是：
 <   asp：RequiredFieldValidator     ID   =  reqCode    runat   =  server    ErrorMessage   =  *    ControlToValidate   =  txtCode    ValidationGroup   =  valgrpCode    ForeColor   = 红色 > ;  <   / asp：RequiredFieldValidator  > ;  
 <   asp：RequiredFieldValidator     ID   =  reqDescription    runat   =  server    ErrorMessage   =  *    ControlToValidate   =  txtDescription    ValidationGroup   =   valgrpDescription    ForeColor  < span class =code-keyword> = 红色 >  <   / asp：RequiredFieldValidator  >  
 
 <   asp：RequiredFieldValidator     ID   =  reqCategory < span class =code-attribute>   runat   =  server    ErrorMessage   =  *    ControlToValidate   =  txtCategory    ValidationGroup   =  valgrpCategory    ForeColor   = 红色 >  <   / asp：RequiredFieldValidator  >  
 
并且在这里我显示*作为强制性消息。但我需要将标签的颜色更改为强制性消息。我为每个文本框和下拉列表添加了标签。

解决方案

您好，



每个验证控件只需使用一个验证组。

 <   asp：requiredfieldvalidator     id   =  reqCode    runat   =  server    errormessage   =  *    controltovalidate   =  txtCode    validationgroup   =  valgrpCode    forecolor   =  红色    xmlns：asp   = ＃unknown >  <   / asp：requiredfieldvalidator  >  
 <   asp：requiredfieldvalidator     id   =  reqDescription < span class =code-attribute>   runat   =  server    errormessage   =  *    controltovalidate   =  txtDescription    validationgroup   =   valgrpCode    forecolor  < span class =code-keyword> = 红色    xmlns：asp   = ＃unknown >  <   / asp：requiredfieldvalidator  >  
 
 <   asp：requiredfieldvalidator     id   =  reqCategory    runat   =  server    errormessage   =  *    controltovalidate   =  txtCategory    validationgroup   =  val grpCode    forecolor   = 红色    xmlns：asp   = ＃unknown >  <   / asp：requiredfieldvalidator  >  

Hi,
     I have 2 text boxes and 3 drop down lists as mandatory fields. I am using javascript and asp .net validator for validation. When I click on the submit button all the 5 validator should work. But in my code only one validator is working.
My javascript code is:
var Page_IsValid = false;
Page_IsValid =Page_ClientValidate('valgrpCode');
Page_IsValid = Page_ClientValidate('valgrpDescription');
 Page_IsValid = Page_ClientValidate('valgrpCategory');
and my asp code is:
<asp:RequiredFieldValidator ID="reqCode" runat="server" ErrorMessage="*" ControlToValidate="txtCode" ValidationGroup="valgrpCode" ForeColor="Red"></asp:RequiredFieldValidator>
<asp:RequiredFieldValidator ID="reqDescription" runat="server" ErrorMessage="*" ControlToValidate="txtDescription" ValidationGroup="valgrpDescription" ForeColor="Red"></asp:RequiredFieldValidator>

<asp:RequiredFieldValidator ID="reqCategory" runat="server" ErrorMessage="*" ControlToValidate="txtCategory" ValidationGroup="valgrpCategory" ForeColor="Red"></asp:RequiredFieldValidator>

and also here i am showing "*" as mandatory message.  But I need to change the color of label as mandatory message. I have added labels for each text boxes and drop down lists.

解决方案

Hello,

You have to use only one validation group for each validation control.

<asp:requiredfieldvalidator id="reqCode" runat="server" errormessage="*" controltovalidate="txtCode" validationgroup="valgrpCode" forecolor="Red" xmlns:asp="#unknown"></asp:requiredfieldvalidator>
<asp:requiredfieldvalidator id="reqDescription" runat="server" errormessage="*" controltovalidate="txtDescription" validationgroup="valgrpCode" forecolor="Red" xmlns:asp="#unknown"></asp:requiredfieldvalidator>
 
<asp:requiredfieldvalidator id="reqCategory" runat="server" errormessage="*" controltovalidate="txtCategory" validationgroup="valgrpCode" forecolor="Red" xmlns:asp="#unknown"></asp:requiredfieldvalidator>
