GridView 事件无法正常工作

Question

我一直在努力寻找一个非常令人沮丧的问题。起初是没有触发的 RowDataBound 事件，现在重写了整个 gridview 之后，它是排序事件。这次它抱怨没有为事件注册处理程序。这是个谎言！！！！！！！！ 我已经尝试了很多事情，在这一点上我很绝望，我真的不知道发生了什么。任何帮助将不胜感激。

为了避免进一步关注第三方控件，我将 gridview 改回了常规的 asp。 这就是现在的结构。 …… 注意：没有足够的声誉添加链接:(

您在页面中使用的SortableGridView是第三方控件，它不属于asp控件集。它与asp gridview控件不同。可能会或可能不会发生onrowdatabound事件。这取决于控件创建者.您可以通过右键单击“SortableGridView”类并单击“转到定义”来查看 SortableGridView 类中使用的类列表和方法。

Answer 2

解决了！！！！ 所以事实证明，这是一条让整个事情崩溃的单行代码。在数据绑定包装函数中有一个 ContactsSGV.Dispose() 调用，它有效地解除了处理程序的绑定。我以前没有注意它，因为我不知道它到底做了什么。我之前在我正在从事的项目的其他页面上看到过它，它没有造成任何麻烦。无论如何，删除这条线使一切都与常规的 gridview 和我自己的组件一起工作。
