Question

我正在尝试将选定的单选按钮值从html到服务器端，以便我可以将它们保存在数据库中我已经在php中做了类似的操作，不知道如何在asp.net / C＃

<form runat="server" id='attendence_form' >
<table id="attendence_div" width="100%" align="center" cellpadding="2" cellspacing="2" border="0">
    <tr align="left" style="background-color:#004080;color:White;">
        <td>Student Name</td>                        
        <td>Present</td>            
        <td>Absent</td>       
        <td>Leave</td>                    
    </tr>
    <tr>
        <td>ANITHA S</td>
        <td><input type="radio" name="Present0" value="Present"></td>
        <td><input type="radio" name="Present0" value="Absent"></td>
        <td><input type="radio" name="Present0" value="Leave"></td>
    </tr>
    <tr>
        <td>ANITHA T C</td>
        <td><input type="radio" name="Present1" value="Present"></td>
        <td><input type="radio" name="Present1" value="Absent"></td>
        <td><input type="radio" name="Present1" value="Leave"></td>
    </tr>
    <tr>
        <td>BINDU K V</td>
        <td><input type="radio" name="Present2" value="Present"></td>
        <td><input type="radio" name="Present2" value="Absent"></td>
        <td><input type="radio" name="Present2" value="Leave"></td>
    </tr>
</table>

听到的是php代码，它通过ajax从用户端获取html表单值并插入我想在asp.net中使用相同的

$conn = new mysqli($servername, $username, $password, $dbname);
    // ** insert data in to data base ** //
    $sql = "INSERT INTO attendance_master (AttendanceDate) VALUES ";
    // **hear the data or is calculated using student as a string the number of student names are passed the same number of data is inserted in to data base ** //
    foreach($_GET['student']  as $i=>$student) {

        // ** so the data is inserted in to data base   ** //
        $sql .= sprintf("%s ('%s')"
        , ($i==0 ? '' : ',')  
        // **  data from Ajax   ** //       
        , mysqli_real_escape_string($conn, trim($_GET['present'][$i]))

        );
    }
    // ** on success full function   ** //
    if ($conn->query($sql)) {
        // **can do any thing to recognise if the data is inserted if this gives the out put then the data is shorly inserted in to data base  ** //
    }

Answer 1

如果是webforms项目，您应该使用

<asp:RadioButton id="someId" runat="server">

更新

要处理单击radiobutton的时间，您需要处理CheckedChanged事件。

someId.CheckedChanged += event_CheckedChanged;

private void event_CheckedChanged(Object sender, EventArgs e) 
{
    ... do stuff...
}

Answer 2

您可以尝试使用<asp: RadioButton id="" runat="server" >。

在服务器端，您可以像这样检查“已检查”属性

if(radioBtn.Checked==true) {}

在数据库中保存表单数据
