Hello

I have a problem I have my note-taking app filtering by user's notebooks, using the user id. When I create a note, I use the notebook ID as an id for the note.

I tried to filter the notes, that each notebook has but I get strange behavior, sometimes notes appear, sometimes they do not, sometimes all the notebooks can see the same notes, sometimes when there are no notes, the app paint a note

merry Christmas

Hi, EduardoGomez-1870. When click one item of the 'notebooks', the selected event need to obtain the corresponding notebook ID. But in the 'MainPageViewModel.SeletedItemActionAsync' method which is called when selecting an item, the id is not passed. For the page xaml, it seems you're using a SfListView, the select event will be different with Xamarin.Forms.ListView. For the problem about third party, it's suggested to report the issue on its portal at: https://www.syncfusion.com/forums/xamarin.forms. You could search with the keyword as SfListView EventToCommandBehavior to check the related documentation for this function.

Try to pass the collectionView as the parameter to the 'SeletedItemCommand'.
