How to Obtain the Selected Index in .NET MAUI Rotator (SfRotator)?

This document describes how to obtain the selected index in the .NET MAUI Rotator. We can achieve it by following the steps below,

Here, the SelectedIndex property is used to get the index of the selected item.

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

Step 2: Add items to the Rotator using SfRotatorItem.

Step 3: Implement the SelectedIndexChanged event in the Rotator control.

Step 4: Use the SelectedIndex property in the selection changed event to get the index of the selected item.

The following code demonstrates how to get the selectedindex in SfRotator.

XAML

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

C#

public partial class MainPage : ContentPage
{

    public MainPage()
    {
        InitializeComponent();
        
        List<SfRotatorItem> collectionOfItems = new List<SfRotatorItem>();
        collectionOfItems.Add(new SfRotatorItem() { Image = "image1.png" });
        collectionOfItems.Add(new SfRotatorItem() { Image = "image2.png" });
        collectionOfItems.Add(new SfRotatorItem() { Image = "image3.png" });
        collectionOfItems.Add(new SfRotatorItem() { Image = "image4.png" });
        collectionOfItems.Add(new SfRotatorItem() { Image = "image5.png" });
        
        rotator.ItemsSource = collectionOfItems;
    }
}

        private void rotator_SelectedIndexChanged(object sender, Syncfusion.Maui.Core.Rotator.SelectedIndexChangedEventArgs e)
        {
            DisplayAlert("Message", "Selected Index : " + rotator.SelectedIndex, "Ok");
        }
