Is there a simple way to persist the Quick Access Toolbar selections made by a user?
Currently there is no built in save/load functionality in the xamRibbon. You should submit a suggestion for adding this. In the interim you would need to save this manually. You could possibly iterate the Items collection of the QuickAccessToolbar and save out the TargetId of the QatPlaceholderTool instances in that collection and then use that to build new QatPlaceholderTool instances when the application is loaded.
Did you get this working saving QAT when user logged in next time.
Please reply me ASAP.
