问题描述

我有多个ValidationSummary来验证我的单选按钮。如何只用一个按钮来调用我的验证？



我不能在我的网站上使用RadioButtonList。但我需要验证我的单选按钮。我也不能默认选中我的一个单选按钮。



所以我的困境是弄清楚如何只用一个按钮验证我的单选按钮组。我正在使用ASP.NET和C＃



提前谢谢



我有什么试过：



< asp：ValidationSummary ID =ValidationSummary1ValidationGroup =sample1DisplayMode =Listrunat =serverForeColor =红色Font-Bold =false/>

< asp：RadioButton ID =RadioBtn1runat =serverValidationGroup =sample1GroupName =rpt1Text =One />

< asp：RadioButton ID =RadioBtn2runat =serverValidationGroup =sample1GroupName =rpt1Text =Two/>



< asp：ValidationSummary ID =ValidationSummary2ValidationGroup =sample2DisplayMode =Listrunat =serverForeColor =RedFont-Bold =false/>

< asp：RadioButton ID =RadioBtn3runat =serverValidationGroup =sample2GroupName =rpt2Text =Three/>

< ; asp：RadioButton ID =RadioBtn4runat =serverValidationGroup =sample2Group Name =rpt2Text =Four/>







< asp：CustomValidator ID =CustomValidator1runat =serverValidationGroup =sample1

ErrorMessage =请选择其中一个单选按钮

OnServerValidate =ValidateSample/>



< asp：CustomValidator ID =CustomValidator2runat =serverValidationGroup =sample2

ErrorMessage =请选择一个单选按钮

OnServerValidate =ValidateSample/>



< asp：按钮ID =Button1runat =服务器ValidationGroup =sample1Text =Submit/>

< asp：按钮ID =Button2runat =serverValidationGroup =sample2Text =Submit/> ;







protected void ValidateSample（对象源，ServerValidateEventArgs ar gs）

{

if（（RadioBtn1.Checked）|| （RadioBtn2.Checked）|| （RadioBtn3.Checked）|| （RadioBtn4.Checked））

{

args.IsValid = true;

}

else

{

args.IsValid = false;

}

}

解决方案

验证组旨在为不同的按钮提供不同的验证集。如果您希望在单击一个按钮时触发所有验证器，则要么不设置验证组，要么将它们全部设置为相同的值。



验证摘要用于显示表单上所有验证错误的摘要。它并不意味着显示单个控件的验证错误。使用验证器控件来执行此操作。

 <   asp：CustomValidator     runat   =  server    ForeColor   = 红色   字体粗体  =  false   显示  = 动态   文字  = 请选择其中一个单选按钮    OnServerValidate   =  ValidateSample1     /  >  
 <   asp：RadioButton     ID   =  RadioBtn1    runat   =  server    ValidationGroup   =  sample1    GroupName   =  rpt1   文字  = 一个    /  >  
 <   asp：RadioButton     ID   =  RadioBtn2    runat   =  server    ValidationGroup   =  sample1    GroupName   =  rpt1   文本  = 两个    /  >  
 
 <   asp：CustomValidator     runat   =  server    ForeColor   = 红色   字体粗体  =  false   显示  = 动态   文字  = 请选择其中一个单选按钮    OnServerValidate   =  ValidateSample2    /  >  
 <   asp：RadioButton     ID   = < span class =code-keyword> RadioBtn3    runat   =  server    ValidationGroup   =  sample2    GroupName   =  rpt2   文字  = 三    /  >  
 <   asp：RadioButton     ID   =  RadioBtn4    runat   =  server    ValidationGroup   =  sample2    GroupName   =   rpt2   文字 < span class =code-keyword> = 四    /  >  

  protected   void  ValidateSample1（ object  sender，ServerValidateEventArgs e）
 {
 args.IsValid = RadioBtn1.Checked || RadioBtn2.Checked; 
} 
 
 受保护  void  ValidateSample2（ object  sender，ServerValidateEventArgs e）
 {
 args.IsValid = RadioBtn3.Checked || RadioBtn4.Checked; 
} 

现在，帮自己一个忙，给控件带来有意义的ID，而不是接受Visual Studio提供的默认值。您可能还记得 RadioBtn42 意味着现在，但是当你在六个月后回到你的代码时，你会诅咒写作的人它<！/ BLOCKQUOTE>

I have multiple ValidationSummary to validate my radio buttons. How can I use just 1 button to call my Validation?

