• Add IsBusy Property as shown in below 👇🏻 image.

private bool _isBusy;
public bool IsBusy
{
    get { return _isBusy; }
    set { SetProperty(ref _isBusy, value); }
}

• Add ButtonContent Property as shown in below 👇🏻 image.

public string ButtonContent
{
    get { return _buttonContent; }
    set { SetProperty(ref _buttonContent, value); }
}

private DelegateCommand _clickCommand;
public DelegateCommand ClickCommand =>

void ExecuteClickCommand()
{

}

Click Command Statements

Now we add following statements to click command.

• First we set the value of IsBusy property to true.

• This means we want to show Busy Indicator.

• Please add below code as shown below 👇🏻.

void ExecuteClickCommand()
{
    // Show busy indicator
    IsBusy = true;
}

• Next we run a new Thread.

• This Thread, imitate a long task.

• Add new Thread as shown in below 👇🏻 image.

• Please add below code as shown below 👇🏻.

async void ExecuteClickCommand()
{
    // Show busy indicator
    IsBusy = true;

    await Task.Run(() =>
    {

    });
}

• In above code, we use async and await keywords.

• These keywords, help us to do asynchronous programming.

• This Task.Run() method, run a new Thread and free UI thread.

• This await keyword, watch if this Task is completed or not.

• Now we add statement to make new Thread sleep for 5 sec.

• To sleep new Thread, add code as shown in below 👇🏻 image.

async void ExecuteClickCommand()
{
    // Show busy indicator
    IsBusy = true;

    await Task.Run(() =>
    {
        // Sleeping with 5 sec
        Thread.Sleep(5000);
    });
}

• Lastly, we set the value of IsBusy property to false as shown in below 👇🏻 image.

• This means we want to hide Busy Indicator.

• Please add below code as shown below 👇🏻.

async void ExecuteClickCommand()
{
    // Show busy indicator
    IsBusy = true;

    await Task.Run(() =>
    {
        // Sleeping with 5 sec
        Thread.Sleep(5000);
    });

    // Hide busy indicator
    IsBusy = false;
}

Final Result

Now we run the application as shown in below 👇🏻 image.

Until the Thread is sleeping we able to see Busy indicator to show user that some operation is running.

Until the operation complete, we see this Busy indicator.
