New Post: Any news on support for the Phone Toolkit 7.1 - LongListSelector?

rickengle — Sat, 21 Jul 2012 14:54:48 GMT

I saw a post that support for the Phone Toolkit was coming. What's the status on that? Has anyone already written an extension for LongListSelector?

Thanks,

Rick

New Post: what does it store when calling SaveState?

mrlacey — Tue, 06 Mar 2012 20:36:17 GMT

If you switch to the main menu and then launch the app from there, you are not recovering from tombstoning, you are launching a new instance of the app. The standard behaviour for such an action is to not restore the state of the app.

To be clear you are not tombstoning if you launch a new instance of the app.

TombstoneHelper only supports tombstoning, not persisting information between instances of apps. If you want to persist information or state between app instances you'll need to do that yourself and put the information in IsolatedStorgeSettings or a file in IsolatedStorage.

For an example of what's saved, you can examine the State property of the page after calling SaveState().
Alternatively, you can see what and how state is saved for each type by looking at the Save() method in each of the XxxxxTombstoner files.

my app is very simple, it has a stack panel which, UserControls are added to when clicking on a button like so:-

void btnAddPlayer_Click(object sender, EventArgs e)
{
	PlayerControl sbItem = new PlayerControl();
	ctlPanel.Children.Add(sbItem);	
}

Playercontrol is a simple control inherited from UserControl, it has 2 textboxes on it...

when I switch between apps everything is ok, its only tombstoned if you switch to the main menu and then load the app from the menu (instead of just switching/multi-tasking back to it)

when it is tombstoned the controls are no longer in the stackpanel... Id like it to be able to reload all of the added PlayerControls (and whatever text is set... and if possible there are some variables that are set aswell when the textbox is changed) ... with as little code as possible :)

any ideas?

Thanks

New Post: Panorama

mrlacey — Fri, 13 Jan 2012 10:30:32 GMT

Changing the selected (default) item in the panorama (which is what would be saved and restored when tombstoning) has the effect of moving the background relative to the items. It you have an image for the panorama background than this can be a big change.

I've known lots of people see the consequence of this and then decide they didn't want it. As such I made this opt in so you don't get unexpected and often unwanted behaviour as standard.

As it's VERY rare to have more than one panorama in an app I felt this wasn't adding a lot of overhead if you did want it.

I hope that clears it up.

Maybe a stupid question, but why is the Panorama control not included by default?

Hello! Thanks for all the efforts done to make this library. I have some issues though.. and don't understand why. I've included your "two line code" method and am testing my app in the emulator.

I've activated the tombstoning option for debuging. all my controls have names; i then press the 'home' button and when i go back to my app i still see the "Resuming" loading message. I have in my App.xaml.cs a bool to see if my app was dormant or tombstoned :

WasTombstoned = !e.IsApplicationInstancePreserved;

and in my xaml view page i have :

protected override void OnNavigatedTo(NavigationEventArgs e)

{ if (App.WasTombstoned == true)

{ this.RestoreState(); }

}

protected override void OnNavigatingFrom(System.Windows.Navigation.NavigatingCancelEventArgs e)

{ this.SaveState(e); }

What am i doing wrong?

        }

I hope this is useful to you...

New Post: Problem with user controls

mrlacey — Mon, 14 Nov 2011 09:54:30 GMT

@pgmariotti can you share the XAML for the page?
What are you expecting to restore? Just the selected Pivot or anything else as well?
Are you specifying any type(s) when you call `SaveState`?

p.s. sorry for slow response. The notification of this only just got to me. :(

New Post: Problem with user controls

pgmariotti — Thu, 03 Nov 2011 13:52:13 GMT

I have a problem with a pivot page that includes several copies of a user control in its xaml (one on each element of the pivot). On return to the page TombstoneHelper terminates the App with an exception as follows: $exception {"Value does not fall within the expected range."} System.Exception {System.ArgumentException}.

If I remove the SaveState/RestoreStare from the page being navigated to, everything functuions properly.

Can you take a look please?

Great spot.

Yes, item 1 is a typo. I updated the sample when I added support for the NavigatING version but must have missed the base method.
Actually, it's not necessary to call the base methods at all as they don't actually do anything. (Must blog about this soon.)

When it comes to calling SaveState, passing the NavigatingCancelEventArgs is completely optional and only available in OnNavigatINGFrom, not OnNavigtEDFrom.
I'd recommend always passing it as it will improve performance when navigating is triggered by pressing the hardware back button.
It's optional to maintain backwards compatibility with the first version of this library which only supported OnNavigatEDFrom.

I'll update the sample code to always use best practice.

Matt.

New Post: Names of events involved (in sample code)

Hi, first of all, thanks for the library.

[edited item 1, because found the answer on the sample code]

The method on the base class is different than the one overriden:

    protected override void OnNavigatingFrom(System.Windows.Navigation.NavigatingCancelEventArgs e)
    {
        this.SaveState(e); 

        base.OnNavigatedFrom();
    }

Typo, right?

Second, on the sample below, the event e is not being passed in the generic version. I see it can be passed on the routine itself (the overload exists). Should we pass it or is it even ignored. If so, shouldn't be mandatory to ensure future compatibility? e is included in the basic sample after all...

 this.SaveState<ListBox, TextBox>();  <-- e is missing

Again, thanks.

@mailmugu How are you starting the app again after pressing the windows key? If you're not doing it via the back button then it shouldn't retain state.

codeplex doesn't have a file upload facility for discussion/issues but you could put the repro in SkyDrive or similar.

sorry for that ... my issue is I m not able to tombstone the application page... I type some text to text boxes like "Name,Tags, and description" . Then I press the windows button to go back to main menu. Now again launch my application now my upload page should appear with the entered text in text boxes .But I m getting only my MainPage.xaml. Dont know what is the real issue.

I dont know how to upload the entire working code . Please let me know how to upload so that u can see what my app is doing. I will also make the changes which you have mentioned ... thanks a lot

@mailmugu
You've posted the same block of code twice.
Even that isn't helpful in identifying what your issue is.
Please provide a complete working example which demonstrates your issue. Or ALL the elements to recreate it. (This shoudl include details of any dependencies or other classes/libraries you are using.)

You still haven't said what the actual issue you are experiencing is.

There are a few things I can conclude/suggest from the above code though:

I'd do away with using both PhotoChooser and CameraCapture tasks as PhotoChooser can be used to capture pictures from the camera also. (see http://msdn.microsoft.com/en-us/library/microsoft.phone.tasks.photochoosertask.showcamera(v=vs.92).aspx)
While you haven't identified where you're getting the ControlTiltEffect namespace from but I'd be amazed if you really need to repeatedly call "TiltEffect.SetIsTiltEnabled()"
You should set up your tasks and their callbacks in the page's constructor (not after the page has loaded) or they may not work correctly.
While you haven't shown what it does, having an "App.Quit()" method is probably a bad idea. You can't/shouldn't forcibly exit your app. It will fail marketplace certifiction if you do. Respect the back button and it's standard/default behaviour.
