推荐答案

事件需要在后面的代码中创建，以便事件触发，因为否则在恢复viewstate时它们将不存在.因此，即使您复制了通常事件中存在的javascript，也不会触发.对于我来说，这些事件似乎都没有客户端版本，RenderPreText和RenderPostText方法似乎是向客户端添加客户端事件的最可能方法.

The events need to be created in the code behind, in order for them to fire, because otherwise they will not exist when viewstate is restored. Therefore, even if you copied the javascript that exists for a usual event, it would not fire. None of the events seem to have a client side version, the RenderPreText and RenderPostText methods seem like the most likely way to add a client side event to a node, to me.

TreeNode类具有工具提示属性.如果不合适，您首先需要做我说的话，尝试找到一种将HTML/Javascipt注入TreeNode对象的方法.

The TreeNode class has a tooltip property. If that does not suit, you need to do what I said in the first place, try to find a way to inject your HTML/Javascipt into the TreeNode objects.