I can NOT use RadioButtonList on my site. But I need to validate my radio buttons. I also can NOT have 1 of my radio buttons checked by default.

So my dilemma is to figure out how to validate my groups of radio buttons with only 1 button. I'm using ASP.NET and C#

Thanks in advance

What I have tried:

<asp:ValidationSummary ID="ValidationSummary1" ValidationGroup="sample1" DisplayMode="List" runat="server" ForeColor="Red" Font-Bold="false" />
<asp:RadioButton ID="RadioBtn1" runat="server" ValidationGroup="sample1" GroupName="rpt1" Text="One" />
<asp:RadioButton ID="RadioBtn2" runat="server" ValidationGroup="sample1" GroupName="rpt1" Text="Two" />

<asp:ValidationSummary ID="ValidationSummary2" ValidationGroup="sample2" DisplayMode="List" runat="server" ForeColor="Red" Font-Bold="false" />
<asp:RadioButton ID="RadioBtn3" runat="server" ValidationGroup="sample2" GroupName="rpt2" Text="Three" />
<asp:RadioButton ID="RadioBtn4" runat="server" ValidationGroup="sample2" GroupName="rpt2" Text="Four" />



<asp:CustomValidator ID="CustomValidator1" runat="server" ValidationGroup="sample1"
ErrorMessage="Please select one of the radio button"
OnServerValidate="ValidateSample" />

<asp:CustomValidator ID="CustomValidator2" runat="server" ValidationGroup="sample2"
ErrorMessage="Please select one of the radio button"
OnServerValidate="ValidateSample" />

<asp:Button ID="Button1" runat="server" ValidationGroup="sample1" Text="Submit" />
<asp:Button ID="Button2" runat="server" ValidationGroup="sample2" Text="Submit" />



protected void ValidateSample(object source, ServerValidateEventArgs args)
{
if ((RadioBtn1.Checked) || (RadioBtn2.Checked) || (RadioBtn3.Checked) || (RadioBtn4.Checked))
{
args.IsValid = true;
}
else
{
args.IsValid = false;
}
}

解决方案

Validation groups are intended to provide different sets of validation for different buttons. If you want all of the validators to fire when you click one button, then either don't set the validation groups, or set them all to the same value.

The validation summary is used to display a summary of all validation error on the form. It is not meant to display the validation errors for a single control. Use the validator control to do that.

<asp:CustomValidator runat="server" ForeColor="Red" Font-Bold="false" Display="Dynamic" Text="Please select one of the radio buttons" OnServerValidate="ValidateSample1" />
<asp:RadioButton ID="RadioBtn1" runat="server" ValidationGroup="sample1" GroupName="rpt1" Text="One" />
<asp:RadioButton ID="RadioBtn2" runat="server" ValidationGroup="sample1" GroupName="rpt1" Text="Two" />

<asp:CustomValidator runat="server" ForeColor="Red" Font-Bold="false" Display="Dynamic" Text="Please select one of the radio buttons" OnServerValidate="ValidateSample2" />
<asp:RadioButton ID="RadioBtn3" runat="server" ValidationGroup="sample2" GroupName="rpt2" Text="Three" />
<asp:RadioButton ID="RadioBtn4" runat="server" ValidationGroup="sample2" GroupName="rpt2" Text="Four" />

protected void ValidateSample1(object sender, ServerValidateEventArgs e)
{
    args.IsValid = RadioBtn1.Checked || RadioBtn2.Checked;
}

protected void ValidateSample2(object sender, ServerValidateEventArgs e)
{
    args.IsValid = RadioBtn3.Checked || RadioBtn4.Checked;
}

Now, do yourself a favour and give your controls meaningful IDs, rather than accepting the defaults provided by Visual Studio. You might remember what RadioBtn42 means now, but when you come back to your code in six months time, you'll be cursing the person who wrote it!
