Intro

In Windows Phone 8.1, anyone can take a screenshot by pressing the power button and the volume-up key at the same time. A customer was concerned about privacy in their enterprise app and asked me if they could disable this functionality for Windows Phone 8.1 (both WinRT and Silverlight apps). I researched this and found that this could be accomplished with the following code listed below:

For Windows Phone 8.1 Silverlight Apps

public MainPage()
{
    this.InitializeComponent();

    if (this.CanSetScreenCaptureEnabled())
    {
       this.SetScreenCaptureEnabled(false);
    }

}

For Windows Phone 8.1 Runtime Apps

public MainPage()
{
    this.InitializeComponent();
    ApplicationView.GetForCurrentView().IsScreenCaptureEnabled = false; 
}

Wrap-Up

I hope this helps someone else out there that runs into the same problem!
