Unable to delete Item swipe view

Question

Hello everyone

For some reason, my SQLite cannot populate a CollectionView from a viewModel (I load the data in the onApeared, and try to load the data to a collectionView in the viewModel) None of these worked so I opted for code-behind.

I declared a swipe view, to delete the item, the problem comes, when I want to delete the item, if I try to use MVVM I can't because my data is not in the view model.

I tried to access my ObservebableCollection in the code behind, from the view model, and remove it, but for some reason my Observable collectino is null,

I also tried to notify the code behind by using the messaging center and nothing

The biggest problem is that from the code behind, I cannot get the item that is currently swiping

At least with MVVM I can do something like {x:bindindg} and send the entire object to the view model

Is someone wants to poke around with it and help me, here is the link

Hello,

Welcome to Microsoft Q&A!

AddressTablePage does not receive the message because you set different formatting on sending/subscribing, you should set the generic type when sending message .

In AddressTableVM ,modify the code as below

MessagingCenter.Send<Address>(item as Address, "deleted");

Then the message would be received as expected.

Thank you.
