Question

我有下面的代码，它添加标签和网页浏览很好。但是在2个标签后它将不再添加并继续抱怨radeditor2已经存在。我知道我没有添加相同的ID。而且不知道为什么它一直试图添加以前的标签而不是新标签。所以说我用radedtor1添加tab1。然后tab2与radeditor2。一切正常当我尝试使用radeditor3添加tab3时，它不会让我抱怨radeditor2已经存在。我注意到的一件事是，每次创建选项卡时都会触发RadMultiPage1_PageViewCreated。如果你创建了1，那么它将会触及该方法1次，2将会触及2次，依此类推。

所以请帮我解决这个问题。非常感谢你的时间

一个小小的错误可能会让你付出沉重的代价。我想出了我的问题，我将在这里发布，以防有人犯了与我一样的愚蠢错误。谢谢大家的时间

而不是rad_Editor.ID = "radEditor_" & Trim(txt_TabTitle.Text) 使用rad_Editor.ID = "radEditor_" & e.PageView.ID

动态添加tabstrip和multipageview
