单选控件radiobutton的属性问题！简单。着急！
我想设置2个单选按钮 ，但是在后台代码里要做判断选了那项。请问用radiobutton的哪个属性？多谢。我是刚学.net 的。大家见谅
------解决方案--------------------
应该使用Checked属性，例如：
void SubmitBtn_Click(Object Sender, EventArgs e) {
if (Radio1.Checked) {
Label1.Text = "You selected " + Radio1.Text;
}
else if (Radio2.Checked) {
Label1.Text = "You selected " + Radio2.Text;
}
else if (Radio3.Checked) {
Label1.Text = "You selected " + Radio3.Text;
}
}
------解决方案--------------------
完整点的MSDN示例如下：
下面的示例演示如何使用 RadioButton 控件为用户提供一组互斥的选项。
<%@ Page Language= "C# " AutoEventWireup= "True " %>
<html>
<head>
<script language= "C# " runat= "server ">
void SubmitBtn_Click(Object Sender, EventArgs e) {
if (Radio1.Checked) {
Label1.Text = "You selected " + Radio1.Text;
}
else if (Radio2.Checked) {
Label1.Text = "You selected " + Radio2.Text;
}
else if (Radio3.Checked) {
Label1.Text = "You selected " + Radio3.Text;
}
}
</script>
</head>
<body>
<h3> RadioButton Example </h3>
<form runat=server>
<h4> Select the type of installation you want to perform: </h4>
<asp:RadioButton id=Radio1 Text= "Typical " Checked= "True " GroupName= "RadioGroup1 " runat= "server " /> <br>
This option installs the features most typically used. <i> Requires 1.2 MB disk space. </i> <p>
<asp:RadioButton id=Radio2 Text= "Compact " GroupName= "RadioGroup1 " runat= "server "/> <br>
This option installs the minimum files required to run the product. <i> Requires 350 KB disk space. </i> <p>
<asp:RadioButton id=Radio3 runat= "server " Text= "Full " GroupName= "RadioGroup1 " /> <br>
This option installs all features for the product. <i> Requires 4.3 MB disk space. </i> <p>
<asp:button text= "Submit " OnClick= "SubmitBtn_Click " runat=server/>
<asp:Label id=Label1 font-bold= "true " runat= "server " />
</form>
</body>
</html>
