QUESTION
I have searched around and I dont think I am finding the answer to my question. I am new to xamarin so i hope I am using the correct terminology. I am experimenting with custom cells in listviews. My aim is to reuse the custom cell throughout multiple parts of my application but when I use the event "ItemSelected" it comes back with the bindings to the custom cell and not my original listview itemsource bindings. I understand why I think but I am unsure how to bind the ItemSelected to the original source. Am I using the right method here? I am completely lost if I am honest.
This is my custom cell code:
...ANSWER
Answered 2021-Jun-03 at 06:11According to your code, when binding to a custom cell type's BindableProperty
instances, the UI controls displaying the BindableProperty
values should use the OnBindingContextChanged
override to set the data to be displayed in each cell.
QUESTION
This's my first question here, so hi everybody. I'm working on the mobile app in Xamarin.Forms with Prism. I've created ListView where shown data from the database.
When the user clicks in the selected row app should navigate to a new view and pass the selected item from ListView.
...ANSWER
Answered 2021-May-02 at 12:40As I can see you are already using Prism
and you have a List page with Items and you want to navigate to some details page based on the selected/taped/chosen item which the user taps in the ListView.
The idea is to move as much code and logic as we can to the view model and keep our code-behind. This is pretty easy to solve using Prism
and EventToCommand
behaviour.
In the example and answer below, I will show you how to solve this with few lines of code, with a nice code approach.
First of all, I recommend you use EventToCommand
behaviour, you can include it with prism xmlns, like this: xmlns:prism="http://prismlibrary.com"
, later on, you can use it with ListView.
Remove ItemSelected event from your ListView and move the markup about it to the part. Here is my code sample for the
ListView
which binds to some ObserverableCollection
of the Car models:
QUESTION
I know that the main problem comes from recursively calling FindFile()
. With recursively calling this function, my i
becomes 0. But I don't understand how I can fix this problem.
If possible, give advice on how to fix this bug without completely reworking all the functions below. Or provide a link where you can read about the correct initialization of icons in CListViewCtrl
.
ANSWER
Answered 2021-Apr-06 at 23:39You need to pass the value of i
as a reference to FindFile
so that when you call it recursively the value continues to increment.

QUESTION
I am trying to replace the action bar in a Xamarin android project with a custom toolbar. I want my toolbar to display a logo on the left, and then my menu icons on the right.
I followed this tutorial from Microsoft closely Replacing the Action Bar
But my menu icons no longer display (when I was using ActionBar, my menu icons displayed just fine). There is however a 3 dot overflow icon, but when clicking it nothing happens. Here is a screenshot of the built app with my custom toolbar:
I have tried:
- I thought my image view was blocking the menu icons, so I removed it but my menu icons do not show.
- Changing what MainActivty extends, I have tried Activity, and AppCompactActivity
- I thought my OnCreateOptionsMenu may not be getting called, So I tried:
toolbar.InflateMenu(Resource.Menu.actionbar);
I am stuck and not sure what is wrong here, I would appreciate any help!
Here is my Code:
Toolbar.xml

QUESTION
I want to customize a ListView
's ScrollViewer.HorizontalScrollMode
from codebehind. How can I do this?
It is easy in XAML:
...ANSWER
Answered 2021-Mar-09 at 21:27The ScrollViewer
properties (like VerticalScrollMode
, VerticalScrollBarVisibility
, etc) are attached properties (just like AutomationProperties are).
XAML actually provides two methods of setting these properties:
- The property system (
SetValue
andGetValue
) - The XAML accessor pattern
I find the SetValue
pattern super straightforward:
