解释到前台的html后成了：
        

<table cellspacing="0" rules="all" border="1" id="myDataGrid" style="height:100%;width:100%;border-collapse:collapse;">
    <tr class="list_1">
        <td class="disTd">&nbsp;</td>
            <td class="list_1" align="Center">选择<input type='checkbox' id='' onclick='doSelectAll();' title='全选'></td>
            <td class="list_1" align="Center">颜色名称</td>
            <td class="list_1" align="Center">颜色HTML编码</td>
    </tr>
<tr class="list_lan">
        <td class="disTd">16</td>
            <td class="list_td" align="Center"> <input id="myDataGrid__ctl2_CheckBox1" type="checkbox" name="myDataGrid:_ctl2:CheckBox1" /></td>
            <td class="list_td" align="Center"><a href="InfoCOLOR.aspx?id=16&amp;flag=0">213`</a></td>
            <td class="list_td" align="Center">123123</td>
    </tr>
</table>
         我们可以看到DataGrid 控件变成了Table标签，id不变，而原来的

<asp:CheckBox id="CheckBox1" runat="server"></asp:CheckBox>
变成了
