你走在正确的轨道上。使用Treelist肯定是要走的路。阅读一些关于如何将图像添加到树状列表等的文章。

您将不得不迭代通过树形图来更新状态。没有其他办法。或者将树状列表绑定到基础数据源并迭代它...例如行。除非您的聊天应用程序中有20.000个用户，否则它将足够快。

You were on the right track. Using Treelist is definately the way to go. Read some articles on how to add images to the treelist etc.

You will have to iterate through the treelist to update statusses though. There is no other way. Or bind the treelist to an underlying datasource and iterate through that .. e.g Rows. Unless you have like 20.000 users in your chat application it will be fast enough.
