<script language="javascript" type="text/javascript">

        function allcheck()
       {   var e = form1.elements;
            if(document.getElementById("all").checked)//全选处于checked
           {
                for (var i =0;i<e.length;i++)
                 {
                        if(e[i].name =="userid")
                        {
                            e[i].checked = true;
                        }
                 }
          }
          else//全选处于非checked
          {
                for (var i =0;i<e.length;i++)

我以前做的

<table cellpadding="0" cellspacing="1" class="border" align="center" width="99%">
        <tr>
            <td>
             &nbsp;<a href="User.aspx?type=add">新增管理员</a> | <a href="ChangePassword.aspx">修改密码</a>

           <td align="right">
            <script type="text/javascript">
            function SelectAll()
            { 
                  var s = $("tbReport").getElementsByTagName("INPUT")
                    for(var i=0;i<s.length;i++)
                    {
                        if(s[i].type=="checkbox")
                        {
                            s[i].checked=$("cbAll").checked;
                        }
                    }
            }   
           function CheckSelected()
          {
            var s = $("tbReport").getElementsByTagName("INPUT")
            var flag = false; 
            for(var i=0;i<s.length;i++)
            {
                if(s[i].type=="checkbox"&&s[i].checked)
                {
                    flag = true;
                }
            }
           if(!flag) 
          { 
            alert('请选择要删除的管理员信息');
            return false; 
           }
          else
          {
            return confirm('你确定要删除选择的管理员信息吗?');
          }  
          }  
            </script> 
           </td> 
        </tr>
    </table>

楼主给你一个简单的例子：

 protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
        {
            foreach (RepeaterItem item in this.Repeater1.Items)
            {
                CheckBox checkBox = item.FindControl("CheckBox2") as CheckBox;
                checkBox.Checked = (sender as CheckBox).Checked;
            }
        }

<div>
    <table>
        <asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1" 
            onitemcommand="Repeater1_ItemCommand">
        <HeaderTemplate>
        <tr>
             <td>
                 全选<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack=true OnCheckedChanged="CheckBox1_CheckedChanged" />
             </td>
        </tr>
        </HeaderTemplate>
        <ItemTemplate>
              <tr>
                   <td>
                       <asp:CheckBox ID="CheckBox2" runat="server" Text='<%#Eval("City") %>' />
                   </td>
              </tr>
        </ItemTemplate>
        </asp:Repeater>
        </table>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" 
            SelectCommand="SELECT top 10 [City] FROM [Customers]"></asp:SqlDataSource>
    </div>

当然js也是可以实现的。

  抱歉我写的不够明确！
 我的现状是全选已经实现我是用个hidden来把所有页面上的数据放在其内，这是在数据绑定到repeater时同时写入该hidden内。但反选功能我还没能实现。反选我是用for来读取选中的，但只能读取当前页，如果跨页了（点其他页，后页面有刷新的），前面选定的内容就会清空。“选定的清空”，“只能读取当前页选定的数据”是我头疼的。
  忘高人指点1 2！！！
