根据分辨率调整div的height
<div   id=divDd   style= "overflow:auto;   height:520px;   width:100%; ">
        <asp:DataGrid   ID= "DataGrid1 "   runat= "server ">
        </asp:DataGrid>
        </div>
       
        <script   language=javascript>
        var   x   =   screen.width;
        var   y   =   screen.height;    
        if((screen.width+ "* "+screen.height)   ==   "1280*1024 ")
        {
                document.getElementById( "divDd ").style.height   =   620px;
        }
        else
        {
                document.getElementById( "divDd ").style.height   =   520px;
        }
        </script>
