如何将验证限制到特定的触发器？ [英] How to limit validation to a particular trigger?

问题描述

有没有办法限制验证器控件对特定事件或触发器的验证？说，我想要我的验证器1只有当button1被点击被激活，并且validator2只有当button2被点击被激活。如何在asp.net中执行此操作？

解决方案

ValidationGroups 是您要查找的内容（ASP.NET> = 2.0）

验证组允许您将页面
上的验证控件组织为一组。每个验证组可以独立执行验证页面上其他验证组的
。

 < asp：textbox id =AgeTextBox
 runat =服务器> 
< / asp：textbox> 
 
& nbsp; 
 
< asp：requiredfieldvalidator id =RequiredFieldValidator1
 controltovalidate =AgeTextBox
 validationgroup =PersonalInfoGroup
 errormessage =输入你的年龄 
 runat =服务器> 
< / asp：requiredfieldvalidator> 
 
< br />< br /> 
 
<！ - 当Button1被点击时，只有验证
控件是PersonalInfoGroup 
的一部分被验证.--> 
< asp：button id =Button1
 text =验证
 causesvalidation =true
 validationgroup =PersonalInfoGroup
 runat =Server /> 
 
< br />< br /> 
 
< asp：textbox id =CityTextBox
 runat =服务器> 
< / asp：textbox> 
 
& nbsp; 
 
< asp：requiredfieldvalidator id =RequiredFieldValidator2
 controltovalidate =CityTextBox
 validationgroup =LocationInfoGroup
 errormessage =输入城市名称。 
 runat =服务器> 
< / asp：requiredfieldvalidator> 
 
< br />< br /> 
 
<！ - 当Button2被点击时，只验证
控件是LocationInfoGroup 
的一部分被验证.--> 
< asp：button id =Button2
 text =验证
 causesvalidation =true
 validationgroup =LocationInfoGroup
 runat =Server /> 
  

Is there any way to limit the validation of a validator control to a particular event or trigger? Say, I want my validator1 to be activated only when button1 was clicked, and validator2 to be activated only when button2 was clicked. How can I do this in asp.net?

解决方案

ValidationGroups are what you're looking for(ASP.NET >= 2.0)

Validation groups allow you to organize validation controls on a page as a set. Each validation group can perform validation independently from other validation groups on the page.

<asp:textbox id="AgeTextBox" 
  runat="Server">
</asp:textbox>

&nbsp;

<asp:requiredfieldvalidator id="RequiredFieldValidator1"
  controltovalidate="AgeTextBox"
  validationgroup="PersonalInfoGroup"
  errormessage="Enter your age."
  runat="Server">
</asp:requiredfieldvalidator>

<br /><br />

<!--When Button1 is clicked, only validation
controls that are a part of PersonalInfoGroup
are validated.-->
<asp:button id="Button1" 
  text="Validate" 
  causesvalidation="true"
  validationgroup="PersonalInfoGroup"
  runat="Server" />

<br /><br />

<asp:textbox id="CityTextBox" 
  runat="Server">
</asp:textbox>

&nbsp;

<asp:requiredfieldvalidator id="RequiredFieldValidator2"
  controltovalidate="CityTextBox"
  validationgroup="LocationInfoGroup"
  errormessage="Enter a city name."
  runat="Server">
</asp:requiredfieldvalidator>

<br /><br />

<!--When Button2 is clicked, only validation
controls that are a part of LocationInfoGroup
are validated.-->
<asp:button id="Button2" 
  text="Validate" 
  causesvalidation="true"
  validationgroup="LocationInfoGroup"
  runat="Server" />
