Thanks for the links to the demos. Unfortunately, I'm unable to get the context menu to show when the user right-clicks on the column header. (We require a context menu for the actions users can take on each item, so using the item context menu to show/hide columns in not a viable solution.)
In our radgrid implementation, we simply use the built in context menu functionality. Can you provide a sample of how to implement this in a treelist?
Also, based on what I saw here
, it doesn't appear the persistence control will work as it doesn't store column settings (e.g., visibility, size, etc.). Is my interpretation of this incorrect or can these values indeed be stored between sessions?
