How to show a pop-up message when clicking the image in the .NET MAUI Rotator?

This section explains how to display a pop-up message when an image is clicked in the .NET MAUI Rotator. You can achieve it by following these steps:

Step 1: Initialize the Rotator control on the XAML page with the required assemblies.

XAML:

 <syncfusion:SfRotator x:Name="rotator" />

Step 2: Create a Model and ViewModel classes.

Step 3: Define a collection of images in the ViewModel class.

C#:

public class RotatorModel
{
    public RotatorModel(string image)
    {
        Image = image;
    }
    private string _image;
    public string Image
    {
        get { return _image; }
        set { _image = value; }
    }
}

public class RotatorViewModel
{
    public RotatorViewModel()
    {
        ImageCollection.Add(new RotatorModel("image1.png"));
        ImageCollection.Add(new RotatorModel("image2.png"));
        ImageCollection.Add(new RotatorModel("image3.png"));
        ImageCollection.Add(new RotatorModel("image4.png"));
        ImageCollection.Add(new RotatorModel("image5.png"));
    }
    private List<RotatorModel> imageCollection = new List<RotatorModel>();
    public List<RotatorModel> ImageCollection
    {
        get { return imageCollection; }
        set { imageCollection = value; }
    }
}

Step 4: Bind the collection to the Image property in the ItemTemplate. Use TapGestureRecognizer for event handling.

XAML:

<syncfusion:SfRotator
    VerticalOptions="Center"
    x:Name="rotator"  
    ItemsSource="{Binding ImageCollection}">
    <syncfusion:SfRotator.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Image Source="{Binding Image}"/>
                <Grid.GestureRecognizers>
                    <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped" />
                </Grid.GestureRecognizers>
            </Grid>
        </DataTemplate>
    </syncfusion:SfRotator.ItemTemplate>
</syncfusion:SfRotator>

Step 5: Implement the event method to show a pop-up message.

C#:

private void TapGestureRecognizer_Tapped(object sender, TappedEventArgs e)
{
    DisplayAlert("Image", "Rotator Item has been tapped", "Ok");
}
