Question

这样的感觉应该很容易，但在环顾四周，我寻求一些帮助！我有一个Web Forms应用程序，我从AJAX Control Toolkit（v16.1）创建了一个手风琴。我的代码后面从输入文件夹中获取文件列表，然后遍历它们。有适当的排序逻辑，但要点是这些文件中的每一个都有6个预定义的折叠窗格标题中的适当位置。内容旨在容纳尽可能多的可点击按钮，以满足我的排序逻辑。单击任何按钮时，将调用我的DB上下文的get（）方法以填充附近面板中的GridView。您可以考虑Microsoft Outlook，例如。电子邮件按日期排序，可单独点击，在附近的视图中呈现。

我的问题是这些文件目前在手风琴窗格的“内容”区域中作为LiteralControl输入。我试图添加按钮，但我可以接受其他建议。我只需要点击能力，所以我可以适当地填充我的GridView。在此先感谢您的帮助，以下是我的一些思考代码...

示例运行显示其中一个面板

这两个文件名需要是可点击的。有什么想法吗？

Answer 1

尝试添加面板而不是文字，以便您可以在其中添加按钮。

Panel pnl = new Panel();
LinkButton lnkbtnFile = new LinkButton();
lnkbtnFile.Text = "A Week Ago";
pnl.Controls.Add(lnkbtnFile);
AccordionPane lastWeek = new AccordionPane();
                lastWeek.HeaderContainer.Controls
                    .Add(pnl);
