固定了 asp.net 滚动时列表视图中的标题

本文关键字：视图 列表 标题 滚动 asp net | 更新日期: 2023-09-27 18:32:37

当我向列表视图添加新行时，最高高度为200px，之后它将滚动，而滚动标题也在滚动.如何修复此标题应该是恒定的 

<asp:ListView ID="listview1" runat="server">
        <LayoutTemplate>

固定了 asp.net 滚动时列表视图中的标题

您可以尝试将标题与内容分开，并将标题放在可滚动内容之外。

<div>Some Page Content </div>
    //your heading goes here
    <div style="max-height: 200px; overflow: auto;">
       //your listview goes here
    </div>
<div>Some Page Content </div>
