推荐答案
有一种解决方案可能会对您有所帮助
在每5个表格上添加以下属性
There is a solution which might help you
On every 5 table add the below property
onclick="MakeSelected(this)">
以下是
的实现
Below is the implementation of the
<script language="javascript" type="text/javascript">
function MakeSelected(ctrl) {
document.getElementById(''<%= hdnVal.ClientID%>'').value = ctrl.id;
}
</script
我在页面上创建了一个名为"hdnVal"的隐藏控件，以便我们可以保留所选表的ID.
现在在< form>结束之前标签只需添加以下代码
I created a hidden control on the page with the name "hdnVal" so that we can preserve the ID of the selected table.
Now before end of the <form> tag just add below code
<script language="javascript" type="text/javascript">
if (document.getElementById(''<%= hdnVal.ClientID%>'') != null && document.getElementById(''<%= hdnVal.ClientID%>'').value != "")
document.getElementById(document.getElementById(''<%= hdnVal.ClientID%>'').value).focus();
</script>
所以你的代码看起来像那样
SO your code would look like that
<head runat="server">
<script language="javascript" type="text/javascript">
function MakeSelected(ctrl) {
document.getElementById(''<%= hdnVal.ClientID%>'').value = ctrl.id;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="hidden" runat="server" id="hdnVal" />
<table width="600" cellpadding="0" cellspacing="0" id="table1" onclick="MakeSelected(this)">
<tr>
<td>
</td>
</tr>
</table>
</div>
<script language="javascript" type="text/javascript">
if (document.getElementById(''<%= hdnVal.ClientID%>'') != null && document.getElementById(''<%= hdnVal.ClientID%>'').value != "")
document.getElementById(document.getElementById(''<%= hdnVal.ClientID%>'').value).focus();
</script>
</form>
</body>
您可以尝试-将当前关注的单元格另存为会话变量，如果该会话变量不是null，请将焦点重新设置为该变量.我不知道它是否行得通，但是，好吧，你知道...
You could try this - save the currently focused cell as a session variable, and if that session variab;le isn''t null, set focus back to it. I don''t know if it would work, but, well, you know...
我想你想在回发后仍保持滚动位置
为此，请使用ajax更新面板，并在源代码中写入以下代码
<％@页面标题=" Language ="C#" MasterPageFile =〜/StudentHome.master" MaintainScrollPositionOnPostback ="true" AutoEventWireup ="true" CodeFile ="LessonView.aspx.cs"继承="Student_LessonView"％>
i think you want to remain scroll position still after postback
for that use ajax update panel and write the below code in your source code
<%@ Page Title="" Language="C#" MasterPageFile="~/StudentHome.master" MaintainScrollPositionOnPostback="true" AutoEventWireup="true" CodeFile="LessonView.aspx.cs" Inherits="Student_LessonView"%>
