c# - 如何在更新面板中打开模态弹出窗口？

Question

我有下一个要求:显示多个选项的 DropDownList选择不同的客户，一旦我选择不同的客户并单击下拉列表下方网格中的按钮 应该显示我选择的那些客户的报价，并且如果我点击一个特定的列，应该打开一个弹出窗口显示详细信息该报价。

有不同的场景:

1.- 如果我使用更新面板并在其中放置下拉列表和网格，当我在该特定列中单击时弹出不起作用。

2.- 如果我不使用更新面板，一切都很好，除了刷新网页。

3.- 如果我在选择下拉列表中的某些内容之前用数据加载网格，弹出窗口会一直工作，直到我在下拉列表中选择某些内容，这就是如果下拉列表触发的事件以某种方式影响网格或弹出窗口，并且这里的一切都在更新面板内。

¿你对我有什么建议？

我有网页的下一个代码:

Answer 1

看起来您实际上是将“打开模态对话框”代码挂接到 tplIndividualQuotations 中的链接上通过基于 class="modal" 的 JavaScript ？

我相信您执行此操作的代码只会在页面加载时触发一次(使用类似 jQuery $() 方法或类似方法)。

问题是当 UpdatePanel 被重新加载时，这段代码不会再次运行并 Hook 新的 <a> 上的代码。已添加到页面的元素。

当您使用 UpdatePanels 时，您将需要连接到 ASP.NET AJAX PageRequestManager

您需要向 endRequest 添加一个方法事件 Hook 是:

Raised after an asynchronous postback is finished and control has been returned to the browser.

所以你会有这样的东西:

<script type="text/javascript">
  Sys.WebForms.PageRequestManager.getInstance().add_endRequest(pageLoaded);

  function pageLoaded(sender, args) {
     //Code to hook up modal load here...
  }
</script>
