Question: I am just wondering is it possible to do something like this:

```
private int _x;
public int X 
{
get{ return _x;}
set{_x = value; OnPropertyChanged(*theNameOfTheProperty*);}
}

```

without actually specifying `OnPropertyChanged("X");`

I guess making `OnPropertyChanged` more generic maybe using reflection...

Answer: 
There are two ways to *sort of* do what you are asking. The first (.NET 4.5+ only!) way to do it is to modify OnPropertyChanged to:

```
private void OnPropertyChanged([CallerMemberName] string propertyName = "")
{
 ....
}

```

Then you call it from the setter:

```
set
{
   _var = value;
   OnPropertyChanged();
}

```

This will automatically populate the "propertyName" argument with the calling property, unless you provide the argument explicitly. Note you need a `using System.Runtime.CompilerServices;` to get the namespace for the `CallerMemberName` attribute.

The other way would be to write a custom version of the `propfull` snippet to populate it for you at creation time. My version of this snippet is:

        set 
        {

            OnPropertyChanged($property$);
        }
    }
    $end$]]>
            </Code>
        </Snippet>
    </CodeSnippet>

You can declare your `OnPropertyChanged` this way:

```
    protected void OnPropertyChanged([CallerMemberName] string name = "")
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(name));
        }
    }

```

Then you can invoke it like that from the property:

```
    public IEnumerable<Customer> Customers
    {
        get
        {
            return this.customers;
        }
        set
        {
            this.customers = value;
            this.OnPropertyChanged();
        }
    }

```
