                            </StackLayout>

                        </DataTemplate>

                    </rotator:SfRotator.ItemTemplate>

                </rotator:SfRotator>

i tried this 

    private void Rotator_ItemTapped(object sender, EventArgs e)

        {

            var itemselected  = e. as USER_PHOTOS_MODEL;

            if(itemselected!=null)

            {

                m_selected_image = itemselected; 

            }

        }

 e event args does not contain an item

Hi Vuyiswa,

Greetings from Syncfusion.

We have validated your query and we have prepared sample based on your requirement using ItemTapped event and get the SelectedItem using rotator tems collection and selected index. We have prepared a sample for your reference get the sample and code snippet from below.

Code Snippet: 

  

 XAML.cs:
private void rotator_ItemTapped(object sender, EventArgs e)

          var itemSelected = viewModel.ImageCollection[rotator.SelectedIndex] as RotatorModel;
          if (itemSelected != null)
          {
              m_selected_image = itemSelected.Image;
          }
}

Good Day Admin 

Your example solved my problem. In the future are you looking at adding a selected item property to the Rotator ? Because Selectedindex option requires one to save the binded items of the Rotator to a variable. 

Thanks my Issue is resolved
