How to navigate a page while tapping .NET MAUI ListView's item using MVVM?
The .NET MAUI ListView (SfListView) allows you to navigate to another page when an element in the ListViewItem is tapped. This can be achieved by adding a GestureRecognizer to that element in the ItemTemplate.
XAML
Add TapGestureRecognizer to the Image and bind the Command to navigate to a page when the image is tapped from the ViewModel.
<ContentPage.Content>
<Grid>
<listView:SfListView x:Name="list" ItemSize="70" ItemsSource="{Binding contactsinfo}" ItemSpacing="0,0,5,0" SelectionMode="Single">
<listView:SfListView.ItemTemplate>
<DataTemplate x:Name="ItemTemplate">
<ViewCell>
<ViewCell.View>
<Grid x:Name="grid" RowSpacing="1">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="1" />
</Grid.RowDefinitions>
<Grid RowSpacing="1" Padding="10,0,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="{Binding ContactImage}"
VerticalOptions="Center"
HorizontalOptions="Center"
HeightRequest="50"/>
<Grid Grid.Column="1"
RowSpacing="1"
Padding="10,0,0,0"
VerticalOptions="Center">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Label LineBreakMode="NoWrap"
TextColor="#474747"
Text="{Binding ContactName}"
FontSize="12">
</Label>
<Label Grid.Row="1"
Grid.Column="0"
TextColor="#474747"
LineBreakMode="NoWrap"
Text="{Binding ContactNumber}"
FontSize="12">
</Label>
</Grid>
<Grid Grid.Row="0"
x:Name="temp"
Grid.Column="2"
RowSpacing="0"
HorizontalOptions="End"
Padding="0,10,10,0">
<Image Source="navigate.png">
<Image.GestureRecognizers>
<TapGestureRecognizer
Command="{Binding Path=BindingContext.TapCommand, Source = {x:Reference list}}" CommandParameter="{Binding}" />
</Image.GestureRecognizers>
</Image>
</Grid>
</Grid>
<StackLayout Grid.Row="1" BackgroundColor="#E4E4E4" HeightRequest="1"/>
</Grid>
</ViewCell.View>
</ViewCell>
</DataTemplate>
</listView:SfListView.ItemTemplate>
</listView:SfListView>
</Grid>
</ContentPage.Content>
C#
In the ViewModel, navigate to another page using the INavigation interface when the tap command is invoked.
public class ContactsViewModel : INotifyPropertyChanged
{
#region Fields
private Command<object> tapCommand;
private INavigation navigation;
#endregion
#region Properties
public ObservableCollection<Contacts> contactsinfo { get; set; }
public Command<object> TapCommand
{
get { return tapCommand; }
set { tapCommand = value; }
}
public INavigation Navigation
{
get { return navigation; }
set { navigation = value; }
}
#endregion
#region Constructor
public ContactsViewModel(INavigation _navigation)
{
navigation = _navigation;
tapCommand = new Command<object>(OnTapped);
}
private async void OnTapped(object obj)
{
var newPage = new Page1();
newPage.BindingContext = obj;
await Navigation.PushAsync(newPage);
}
#endregion
public event PropertyChangedEventHandler PropertyChanged;
}Output
