I have a listview, within the list view I have an entry box. I want to run some code after the entry box becomes unfocused which I have got working with the xct event to command behavior, but I would like the command to receive the object from the listview that the entry is inside.
(sudo xaml)
<ListView Name = ReportGrid>
<DataTemplate>
<ViewCell>
<StackLayout>
<Entry Text="0.00" VerticalOptions="Center" FontSize="16" BackgroundColor="White" Margin="10, 0, 0, 0">
<Entry.Behaviors
<behaviors:EventToCommandBehavior EventName="Unfocused" Command="{Binding Source={Reference CountLocationTabView}, Path=BindingContext.QtyEntryUnfocused}"
CommandParameter="{Binding Source={Reference ReportGrid}, Path=SelectedItem}" />
</Entry.Behaviors>
</Entry>
<StackLayout/>
<ViewCell/>
<DataTemplate/>
<ListView/>
I have seen examples of this where events from the listview are turned into commands but what about the elements within? thanks in advance.
Based on your code,I created a simple demo, and it works properly.
You can refer to the following code:
<ListView ItemsSource="{Binding items}" HasUnevenRows="True" HeightRequest="240" x:Name="Listview">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Frame Padding="0" >
<Grid Padding="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.5*"></ColumnDefinition>
<ColumnDefinition Width="3*"></ColumnDefinition>
<ColumnDefinition Width="3*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label x:Name="DistNumber" Text="{Binding DistNumber}" FontSize="18" Grid.Column="1" HorizontalTextAlignment="Start" VerticalOptions="Center"/>
<Entry x:Name="CountEntry" Placeholder="Choose Quantity"
Text="{Binding Count}"
Grid.Column="2" HorizontalTextAlignment="Center" >
<Entry.Behaviors>
<behaviors:EventToCommandBehavior
EventName="Unfocused"
Command="{Binding Path=BindingContext.EntryUnfocused, Source={x:Reference Listview}}" CommandParameter="{Binding .}" />
</Entry.Behaviors>
</Entry>
</Grid>
</Frame>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
The ViewModel is:
public class MyViewModel
{
public ObservableCollection<SomeItem> items { get; set; }
public ICommand EntryUnfocused { get; protected set; }
public MyViewModel() {
items = new ObservableCollection<SomeItem>();
items.Add(new SomeItem { Name = "item1", DistNumber = "1", Count = 1,Quantity = 1 });
items.Add(new SomeItem { Name = "item2", DistNumber = "2", Count = 2, Quantity = 2 });
items.Add(new SomeItem { Name = "item3", DistNumber = "3", Count = 3, Quantity = 3 });
items.Add(new SomeItem { Name = "item4", DistNumber = "4", Count = 4, Quantity = 4 });
items.Add(new SomeItem { Name = "item5", DistNumber = "5", Count = 5, Quantity = 5 });
items.Add(new SomeItem { Name = "item6", DistNumber = "6", Count = 6, Quantity = 6 });
EntryUnfocused = new Command(CompletedCommandExecutedAsync);
}
private void CompletedCommandExecutedAsync(Object obj)
{
SomeItem item = (SomeItem)obj;
System.Diagnostics.Debug.WriteLine("<----- item Name = " + item.Name + "<-----> item Count = " + item.Count);
}
}
