Question

我有一个模态弹出窗口，从LinkButton内的GridView启动。在Modal Popup中有3 TextBox和3 GridView。用户从GridView行中选择项目，然后在文本框中填充这些项目。

当用户选择GridView行时，模式弹出窗口将关闭。如果再次打开模态弹出窗口，则会填充TextBox，但我需要模态弹出窗口保持打开状态。

任何人都可以阐明为什么会发生这种情况以及我可以做些什么来绕过它？如果您需要查看一些代码隐藏，请告诉我。

提前致谢！

有点晚了，但你可以打电话

modalPopupExpander.Show（）;

可能的方法是注册模态内容页面的事件。

选择gridview行/ ASP / AJAX / C＃时，模态弹出关闭
