问题描述

我正在办理登记表格。首先我尝试使用RequiredfieldValidators，但后来我的CustomValidators不起作用。即使不需要触发RequiredFieldValidators也不行。所以我决定使用所有CustomValidators。服务器端。如果每次验证都成功，那么计数器将会增加。我打算根据计数器的值更改按钮单击事件。现在按钮点击事件没有做任何工作，因为如果它，那么页面被重定向而不触发验证！但现在问题是即使我没有将文本框保持为空或具有默认值，验证也会失败。请帮忙。任何帮助表示赞赏。请原谅这是一个非常愚蠢的问题。我是初学者...



我的aspx页面：



I am working on a registration form. First I tried using RequiredfieldValidators but then my CustomValidators were just not working. Not even if the RequiredFieldValidators didn't need to be fired. So I decided to use all CustomValidators. server side. If each validation is succesful then a counter will increase. I plan to change the button click event based on the value of counter. Now button click event is not doing any work because if it does, then the page is being redirected without firing validations!!! But now the problem is the validation is failing even if I don't keep my textbox empty or having default values. Please help. Any help is appreciated. Please excuse if this is a very stupid question. I am a beginner...
