WPF Busy Overlay Or Busy Indicator Example In C#
Greetings all! I've been doing some research on how to add an overlay feature similar to an Ajax busy modal to one of my WPF projects. A simple approach led me to this topic WPF: Simple "Busy" Overlay . Since I'm using the traditional MVVM and not Simon Cropp’s Notify Property Weaver, I made this work by creating a WPF project using Visual Studio 2017 (installed in my workstation) and then copied the codes specifically BoolToVisibilityConverter.cs , BusyViewModel.cs , DelegateCommand.cs and MainWindow.xaml from his example at BitBucket . I also changed the IsBusy property to implement the OnPropertyChanged event private bool _IsBusy; public bool IsBusy { get { return _IsBusy; } set { _IsBusy = value ; OnPropertyChanged( "IsBusy" ); } } and added the implementation of that event. protected void OnPropertyChanged ( string propertyName) { if (PropertyChanged != null ) PropertyChanged( this , new PropertyChangedEventArgs(propertyName)
