Question

我有一个ASP.NET网格视图，它有几个相关的详细信息视图和一个辅助网格视图。当用户单击gridview中的行时，详细信息视图会弹出gridview的右侧。这很好，但随着gridview行的数量增加，详细信息视图在页面上越来越低，这使得用户难以找到并且令人沮丧。

我想要做的是当用户选择他们感兴趣的行时，将详细信息视图的顶部与所选行对齐。

我尝试过设置CSS：

[id$="ContentPlaceHolder1_dvProductionReport"], 
[id$="ContentPlaceHolder1_dvOraclePartDetails"], 
[id$="ContentPlaceHolder1_gvReceipts"] 
{
    position: fixed;
}

这没有用。我还尝试使用this example使用JavaScript定位它（在此示例中仅使用第一个选择器）：

<script type="text/javascript" src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript">
    $().ready(function () {
        //var $scrollingDiv = [id$ = "ContentPlaceHolder1_dvProductionReport"];
        var elements = document.querySelector('[id$="ContentPlaceHolder1_dvProductionReport"]');
        console.log(elements);

        $(window).scroll(function () {
            elements
                .stop()
                .animate({ "marginTop": ($(window).scrollTop() + 30) + "px" }, "slow");
        });
    });
</script>

但是这显然不适用于Chrome，因为它显然是＃34; animate＆＃34;是Chrome中的关键字，但example适用于Firefox。

问题：

如何在用户滚动时将详细信息视图保留在视图中，或者至少弹出与他们所选择的网格视图中的行对齐的详细信息视图？

修改回应@rexroxm的建议：我添加了： <div style="position: absolute"><td>...</td></div>围绕第一个详情视图。这没有任何区别，所以我已将此添加到.CSS文件中：

[id$="ContentPlaceHolder1_dvProductionReport"], 
[id$="ContentPlaceHolder1_dvOraclePartDetails"], 
[id$="ContentPlaceHolder1_gvReceipts"] 
{
    position: absolute;
}

我可以看到position: absolute;的CSS出现在所有三个依赖详细信息视图（2）和gridview（1）上。如果我在Chrome中检查样式＆gt;检查＆gt;开发人员工具，我看到position: absolute;在第一个视图中显示所有三个，但它在第二个视图中排列（不确定这些是什么，但它们会显示CSS的样式）你选择的元素）。我也尝试过使用：

[id$="ContentPlaceHolder1_dvProductionReport"], 
[id$="ContentPlaceHolder1_dvOraclePartDetails"], 
[id$="ContentPlaceHolder1_gvReceipts"] 
{
    position: absolute !important;
}

这也显示为内行。

以下是整个<td>...</td>，对不起，这很长，但可能会有所帮助：

        <td>
        <div style="position: absolute">

Answer 1

您可以将详细信息视图的position:absolute保留在页面/视图中。当有人点击主网格视图中的用户时，您可能会将其数据绑定到辅助网格视图，然后显示它。将position设置为容器absolute的{{1}}中的style会将其保留在视图中。您还可以在div的右上角放置一个十字按钮，其中包含使用事件div/table设置display:none的辅助Gridview。

自动滚动详细信息视图和选定的gridview行
