关于单选按钮验证 [英] regarding radio button validation

问题描述

我对单选按钮验证存在问题.我想使用当我单击提交"按钮而不选择任何一个单选按钮时发生的验证.就像会有两个单选按钮，其中包含文本(男，女).
当我选择男性时，验证将被隐藏，而当我选择两者都不选择时，验证将可见(验证错误应在标签中).

i have a problem with radiobutton validation . i want to use such a validation that occur when i click on submit button without selecting any one of radiobutton. like there will be two radio button that contains the text like(male, female).
and when i select male the validation would be hide and when i select none of these two then validation will be visible(validation error should be in label).

推荐答案

在单选按钮的GroupName属性中添加相同的名称

Just add the same name in radiobutton GroupName property

使此代码单击按钮单击事件

if(Radiobutton1.checked！= true && Radiobutton2.checked！= true)
{
label1.text =请选择性别";
}

我认为这段代码确实可以帮助您

1.添加GroupName属性，并为两个单选按钮添加相同的值.
例如:GroupName ="Gender"
2.放入所需的字段验证器.

您可以使用RadioButtonList进行相同的操作，如下所示:

< asp:radiobuttonlist runat ="server" id ="radio" xmlns:asp =#unknown">
<％-隐含在单选按钮列表中显示的项目-％>
< asp:listitem value ="0"> Male
< asp:listitem value ="1">女性

<％-创建RequiredFieldValidator控件以验证我们创建的RadioButtonList-％>


< asp:requiredfieldvalidator runat ="server" id ="radRfv" controltovalidate ="radio" initialvalue ="0" errormessage =选择一个选项" xmlns:asp =#unknown">

希望对您有帮助

1. Add GroupName attribute and put same value for both the radio buttons.
for example: GroupName="Gender"
2. Put required field validator.

You can do the same using RadioButtonList as follows:

<asp:radiobuttonlist runat="server" id="radio" xmlns:asp="#unknown">
<%--Creaint Items to be display in Radio Button List--%>
<asp:listitem value="0">Male
<asp:listitem value="1">Female

<%--Creating RequiredFieldValidator control to validate RadioButtonList that we have created--%>


<asp:requiredfieldvalidator runat="server" id="radRfv" controltovalidate="radio" initialvalue="0" errormessage="Select one option" xmlns:asp="#unknown">

Hope this will help you
