单选按钮故障... [英] trouble in radio button...

问题描述

我创建了4个单选按钮..

 <   div     class   =  reg-child >  
 <   div     class   =  reg-child-text > 正文类型：<   / div  >  
 <   div     class   =  red-chil d-input    id   =  change_basic_bodytype >  
 < ;  输入    type  < span class =code-keyword> =  radio      value   = 超薄      runat  < span class =code-keyword> =  server   名称  = 正文类型    id   =  rado_slim    /  >  <   label       =  rado_slim   >  Slim <   / label  >  
 <  输入    type   =  radio      value   = 平均值    runat   =   server    name  < span class =code-keyword> = 正文类型    id   =  rado_average    /  >  <   label     for   =  rado_average   > 平均<   /标签 >  
 <  输入   类型  =  radio     值  = 运动    runat   =  server    name   = 正文类型    id   =  rado_athletic   < span class =code-keyword> /  >  <  标签      =  rado_athletic   >  Athletic <   / label  >  
 <  输入    type   =  radio     值  = 重    runat   =  server   名称  = 正文类型    id   =  rado_heavy    /  >  <   label  < span class =code-attribute>   for   =  rado_heavy   > 重<   / label  >  
 <   / div  >  
 <   / div  >  

当我选择上面的值并单击提交按钮时，特定值传递到其他文本框中...这个条件成功运行..当我单击提交按钮而不选择radiobutton..a未定义值保存在数据库中旧数据自动删除和该位置未定义..可以解决此问题

解决方案

试试这个代码...



这个aspx代码

 <   asp：radiobuttonlist     id   =  rbtn_option    runat   =  server    xmlns：asp   = ＃unknown >  
 RepeatDirection = 水平 > 
 <   asp：listitem  >  item1 <   / asp：listitem  >  
 <   asp：listitem  >  item2 <   / asp：listitem  >  
 <   asp：listitem  >  item3 <   / asp：listitem  >  
 <   asp：listitem  < span class =code-keyword>>  item4 <   / asp：listitem  >  
 <   / asp：radiobuttonlist  >  
 
 <   asp：textbox     id   =  txt_val    runat   =  server    xmlns：asp   =  ＃unknown >  <   / asp：textbox  >  
 < span class =code-keyword><   asp：button     id   =  btn_submit    runat   =  server     onclick   = < span class =code-keyword> btn_submit_Click    xmlns：asp   = ＃unknown >  
 Text =提交/> 
 <   / asp：button  >  

这个后面的代码

  protected   void  btn_submit_Click（ object  sender，EventArgs e）
 {
  if （rbtn_option.SelectedIndex <   0 ）
  return ; 
 
 txt_val.Text = rbtn_option.SelectedValue; 
} 
 

我希望它会对你有所帮助。，br />


谢谢你，上帝保佑..

提交时，检查是否选择了Radio Buttons。如果选中，则读取值并保存到数据库，否则不保存。



我确定，您没有检查这个并直接保存该值。 / blockquote>

<div class="reg-child">
  <div class="reg-child-text">Body type :</div>
    <div class="red-child-input" id="change_basic_bodytype">
     <input type="radio"  value="Slim"  runat="server" name="Body type" id="rado_slim" /><label for="rado_slim" >Slim</label>
     <input type="radio"  value="Average" runat="server" name="Body type" id="rado_average" /><label for="rado_average" >Average</label>
      <input type="radio"  value="Athletic" runat="server" name="Body type" id="rado_athletic" /><label for="rado_athletic" >Athletic</label>
         <input type="radio"  value="Heavy" runat="server" name="Body type" id="rado_heavy" /><label for="rado_heavy" >Heavy</label>
    </div>
 </div>

when i select the above value and click submit button,the particular value passed into other textbox..this condition is successfully working..when i click the submit button without selecting a radiobutton..a "undefined" value saved in database the old data automatically deleted and that position "undefined" ..can u solve this problem

解决方案

Try this code...

this the aspx code

    <asp:radiobuttonlist id="rbtn_option" runat="server" xmlns:asp="#unknown">
        RepeatDirection="Horizontal">
        <asp:listitem>item1</asp:listitem>
        <asp:listitem>item2</asp:listitem>
        <asp:listitem>item3</asp:listitem>
        <asp:listitem>item4</asp:listitem>
    </asp:radiobuttonlist>

    <asp:textbox id="txt_val" runat="server" xmlns:asp="#unknown"></asp:textbox>
    <asp:button id="btn_submit" runat="server" onclick="btn_submit_Click" xmlns:asp="#unknown">
        Text="Submit" />
</asp:button>

this the behind code

protected void btn_submit_Click(object sender, EventArgs e)
{
    if (rbtn_option.SelectedIndex < 0)
        return;

    txt_val.Text = rbtn_option.SelectedValue;
}

I hope it will help you.,

thank you and God bless..

While submitting, check if Radio Buttons are selected or not. If selected, then read the value and save to database, else don't save.

I am sure, you are not checking this and directly saving the value.

Hi rajeeshmenoth,
