滚动时修复gridview标题

【中文标题】滚动时修复gridview标题【英文标题】:fixing gridview header while scrolling 【发布时间】:2013-08-02 03:53:46 【问题描述】:我已经修复了 GridView 标题,当我向下滚动标题时,标题将保持不变,但问题是标题格式不正确。就像所有列标题都被缩小并且不会显示在特定列下。我尝试了很多东西,但没有任何用处。显然,标题宽度不等于列。我使用 javascript 代码进行滚动,也使用 CssClass 进行修复。
请为我找到解决方案
JavaScript 代码
<script type = "text/javascript">
var GridId = "<%=GridViewLeaveHistory.ClientID %>";
var ScrollHeight = 300;
var ScrollWidth = 300;
window.onload = function ()
var grid = document.getElementById(GridId);
var gridWidth = grid.offsetWidth;
var gridHeight = grid.offsetHeight;
var headerCellWidths = new Array();
for (var i = 0; i < grid.getElementsByTagName("TH").length; i++)
headerCellWidths[i] = grid.getElementsByTagName("TH")[i].offsetWidth;
grid.parentNode.appendChild(document.createElement("div"));
var parentDiv = grid.parentNode;
var table = document.createElement("table");
for (i = 0; i < grid.attributes.length; i++)
if (grid.attributes[i].specified && grid.attributes[i].name != "id")
table.setAttribute(grid.attributes[i].name, grid.attributes[i].value);
table.style.cssText = grid.style.cssText;
table.style.width = gridWidth + "px";
table.appendChild(document.createElement("tbody"));
table.getElementsByTagName("tbody")[0].appendChild(grid.getElementsByTagName("TR")[0]);
var cells = table.getElementsByTagName("TH");
var gridRow = grid.getElementsByTagName("TR")[0];
for (var i = 0; i < cells.length; i++)
var width;
if (headerCellWidths[i] > gridRow.getElementsByTagName("TD")[i].offsetWidth)
width = headerCellWidths[i];
else
width = gridRow.getElementsByTagName("TD")[i].offsetWidth;
cells[i].style.width = parseInt(width - 3) + "px";
gridRow.getElementsByTagName("TD")[i].style.width = parseInt(width - 3) + "px";
parentDiv.removeChild(grid);
var dummyHeader = document.createElement("div");
dummyHeader.appendChild(table);
parentDiv.appendChild(dummyHeader);
var scrollableDiv = document.createElement("div");
if (parseInt(gridHeight) > ScrollHeight)
gridWidth = parseInt(gridWidth) + 17;
scrollableDiv.style.cssText = "overflow:auto;height:" + ScrollHeight + "px;width:" + gridWidth + "px" + ScrollWidth;
scrollableDiv.appendChild(grid);
parentDiv.appendChild(scrollableDiv);
Css 类
.Freezing
position: relative;
top: expression(this.offsetParent.scrollTop-1);
z-index: 10;
GridView 代码
<div style="width: 810px; height: 259px;">
<asp:GridView ID="GridViewLeaveHistory" runat="server" AllowSorting="True"
AutoGenerateColumns="False" BackColor="White" BorderColor="#0061C1"
BorderStyle="None" CaptionAlign="Bottom" EmptyDataText="No Records Found"
Font-Names="Verdana" Font-Size="X-Small" ForeColor="#0061C1" Height="18px"
OnRowCommand="GridViewLeaveHistory_RowCommand"
OnRowDataBound="GridViewLeaveHistory_RowDataBound" CssClass="Freezing"
OnSelectedIndexChanged="GridViewLeaveHistory_SelectedIndexChanged"
ShowFooter="True" ShowHeaderWhenEmpty="True" >

【参考方案1】: <!-- Fixed Grid header Script-->
<script type="text/javascript">
$(document).ready(function ()
var gridHeader = $('#<%=GrdMWRFinal.ClientID%>').clone(true); // Here Clone Copy of Gridview with style
$(gridHeader).find("tr:gt(0)").remove(); // Here remove all rows except first row (header row)
$('#<%=GrdMWRFinal.ClientID%> tr th').each(function (i)
// Here Set Width of each th from gridview to new table(clone table) th
$("th:nth-child(" + (i + 1) + ")", gridHeader).css('width', ($(this).width()).toString() + "px");
);
$("#GHead1").append(gridHeader);
$('#GHead1').css('position', 'top');
$('#GHead1').css('top', $('#<%=GrdMWRFinal.ClientID%>').offset().top);
);
</script>
<!-- Fixed Grid header Script-->
<div id="divGridViewScroll1" style="height: 500px; overflow: scroll">
<div class="table-responsive">
<asp:GridView ID="grdEmpValidations" runat="server" CssClass="table table-small-font table-bordered table-striped">
