问题描述

嗨..有谁能帮助我.
我对必填字段验证器有疑问.实际上，我有一份注册表，并且有一些字段，例如(全名，姓氏，d.o.b等).
有一个复选框，当我选中该复选框时，我想要的是我在全名或姓氏可见性上应用的必需验证器将被隐藏.我的意思是行不通.其余所有必需的字段验证器将起作用.请帮助我..

推荐答案

首先检查验证组 ...
在必填字段中检查 Display ="None" .

First check for validation group...
check for Display="None" in required field.

转到复选框的已选中已更改事件，并禁用RequireFieldValidator(确保CheckBox 的AutoPostBack 属性设置为true).试试这个:

Hi,
Go to the checked changed event of your checkbox and disable the RequireFieldValidator(make sure the AutoPostBack property of your CheckBox is set to true). Try this:

protected void checbox1_CheckChanged(object sender, EventArgs e)
{
    if(checkbox1.Checked)
    {
        //Suppose your first name RequiredFieldValidator's id is RequiredFieldValidator1
        //And your last name RequiredFieldValidator's id is RequiredFieldValidator2
        RequiredFieldValidator1.Visible = false;
        RequiredFieldValidator2.Visible = false;
    }
    else
    {
        RequiredFieldValidator1.Visible = false;
        RequiredFieldValidator2.Visible = false;
    }
}

您好

您还可以尝试使用自定义验证程序尝试另一种解决方案(如果要在客户端进行所有操作).在验证功能中，您可以检查是否已选中该复选框，然后根据该检查来检查您的字段.

希望对您有帮助.

Hi

There is another solution you can try (if you want to make this all in client side ) with custom validator. In the validation function you can check if the check box is checked or not and then check your field based on the check.

Please see the link and go to "Custom Validator" Section

Hope this will help you.
