My page within a frame takes to time to load meaning the controls take some time to appear on the page for the first time. Where in my main window.cs file should I set the IsBusy = true.I have no idea how to use busy indicator.When should I switch it to true or false. please guide me how should I use it ? Thanks in advance.
Generally you would set the busy indicator before you start doing a load of heavy processing so that is dependant on your code.
It would normally before just before you spawn a background thread to do a load of work leaving the UI to say it's busy at the moment and when the thread is completing then "unbusy" the UI.
