Get the unselected items from sfListView

[pumaprog]

Hello!  I have a program that contains an sfListView.  It has an event OnSelectionChanged that runs some code and changes the visuals of a cell when a cell is tapped.  It then marks the cell as selected.  I can then call all of the selected cells and place them into a List<T> by calling listView.SelectedItems.  Is there a good solution for getting the items that were NOT selected?

Hi Tommy,   

   

Thank you for using Syncfusion Products.   

   

The reported requirement “Get unselected items in SfListView” can be achieved by a workaround in sample level. In the sample, you can filter the SelectedItems and unselected items from the underlying collection like below code example.   

   

Code Example[C#]:   

private void listView_SelectionChanged(object sender, ItemSelectionChangedEventArgs e)   

{   

  var unselecteditems = new List<Contacts>();   

  var selecteditems = new List<Contacts>();   

  for (int i = 0; i < viewModel.contactsinfo.Count; i++)   

  {   

    var item = viewModel.contactsinfo[i];   

    if (listView.SelectedItems.Contains(item))   

        selecteditems.Add(item);   

    else   

        unselecteditems.Add(item);   

  }   

}   

  

    

Please let us know if you require further assistance.
