固定头网格视图ASP.NET

问题描述

我通过大量的固定头部网格视图的例子走了，并试图采用div和Java脚本的几个选项。一个我因此未从工作的例子，有什么我错过这里。

  CSS
.gridViewHeader
{
     背景色：海军;
    颜色：蓝色;
    字体大小：12像素;
    字体重量：大胆的;
    位置：相对;
    的z-index：10;
   顶部：前pression（小于（％）= gv.HeaderRow％GT; .offsetParent.scrollTop-2）;
}设计源
＆LT;表＆gt;
＆所述; TR＆GT;
            ＆所述; TD＆GT;
                ＆安培; NBSP;
            ＆LT; / TD＆GT;
        ＆LT; / TR＆GT;
    ＆LT; /表＆gt;
    ＆LT; D​​IV＆GT;
        ＆LT; ASP：GridView控件ID =GV=服务器的cellpadding =4每页=50RowHeaderColumn =真

            ＆LT; SelectedRowStyle背景色=＃009999FONT-粗体=真前景色=＃CCFF99/＆GT;
        ＆LT; / ASP：GridView的＆GT;
    ＆LT; / DIV＆GT;
        ＆LT; ASP：HiddenField ID =hiddenfield1=服务器/＆GT;
    ＆LT; / ASP：内容＆GT;
 

解决方案

这的CSS将解决您的问题：

  .GVFixedHeader {字体重量：大胆的;背景颜色：绿色;位置：相对;
             顶部：前pression（this.parentNode.parentNode.parentNode.scrollTop-1）;}
 

I gone through lots of examples for fixed header grid view, and tried few options using div and java scripts. the one i didnot work from the example, is there anything i miss here.

 CSS 
.gridViewHeader
{
     background-color:Navy;
    color:blue;
    font-size:12px;
    font-weight:bold;
    position:relative;
    z-index:10;
   top:expression(<%= gv.HeaderRow %>.offsetParent.scrollTop-2);
}

design source
<table>
<tr>
            <td>
                &nbsp;
            </td>
        </tr>
    </table>
    <div>
        <asp:GridView ID="gv" runat="server" CellPadding="4" PageSize="50" RowHeaderColumn="True"
            AllowPaging="True" BackColor="White" BorderColor="#3366CC" BorderStyle="None"
            BorderWidth="1px" CssClass="gridViewHeader">
            <PagerSettings Mode="NumericFirstLast" />
            <PagerStyle BackColor="#99CCCC" ForeColor="#003399" HorizontalAlign="Left" VerticalAlign="Middle" />
            <RowStyle BackColor="White" ForeColor="#003399" BorderStyle="Inset" HorizontalAlign="Center"
                VerticalAlign="Middle" Wrap="False" />
            <SelectedRowStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" />
        </asp:GridView>
    </div>
        <asp:HiddenField ID="hiddenfield1" runat="server"  />
    </asp:Content>

解决方案

This CSS will fix your problem:

.GVFixedHeader { font-weight:bold; background-color: Green; position:relative; 
             top:expression(this.parentNode.parentNode.parentNode.scrollTop-1);}
