Methods
| Improve this Doc View SourceOnFragmentNavigation(FragmentNavigationEventArgs)
This method is called when fragment navigation occurs on a page - either because a fragment was present in the original Uri that navigated to this page, or because a later fragment navigation occurs.
Declaration
protected virtual void OnFragmentNavigation(FragmentNavigationEventArgs e)Parameters
| Type | Name | Description |
|---|---|---|
| FragmentNavigationEventArgs | e | The event arguments, containing the fragment navigated to |
Remarks
This should be used rather than signing up for NavigationService.FragmentNavigation because that event may be difficult to sign up for in time to get the first fragment navigation.
OnNavigatedFrom(NavigationEventArgs)
This method is called when a Page has been navigated away from, and is no longer the active Page in a Frame. This is a good time to save dirty data or otherwise react to being inactive.
Declaration
protected virtual void OnNavigatedFrom(NavigationEventArgs e)Parameters
| Type | Name | Description |
|---|---|---|
| NavigationEventArgs | e | The event arguments |
Remarks
This is similar to signing up for NavigationService.Navigated, but this method is preferred as then you do not need to remove the event handler from NavigationService to avoid object lifetime issues.
OnNavigatedTo(NavigationEventArgs)
This method is called when a Page has been navigated to, and becomes the active Page in a Frame. This method is the preferred place to inspect NavigationContext, and react to load-time information and prepare the page for viewing.
Declaration
protected virtual void OnNavigatedTo(NavigationEventArgs e)Parameters
| Type | Name | Description |
|---|---|---|
| NavigationEventArgs | e | The event arguments |
Remarks
This should be used rather than Loaded because Loaded signifies you have been added to the visual tree, but that could potentially happen more than once during a logical navigation event, in some advanced scenarios. This method is guaranteed to be called only once when the Page becomes active.
OnNavigatingFrom(NavigatingCancelEventArgs)
This method is called when a Page is about to be navigated away from.
Declaration
protected virtual void OnNavigatingFrom(NavigatingCancelEventArgs e)Parameters
| Type | Name | Description |
|---|---|---|
| NavigatingCancelEventArgs | e | The event arguments. If Cancel is set to true, it will cancel the pending operation that triggered this method call. |
Remarks
This is similar to signing up for NavigationService.Navigating, but this method is preferred as then you do not need to remove the event handler from NavigationService to avoid object lifetime issues.
