I need more information.

Would you mind telling me exactly what would you like to invert? I have no exact clue now, what you would you like to have. Thx in advance.

Hi,

Here is the code i have used in my application.

Here i need to unselect the selected items and select the unselected item in a button click which means i need to invert the selected items in a list view.

// Storing the selected items in an int List

 List<int> _intList = new List<int>();
 for (int k = 0; k < MyListView.SelectedItems.Count; k++)
    _intList.Add(MyListView.Items.IndexOf(MyListView.SelectedItems[k]));

// Clearing the selected items

 MyListView.SelectedItems.Clear(); 

// Inverting
 for (int i = 0; i < MyListView.Items.Count; i++)
 {
 if (!_intList.Contains(i))
                    MyListView.SelectedItems.Add(MyListView.Items[i]);
}
