scriptmanager

问题 I am having what I believe should be a fairly simple problem, but for the life of me I cannot see my problem. The problem is related to ScriptManager.RegisterStartupScript, something I have used many times before. The scenario I have is that I have a custom web control that has been inserted into a page.

问题 I've read through the net but haven't found a solution to the following problem. I have this example page (_ScriptManager.aspx) with a ScriptManager , an UpdatePanel , a MultiView with two Views and two LinkButtons two switch between the views.
