Xamarin.Forms DLToolkit FlowListView How to get selected item?

Question

In my project I have to work with this plug-in: https://github.com/daniel-luberda/DLToolkit.Forms.Controls/tree/master/FlowListView/DLToolkit.Forms.Controls.FlowListView

Here is the part of my XAML:

    <flv:FlowListView 
        IsGroupingEnabled="true"
        FlowGroupDisplayBinding="{Binding Path=Letter}"
        FlowColumnCount="2" 
        FlowItemsSource="{Binding CitiesAlphabet}"
        FlowItemTappedCommand="{Binding TapCity, Mode=TwoWay}"
        x:Name="CityList"
    >

What is the "FlowItemTappedCommand"? Is it TapGestureRecognizer instead of ItemSelected? How should I implement this command, and how can I get now selected (tapped) item in ViewModel?

Is there any detailed manual with examples how to work with this plug-in?

Answer 1

FlowItemTappedCommand="{Binding CityTappedCommand}"

Implementation of the command:

public ICommand CityTappedCommand{ get; set; }

You can initialize it in the constructor of the viewmodel

CityTappedCommand = new Command(() => YourSub());

To get the selected item, you can add the following in your xaml:

FlowLastTappedItem = "{Binding SelectedCity}"

and then get SelectedCity in you viewmodel.
