WPF loading spinner

Question

The goal is to display the information that the application is working. So I\'m looking for an intelligent implementation sample of a loading spinner using WPF / MVVM.

Answer 1

use an enum type to indicate your ViewModel's State

public enum ViewModeType
{
    Default, 
    Busy
    //etc.
}

then in your ViewModels Base class use a property

public ViewModeType ViewMode
{
    get { return this.viewMode; }
    set
    {
        if (this.viewMode != value)
        {
            this.viewMode = value;
                            //You should notify property changed here
        }
    }
}

and in view trigger the ViewMode and if it is busy show busyindicator:
