如何限制验证，以一个特定的触发？ [英] How to limit validation to a particular trigger?

问题描述

有没有什么办法的验证控件的验证限制在一个特定的事件或触发？再说了，我要被点击按钮1时才会被激活我的validator1，并点击按钮2时，只激活validator2。我怎样才能做到这在asp.net中？

解决方案

的 你在找什么ValidationGroups（ASP.NET> = 2.0）

  

验证组让你组织一个页面上的验证控件
  为一组。每个验证组可以独立执行验证
  从页面上的其他验证组。

 ＆LT; ASP：文本框的id =AgeTextBox
  =服务器＆GT;
＆LT; / ASP：文本＆GT;＆安培; NBSP;＆LT; ASP：的RequiredFieldValidator ID =RequiredFieldValidator1
  的ControlToValidate =AgeTextBox
  的ValidationGroup =PersonalInfoGroup
  errormessage的=请输入您的年龄。
  =服务器＆GT;
＆LT; / ASP：＆的RequiredFieldValidator GT;＆LT; BR /＆GT;＆LT; BR /＆GT;＆LT;！ - 当Button1的点击，只验证
是PersonalInfoGroup的一部分控制
经过验证.--＆GT;
＆LT; ASP：按钮的ID =Button1的
  文字=验证
  的CausesValidation =真
  的ValidationGroup =PersonalInfoGroup
  =服务器/＆GT;＆LT; BR /＆GT;＆LT; BR /＆GT;＆LT; ASP：文本框的id =CityTextBox
  =服务器＆GT;
＆LT; / ASP：文本＆GT;＆安培; NBSP;＆LT; ASP：的RequiredFieldValidator ID =RequiredFieldValidator2
  的ControlToValidate =CityTextBox
  的ValidationGroup =LocationInfoGroup
  errormessage的=输入城市名称。
  =服务器＆GT;
＆LT; / ASP：＆的RequiredFieldValidator GT;＆LT; BR /＆GT;＆LT; BR /＆GT;＆LT;！ - 当Button2的点击，只验证
是LocationInfoGroup的一部分控制
经过验证.--＆GT;
＆LT; ASP：按钮的ID =Button2的
  文字=验证
  的CausesValidation =真
  的ValidationGroup =LocationInfoGroup
  =服务器/＆GT;
 

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" />
