Grid固定表头和固定栏css实现

.Freezing th{text-overflow:ellipsis;overflow:hidden;white-space: nowrap;padding:2px;}
</style>

<div style="overflow-y: scroll; height: 200px;width:300px" id="dvBody">

<asp:GridView ID="GridView1" runat="server"   ......

.....

                        <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" CssClass="Freezing"/>
                    </asp:GridView>
        </div>

用法：CSS设如上的样式，HeaderStyle加CssClass="Freezing，套住GridView的Div设置高度宽度 <div style="overflow-y: scroll; height: 200px;width:200px" >

另外一种css写法

.fixedheadercell
{
    FONT-WEIGHT: bold;
    FONT-SIZE: 10pt;
    WIDTH: 200px;
    COLOR: white;
   
    BACKGROUND-COLOR: darkblue;
}
 
.fixedheadertable
{
    left: 0px;
    position: relative;
    top: 0px;
    padding-right: 2px;
    padding-left: 2px;
    padding-bottom: 2px;
    padding-top: 2px;
}
 
.gridcell
{
    WIDTH: 200px;
}

用于固定栏的css

.fixedHeaderTr  
    {  
        background-color:whitesmoke;  
        z-index:10;  
        position:relative;  
        top:expression(this.offsetParent.scrollTop);  
}
用css   比较好

固定栏, 我猜是

.Freezing 
   { 
    
   position:relative ;
   table-layout:fixed;
   left:expression(this.offsetParent.scrollLeft);  
   z-index: 10;
   }

.Freezing td{text-overflow:ellipsis;overflow:hidden;white-space: nowrap;padding:2px;}

/* Div container to wrap the datagrid */
div#div-datagrid {
width: 420px;
height: 200px;
overflow: auto;
scrollbar-base-color:#ffeaff;
}

/* Locks the left column */
td.locked, th.locked {
font-size: 7pt;
text-align: left;
background-color:inherit;
font-weight: bold;
position:relative;
cursor: default;
left: expression(document.getElementById("div-datagrid").scrollLeft-2); /*IE5+ only*/
}


/* Locks table header */
th {
font-size: 7pt;
font-weight: bold;
text-align: center;
background-color: navy;
color: white;
font-weight:bold;
height:15pt;
border-right: 1px solid silver;
position:relative;
cursor: default;
top: expression(document.getElementById("div-datagrid").scrollTop-2); /*IE5+ only*/
z-index: 10;
}

/* Keeps the header as the top most item. Important for top left item*/
th.locked {z-index: 99;text-align:center;}


/* DataGrid Item and AlternatingItem Style*/
.GridRow {font-size: 7pt; color: black; font-family: Verdana; background-color:#ffffff; height:15px;}
.GridAltRow {font-size: 7pt; color: black; font-family: Verdana; background-color:#eeeeee; height:15px;}
