I have a Telerik Treeview on an aspx page housed inside of a Master Page. There is also an ascx user control on the page as well. Both controls are embedded in Ajax proxies for refresh. When the ascx is modified, it fires the TreeView Ajax proxy in order to refresh the TreeView. The web site works great for most users (including testers and developers). However, for a few select users, the TreeView doesn't refresh. The user must press the Browser Refresh button in order to have the TreeView refresh. I have had one of the suspect users log on to my machine and run the website. It still doesn't work for them, although it works for me. Does anyone have any idea as to why this might be happening?
More info: the suspect user logins have this refresh issue on every machine they try it on
