<style>
.Freezing 
   { 
    
   position:relative ;
   table-layout:fixed;
   top:expression(this.offsetParent.scrollTop);  
   z-index: 10;
   }

.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;}
