GridView事件不能正常工作

Question

我一直在寻找一个非常令人沮丧的问题。起初，RowDataBound事件在重写整个gridview之后并没有触发它的排序事件。这次它抱怨没有注册该事件的处理程序。这是个谎言！！！！！！！！ 我已经尝试了很多东西，而且我在这一点上绝望，我真的不知道发生了什么。任何帮助将不胜感激。

Working Event Not Working

为了避免进一步的重视第三方控制我改回GridView的到正规的ASP之一。 这就是现在的结构。 ...... 注意：没有足够的信誉来添加链接:(

解决它!!!!! 所以事实证明，这是一个单线，它崩溃了整个事情。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。不支付att因为我不知道它做了什么。我之前在其他网页上看到过我正在进行的项目，并没有造成任何麻烦。无论如何删除这条线使一切工作与常规gridview和我自己的组件。

SortableGridView你在页面中使用的是第三方控件，它不属于asp控件set.It是不一样的asp gridview控件。可能或可能没有onrowdatabound事件的机会，它将取决于控件创建者。您可以通过右键单击“SortableGridView”类并单击“定义”来查看SortableGridView类中使用的类和方法列表。
