列表框不会保留在Firefox中

Question

Firefox目前给我带来了一些问题，我无法理解它们。

我有两个列表框，一个在加载页面时填充，另一个在选择第一个项目时单击查看按钮。我遇到的问题是第二个列表框只填充一瞬间，然后删除所有内容。该功能适用​​于我测试的所有其他浏览器.. IE，Chrome和Safari ..

    }
    #endregion
  }
}

有了这个，还有一些以前没有描述的功能，并且这个Firefox在启动editBtn_Click时也不会保持数据/保持控件可见。

如果还有什么我可以清理的话，我会尽力改写或其他任何事情。

谢谢。

我不知道发生了什么，但它现在正在运作。我重建了.cs页面并重新编译了整个网站，一切正常。还清除了所有浏览器的缓存..
