Event Type


When you add a DesktopWindowXamlSource to your desktop application, by default the DesktopWindowXamlSource does not automatically handle focus navigation via keyboard events such as the Tab or arrow keys. Call the NavigateFocus method to programmatically give focus when the user navigates to the DesktopWindowXamlSource.

Handle GotFocus event to be notified when user enters the DesktopWindowXamlSource via some non-keyboard event, such as a mouse click, and you want to keep the state of the UI in the host desktop application up to date.
