我有招聘项目。在这个项目中，我有一个网格视图，其中包含所有空缺的详细信息。除此之外还有按钮。当用户点击此按钮时，该行下方的另一个网格中将显示该特定空缺的可用面试时间表。我做的是我在表格中放置了网格视图，表格最初是不可见的。当用户单击图像按钮时，我当时尝试从网格视图中查找表，但无法找到它。 这是我的.aspx页面的代码

请告诉我我的问题......
答案 0 :(得分：1)
您提供的代码太多，无法轻松阅读。您必须将其缩小到特定点。
让我试着帮助您解决具体问题。
如果设置控件visible=false，它将不会在客户端呈现，并且您无法在客户端稍后显示该控件。看看这个类似的线程，以了解如何继续：Want to make the visibility true from client side of the control which made invisible from server side
