Thanks for your feedback. I do have the resource files and have even desperately stuck copies of darn near every resource file and folder in my module's folder, the ~/admin/users/App_LocalResources and ~/App_GlobalResources folder but no success.
I do get localized values when (not using AJAX) hard coding the control onto the module or by adding through code (like controls.add), but when the control is served through a call back method (using AJAX), I do not get the localized labels.
I could go around this by creating my own User control without localization, but I want to minimize future problems if the user objects change in the future as they had recently and force the upgrade of so many controls. I'm trying the best I can to stick to the core controls.
Here are some more details of my current project...
We are using ComponentArt controls for some areas, which includes their treeview and callback controls.
Visual Studio 2005 is being used for development on Windows XP Professional, and development server is Windows 2003.
The treeview on the left side of the screen displays categories of affiliations based on the logged in user's affiliations and rights (custom database solution). i.e.: Referring Group, Referring Office, Referring Office Dept., Referring Physician, etc...
Upon expanding a node, entities affiliated to the user from that type will display. i.e.: Expanding Referring Physician will display Referring Physicians that the user is linked to.
If the user selects one of the items in the treeview, an AJAX call is made and a list of users linked to that item is returned through a callback.
If the user chooses to edit a user, another AJAX call is made which then performs a callback returning the control to edit the user.
I do not believe the Component Art controls are the root of the problem, but I could be wrong. I can try to use the Core functionality for AJAX, but could spend a lot of time to get the same results. We are using the Component Art controls because of the familiarity, ease of use and the "Loading..." display when waiting for the callback to return.
