选择性验证? [英] Selective validation?

问题描述

我正在开发一个显示新闻通讯的Webform.在新闻通讯的底部，有一个注释文本框，允许用户发表评论.我在评论框上附加了RequiredFieldValidator，以防止发布空评论.

一切正常，但我尝试添加注册"功能，以便用户可以在其收件箱中注册其电子邮件地址以接收新闻.
注册"功能包括:
* txtEmailAddress，
* txtEmailAddress
的RequiredFieldValidator * btnSignUp
现在，当单击btnSignUp时，txtComments的RequiredFieldValidator将不允许页面回发！

我知道一个简单的解决方案是将用户重定向到另一个页面进行注册，并将btnSignUp属性设置为:CauseValidation为false.我想我太牛逼了，但我想让用户快速访问新闻页面上的注册！谢谢，除了

I''m developing a Webform that displays a newsletter. At the bottom the newsletter, there is a comment textbox to allow the user to post a comment. I have a RequiredFieldValidator attached to the comment box to prevent empty comments from being posted.

All is working fine but I''m trying to add a "Sign Up" function so the user can register their e-mail address to receive the newsletter in their inbox.
The "Sign Up" functionality consists of:
* txtEmailAddress,
* RequiredFieldValidator for txtEmailAddress
* btnSignUp
Now when btnSignUp is clicked, the RequiredFieldValidator for txtComments will not allow the page to postback!

I know an easy solution would be to redirect the user to another page for registering and set btnSignUp property: CauseValidation to false. I guess I''m too bull headed but I want to give the user the quick access of signing up on the newsletter page! Is there any way besides a lot of javascript to accomplish this?

Thanks,
Richard

推荐答案

设置验证组，以便注册字段不会触发对注释字段的验证

You can set the validation group so the signup fields don''t trigger the validation for the comment field

您需要为其创建ValidationGroup . txtEmailAddress，txtEmailAddress和btnSignUp的RequiredFieldValidator应该在同一验证组下. :-D

You need to create the ValidationGroup for it. RequiredFieldValidator for txtEmailAddress , txtEmailAddress and btnSignUp should be under same validation group. :-D
