I have a ListView with Title and Url.

I want when users click on the url to open the current url with browser.

My ListView:

  <StackLayout>
        <ListView x:Name="lstNews" HasUnevenRows="True" ItemTapped="LoadNews">
            <ListView.ItemTemplate>
                <DataTemplate>
                    <ViewCell>
                        <ViewCell.View>
                            <Grid BackgroundColor="#454545">
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="auto"></RowDefinition>
                                    <RowDefinition Height="auto"></RowDefinition>
                                    <RowDefinition Height="2"></RowDefinition>

                                </Grid.RowDefinitions>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="auto"></ColumnDefinition>
                                </Grid.ColumnDefinitions>
                                <Label Grid.Row="0" Grid.Column="0" Text="{Binding TitleNews}" XAlign="Center" YAlign="Center" TextColor="#2bff00" FontAttributes="Bold" FontSize="Large" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand" VerticalTextAlignment="Center" HorizontalTextAlignment="Center"/>
                                <Label Grid.Row="1" Grid.Column="0" Text="{Binding UrlNews}" XAlign="Center" YAlign="Center" TextColor="White" FontAttributes="Bold" FontSize="Small" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand" VerticalTextAlignment="Center" HorizontalTextAlignment="Center"/>
                                <BoxView Color="#2bff00" HeightRequest="1" Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2"/>
                            </Grid>
                        </ViewCell.View>
                    </ViewCell>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>
    </StackLayout>

            foreach (var item in NewsList)

            }        
        }
    }
}

I want to tap on the Label on grid.row 1 "UrlNews" to be tapped and open the current url.

CodePudding user response：

use ItemTapped

<ListView ItemTapped="LoadNews" ... />

in your code behind

protected void LoadNews(object sender, ItemTappedEventArgs args)
{
  var item = (MyItemClass)args.Item;
  Launcher.OpenAsync(item.UrlNews);
}
