javascript 中checkbox的onclick事件大概：
document.getElementById("checkbox2"/*2-4*/).checked = ! document.getElementById("checkbox1).checked ;其它雷同
把checkbox的autopostback设为true,当点击的时侯就在提交到后台，在C#里做处理就行了！
朋友..你CheckBox的属性AutoPostBack="True"要改成这个.不知道你改了没有..
public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {    }
    protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox2.Checked = false;
        CheckBox3.Checked = false;
        CheckBox4.Checked = false;
    }
    protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox1.Checked = false;
    }
    protected void CheckBox3_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox1.Checked = false;
    }
    protected void CheckBox4_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox1.Checked = false;
    }
}

这样的小问题,在前台用Javascript实现是正道!<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %><html>
<head runat="server">
    <title>无标题页</title>
</head>
<script>
function Change1(){
    document.getElementById("CheckBox2").checked=false;
    document.getElementById("CheckBox3").checked=false;
    document.getElementById("CheckBox4").checked=false;
}
function Change2(){
    document.getElementById("CheckBox1").checked=false;
}
</script>
<body>
    <form id="form1" runat="server">
        <asp:CheckBox ID="CheckBox1" onclick="Change1()" runat="server" />
        <asp:CheckBox ID="CheckBox2" onclick="Change2()" runat="server" />
        <asp:CheckBox ID="CheckBox3" onclick="Change2()" runat="server" />
        <asp:CheckBox ID="CheckBox4" onclick="Change2()" runat="server" />
    </form>
</body>
</html>
1.
客户端方法
<script>
function Change1(sender){
    if(sender.checked) {
    document.getElementById("CheckBox2").checked=false;
    document.getElementById("CheckBox3").checked=false;
    document.getElementById("CheckBox4").checked=false;
    }
}
function Change2(sender){
    if(sender.checked){
    document.getElementById("CheckBox1").checked=false;
    }
}
</script><asp:CheckBox ID="CheckBox1" onclick="Change1(this)" runat="server" />
        <asp:CheckBox ID="CheckBox2" onclick="Change2(this)" runat="server" />
        <asp:CheckBox ID="CheckBox3" onclick="Change2(this)" runat="server" />
        <asp:CheckBox ID="CheckBox4" onclick="Change2(this)" runat="server" />2.
服务器端方法
// .aspx
<asp:checkbox id=CheckBox1 autopostback=true
oncheckedchanged=CheckBox1_CheckedChanged runate=server/>
<asp:checkbox id=CheckBox2 autopostback=true oncheckedchanged=CheckBox234_CheckedChanged runate=server/>
<asp:checkbox id=CheckBox3 autopostback=true oncheckedchanged=CheckBox234_CheckedChanged runate=server/>
<asp:checkbox id=CheckBox4 autopostback=true oncheckedchanged=CheckBox234_CheckedChanged runate=server/>
// .aspx.cs
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
    {
        if(CheckBox1.Checked) {
            CheckBox2.Checked = false;
            CheckBox3.Checked = false;
            CheckBox4.Checked = false;
        }
    }
    protected void CheckBox234_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox chk = sender as CheckBox;
        if(chk.Checked) {
            CheckBox1.Checked = false;
        }
    }
用前台就可以了
方法如  Jialang(疯狂键盘)  所写
逻辑不用帮忙吧
