CarouselView 2.3.0-pre2

ToddHardin

re:CarouselView-pre2
What is the recommended way to get a feeling for roughly when a stable release might be available?

I suppose this question is not isolated to the CarouselView, rather it is something I've been seeking to understand about all Xamarin releases.

I've searched for a release schedule, or potential release scheduled, etc. and have failed to find anything - my apologies if I've overlooked some information.

I'm wondering how to respond to questions from management at my company about our project release schedule risks if our dev team decides that something in a pre-release version is highly desirable to address one of our feature needs.

A CarouselView-pre2 package was just released to Nuget: https://www.nuget.org/packages/Xamarin.Forms.CarouselVIew

Other news: CarouselView is scheduled to be open sourced on Tuesday, August 2, 2016.

@HotTotem - big thanks for sharing your solution for page indicators - exactly what I needed to sort out

HotTotem

@ToddHardin glad you like it! Unfortunately using the material design on android removes the borders on the buttons and makes the dots invisible, ill add a solution to this in the post tonight

Pre 2 looks good. One thing I would say is make sure you clean and rebuild after upgrading otherwise you may get this error:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: The type initializer for 'Xamarin.Forms.CarouselView' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly or one of its dependencies.

iOS renderer is not jumping to the correct position on first load - its always at position 0.

I have updated the PageIndicator Project here : GitHub and the tutorial : hot-totem.com/blog/post/carouselview-pageindicators-xamarinforms to make it compatible with material design

anyone tried to use the itemselected event handler, it seems to have some really strange behaviours

HotTotem

@YongZhong yes i think it is acting weird... Go with the page selected event its more reliable

@BryanHunterXam Still on schedule to open source?

Like others I am also keen to have the ability to skip directly to a particular position without animation!

cheers.

That was yesterday and I can't find the source on Github...

Carousel work with Windows Phone ?

BryanHunterXam

The CarouselView is now open source:

@Naografix

From what I see in the source it support WinRT and UWP.

https://github.com/xamarin/Xamarin.Forms.CarouselView/blob/master/txt/src/carouselView/dev/Shared.Windows/CarouselViewRenderer.cs

Luccul

@NMackay So WinRT can work with Windows Phone Silverlight no ?

NMackay

@Naografix

No, I don't think so, someone correct me if I'm wrong. We're supporting UWP but nothing before it.

Is there any way to achieve a card-like view, as shown in the blog's image?

AndyBarajas

Anybody else having the background color of their listview turn grey when tapping outside of the list view in a carousel view? iOS only

AndyBarajas

Example of this bug in action is attached. Just click on the red or blue box view and see that the list view background turns gray.

Hi

I'm trying to make the carouselview (pre-2) clickable (through a tapgesturerecognizer) but in Android it's not working whereas in iOS it works perfectly.
Is it really working or am i doing something wrong?

Thanks

We had this problem. The only solution we could find that worked, was this one. Using a color transparent boxview over the element inside. It's kind of hackish, but it worked.

<cv:CarouselView.ItemTemplate>
    <DataTemplate>
        <Grid>
            <local:SomeView />
            <BoxView Color="Transparent">
                <BoxView.GestureRecognizers>
                    <TapGestureRecognizer />
                </BoxView.GestureRecognizers>
            </BoxView>
        </Grid>
    </DataTemplate>

AbelGarciaSaiz

Thanks @OddbjornBakke
Although it is working with that hack, it's not a solution for me because it is delegating the tap gesture on carousel items and not in the carousel itself whose binding would be in the page's viewmodel.

I would try to find another workaround

Thanks

We do something like (including that boxview hack):

<cv:CarouselView x:Name="carouselName" ... />

and then:

<cv:CarouselView.ItemTemplate>
    <DataTemplate>
        ...
        <TapGestureRecognizer Command="{Binding Path=BindingContext.SomeCommandToExecute, Source={x:Reference carouselName}}" CommandParameter="{Binding .}" />

Then the bindingcontext is the pages viewmodel, width a generic command, taking the carousel item viewmodel as a parameter.

There might be a lot better ways of doing this, but since this is a preview, I have not used that much time finding alternative solutions. So please tell if you find a better way

Hello everyone,

I have a Xamarin.Forms application where i use the new CarouselView. My main page is a TabbedPage where i have a navigation page for each tab with a content page. In one of my tab i have a CarouselView. It works perfectly on iOS but on Android, since the TabbedPage allows user to swipe to change tab, the CarouselView swipe is not working.

Is there a way to make it work ? Maybe by disabling the swipe on TabbedPage on Android ?

Thank you !

When I display a carousel of content pages, appearing and disappearing events don't seem to be called when position is changed.

Here's how I handled it

AdrianKnight

@ChaseFlorell So then the child items should be defined as views (in your case CarouselContentView : ContentView)? I suppose it doesnt make sense to use pages.

Hello,

I'm using CarouselView pre2.

Everything works fine on Android.

However, in iOS 8.1, it works fine until i try to navigate to another page (setting Detail to another page in MasterDetailPage) : i'm facing a crash...

iOS 9 is OK.

Has anyone got same issue ?

Thank you, have a nice day,

Antony

Guys, I'm having issue with System.TypeLoadException: Could not load type 'Xamarin.Forms.Platform.CarouselViewRenderer' from assembly 'Xamarin.Forms.CarouselView, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
I've tried rebuild project doesn't help.
Any ideas?

RyanWatson

Everything was working fine and Carousel View was working. All of a sudden this morning I keep getting this error. Any clue what would cause that to happen?

@Ron.Klintskey @RyanWatson Many renderers seem broken now. See Daniel's response here.

Thanks, I downgraded and that fixed my issue.

Jan-DavidStrk

Short question: Is the CarouselView (pre2) reliable for you? Because I nested it inside a TabbedPage and it randomly switches to the right / left tab instead of switching to the previous / next carouselview-item. Any ideas on how to fix that?

BadStorm

There is any way to use the CarouselView in vertical?

AdrianKnight

I just worked on enabling iOS TabbedPage to have sliding behavior like Android. I know CarouselView is intended for another purpose, but if you're interested, you could take a look here: https://github.com/xamarin/Xamarin.Forms/pull/434

Have following problem with WP platform, when try debug on Windows 10 mobile, catch unhandled exception, but it's successfully working in emulator 8.1

Attempt by method 'Xamarin.Forms.ItemsView+ItemsSourceProxy.get_SyncContext()' to access method 'Xamarin.Forms.BindingBase.TryGetSynchronizedCollection(System.Collections.IEnumerable, Xamarin.Forms.CollectionSynchronizationContext ByRef)' failed.

Does someone have the same problem, could you help me?

Anyone else having a problem where the order of their pages are changing? I have 7-8 pages and when I scroll to the last page and then back to the first page, the first page is different than what it was the first time.

Might have something to do with carouselview reusing cells. Some code will do this. Same goes for ListView etc.

Tried looking at this on Github, but couldnt even set the project up with spaces in the file path. Filed here: https://github.com/xamarin/Xamarin.Forms.CarouselView/issues/6

The complexity of setting this project up i.e. doing the steps here https://github.com/xamarin/Xamarin.Forms.CarouselView#opening-solution to even open the project is a real barrier for anyone looking to contribute to this project.

Any reason its so complicated to open / build?
