Examples

The following example demonstrates how to use BrowserInteropHelper.IsBrowserHosted to determine if a Page is hosted in a browser.

// Detect if browser hosted
if (BrowserInteropHelper.IsBrowserHosted) 
{
    // Note: can only inspect BrowserInteropHelper.Source property if page is browser-hosted.
    this.dataTextBlock.Text = "Is Browser Hosted: " + BrowserInteropHelper.Source.ToString();
}
else 
{
    this.dataTextBlock.Text = "Is not browser hosted";
}

' Detect if browser hosted
If BrowserInteropHelper.IsBrowserHosted Then
    ' Note: can only inspect BrowserInteropHelper.Source property if page is browser-hosted.
    Me.dataTextBlock.Text = "Is Browser Hosted: " & BrowserInteropHelper.Source.ToString()
Else
    Me.dataTextBlock.Text = "Is not browser hosted"
End If

Remarks

A Page can be host agnostic and, consequently, can be loaded into several different types of hosts, including a Frame, a NavigationWindow, or a browser. This can happen when you have a library assembly that contains one or more pages, and which is referenced by multiple standalone and browsable (XAML browser application (XBAP)) host applications.
