QUESTION
I've declared a FlipView control in XAML, and I want to bind it to a collection source defined and populated in code behind (.cs file). Furthermore, the texblock is to display a specific property of an item in the collection.
XAML declaration of FlipView:

Answered 2020-Sep-15 at 08:33As you mentioned you also see the same problem when using a ListView
instead of a flipview when either using a List
or ObservableCollection
I did some tests and it turns out that initializing the collection in the Page_Loaded
event messes up your databinding. Therefore you should define:

I have json which am supposed to decode and display in a flipview format or sliding format. In my json, there is information under the same section (having the same question_id) which has to be displayed on one page in a flipview.
The issue is that they are displayed differently or independently on different pages yet i want those with the same id to be displayed together on the same page

For your requirement, you could use current json structure directly. and pass sections field to ItemsControl
where in the FilpView
control DataTemplate
. Please check the following Xaml code. And we use Microsoft.Toolkit
(Expander
) to optimize the layout. And use CollectionVisibilityConverter
to control Expander display or not base on the sections count.
QUESTION
I have two screens, 1) Video calling screen 2) Chat screen.
I have implemented flip view using the library https://github.com/kevinstumpf/react-native-flip-view to show video calling screen as front screen, and when someone clicks on chat, flip the view and show chat as back screen.
I want to show a thumbnail camera view in chat and video calling screen with draggable view, it works on first load, however when I flip the screen, the PanGestureHandler stops working, although I can see the camera thumbnail view is still visible in the screen after the flip, however its position gets reset to top left corner (initial position) and drag is no more working.
Below is the code I am using.

QUESTION
I want to detect touch in the screen, and then trigger some actions. But I need to exclude some area, e,g. a flipview window. That means inside of the flipview window, no touch detect, only flip action works.
With below code, it will detect the touch action in the whole screen. But this is not what I want.
...ANSWER

The PointerPressed
event will bubble down through the FlipView
to Page. If you don't handle this event in FlipView
, and the page will catch PointerPressed
finally. For your requirement, you need to handle FlipView
PointerPressed
before bubbling.

I want to dynamically add new flip view item in UWP. So that I can add infinite items to my flip view. For example, to fetch hot news and show them one by one in flip view.

Answered 2019-Jun-10 at 08:44There are two things in play here. First, you don't need to assign a new instance of the whole view model to make a change - instead, you can just retrieve the existing view model and add the new item:
QUESTION
I wanted to finally update my MahApps.Metro with the NuGet Manager for my Project. In one WPF Window I use the FlipView Control and when I update Metro I always end up with an NullPointer Exception in the FlipView class.
It does not matter if I update to version 0.14 or 1.0.0 or 1.5.0 - it always crashes.
When I exclude the FlipView it starts but every window I call with .ShowDialog() does not show up.
Did anyone experienced the same?

Summary: I used a custom Style Template which caused the trouble. Removing it solved the problem.
