Açıklamalar

Örneğin, burada gösterilen stili oluşturmak için geliştiriciler aşağıdaki XAML veya C# kullanabilir:

<ContentPage ...
             xmlns:controls="clr-namespace:Xaminals.Controls">    
<Shell.SearchHandler>
<controls:MonkeySearchHandler Placeholder="Enter search term"
                                      ShowsResults="true">
<controls:MonkeySearchHandler.ItemTemplate>
<DataTemplate>
<Grid Padding="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.15*" />
<ColumnDefinition Width="0.85*" />
</Grid.ColumnDefinitions>
<Image Source="{Binding ImageUrl}"
                               Aspect="AspectFill"
                               HeightRequest="40"
                               WidthRequest="40" />
<Label Grid.Column="1"
                               Text="{Binding Name}"
                               FontAttributes="Bold" />
</Grid>
</DataTemplate>
</controls:MonkeySearchHandler.ItemTemplate>
</controls:MonkeySearchHandler>
</Shell.SearchHandler>
    ...
</ContentPage>

Shell.SetSearchHandler(this, new MonkeySearchHandler
{
    Placeholder = "Enter search term",
    ShowsResults = true,
    DisplayMemberName = "Name",
    ItemTemplate = new DataTemplate(() =>
    {
        Grid grid = new Grid { Padding = 10 };
        grid.ColumnDefinitions.Add(new ColumnDefinition { Width = new GridLength(0.15, GridUnitType.Star) });
        grid.ColumnDefinitions.Add(new ColumnDefinition { Width = new GridLength(0.85, GridUnitType.Star) });

        Image image = new Image { Aspect = Aspect.AspectFill, HeightRequest = 40, WidthRequest = 40 };
        image.SetBinding(Image.SourceProperty, "ImageUrl");
        Label nameLabel = new Label { FontAttributes = FontAttributes.Bold };
        nameLabel.SetBinding(Label.TextProperty, "Name");

        grid.Children.Add(image);
        grid.Children.Add(nameLabel, 1, 0);
        return grid;
    })
});
