I need to hold the selected ListView Item in a temporary variable.

Question

I need to hold the selected ListView Item in a temporary variable so that the user can Cancel an Edit operation and the ListView Item will revert back to its original values. I can't understand why Temporaryselectedudf changes to the SelectedUdf value. Thanks !

Model
public class UserDefinedFields : INotifyPropertyChanged 
{ protected bool doOnChange; 	
  private int _id; 	
  private string _name;
....

View Model
[ObservableProperty] 	
UserDefinedFields _selectedUdf;
....

var tmp = new UserDefinedFields(); 		
tmp=SelectedUdf; 		
Temporaryselectedudf = tmp;

Answer 1

that's because class instance assign is by ref, not a copy:

public class MyClass
{ 
    public int Value;
}

var a = new MyClass { Value = 1};
var b = a;  // b points to the same instance as a
Console.WriteLine(a.Value); // 1
b.Value = 2;
Console.WriteLine(a.Value); // 2 

so in your case store the items values in a variable(s), and restore
