  I'd use System.Linq and filter the list...

  var toggledUsers = listName.Where(w=>w.SwitchBool == true).ToList();

  You have to filter the ObservableCollection, not the listview

  You need to add using System.Linq as a reference at the top. Also it's not an extension for ListView, it's an extension on IEnumerable which is any list. You need to add the Where() statement on the end of your ListViews ItemSource list.

  Hi @seanyda and @AlessandroCaliaro Is it possible to get all selected users using Toggled="OnToggledEvent"

  There are many different approaches you can take. Using the OnToggledEvent would allow you to add/remove items to a list as it's toggled. But it really depends what approach you want to take. System.Linq like I described earlier would be the quickest way.. but it depends how you've wrote the code.

  @AlessandroCaliaro and @seanyda I started working with OnToggledEvent and trying to get the id of the toggled item.
  I try like below but getting an exception:

  public class MyToggledEventArgs : EventArgs
          {
              public UserProfileHBList MyItem { get; set; }
              public MyToggledEventArgs(UserProfileHBList item)
              {
                  this.MyItem = item;
              }
          }
  
          void OnToggledEvent(object sender, MyToggledEventArgs args)
          {
              var item = args.MyItem;
              if (item != null)
              {
                  Debug.WriteLine("Userid:>>"+item.userProfileTO.userId);
              }
          }
  
     //Model class
  public class DirectoryResponse
      {
          public List<UserProfileHBList> userProfileHBList { get; set; }
      }
  
      public class UserProfileHBList
      {
          public UserProfileTO userProfileTO { get; set; }
      }
  
      public class UserProfileTO
      {
          public string userId { get; set; }
          public string firstName { get; set; }
          public string email { get; set; }
          public string lastName { get; set; }
      }
  

  Is there any other way to get the userid?

  Hi @seanyda and @AlessandroCaliaro
  Got the id of the selected item by below code:

  In the OnToggledEvent(object sender, EventArgs args) we can get the Parent ViewCell depending on your hierarchy:

  public void OnToggledEvent(object sender, EventArgs args)
  {
      //Here I use a Grid to wrap the content so I need to use two Parent to find the ViewCell
      ViewCell cell = (sender as Switch).Parent.Parent as ViewCell;
  
      // If you set the list<UserProfileHBList> as the ListView's ItemsSource, we can find the model through BindingContext
      UserProfileHBList model = cell.BindingContext as UserProfileHBList;
  
      // Then the userId can be known
      if (model != null)
      {
          Debug.WriteLine("Userid:>>"+model.userProfileTO.userId);
      }
  
  }
