怎么让一组RadioButton的选择改变,就执行相应的功能,不必每个RadioButton都加一个事件

[lyboy8]

例如:
aspx代码:
<asp:RadioButton ID="RadioButton1" runat="server" GroupName="rb" Text="1"
AutoPostBack="True" oncheckedchanged="RadioButton1_CheckedChanged" />
<br />
<asp:RadioButton ID="RadioButton2" runat="server" GroupName="rb" Text="2"
AutoPostBack="True" oncheckedchanged="RadioButton2_CheckedChanged1"/>
<br />
<asp:RadioButton ID="RadioButton3" runat="server" GroupName="rb" Text="3"
AutoPostBack="True" oncheckedchanged="RadioButton3_CheckedChanged"/>
<br />
<asp:RadioButton ID="RadioButton4" runat="server" GroupName="rb" Text="4"
AutoPostBack="True" oncheckedchanged="RadioButton4_CheckedChanged"/>
<br />
<asp:RadioButton ID="RadioButton5" runat="server" GroupName="rb" Text="5"
AutoPostBack="True" oncheckedchanged="RadioButton5_CheckedChanged"/>
<br />
<asp:Label ID="Label1" runat="server" Text="rb"></asp:Label>
cs代码:
protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
this.Label1.Text = "你选择了1.";
}
protected void RadioButton2_CheckedChanged1(object sender, EventArgs e)
{
this.Label1.Text = "你选择了2.";
}
protected void RadioButton3_CheckedChanged(object sender, EventArgs e)
{
this.Label1.Text = "你选择了3.";
}
protected void RadioButton4_CheckedChanged(object sender, EventArgs e)
{
this.Label1.Text = "你选择了4.";
}
protected void RadioButton5_CheckedChanged(object sender, EventArgs e)
{
this.Label1.Text = "你选择了5.";
}


我想实现的是:这一组RadioButton就对应一个事件,不必要在cs文件里一个RadioButton就一个checkedchange.

现在代码少点还好,有上百个RadioButton,就很麻烦啦.

有什么方法实现呢.

希望高手指点一下,谢谢!!

绑定同一个
protected void RadioButton_CheckedChanged(object sender, EventArgs e)
{
RadioButton rdb=sender as RadioButton;
}
RadioButtonlist

用RadioButtonList,通过索引号来判断

用list版面难看..
具体说一下怎么绑定到同一个..谢谢..

我不单是一组RadioButton而已,,我有好几组,每一组控制一个Label...

[lyboy8]

protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
if (RadioButton1.Checked)
{
Label4.Text = "1";
}
else if (RadioButton2.Checked)
{
Label4.Text = "2";
}
else if (RadioButton3.Checked)
{
Label4.Text = "3";
}
else if (RadioButton4.Checked)
{
Label4.Text = "4";
}
else if (RadioButton5.Checked)
{
Label4.Text = "5";
}
}
谢谢指点,我的实现是这样,不知道还可不可以改进呢...

做人个共公事件出来，多次调用

RadioButtonList，就是一组单选框，正解
