Label ContentStringFormat

Why StringFormat on a WPF Label’s binding does nothing, and the property that does.

Again this morning struggled with something I knew I had struggled with before this time I am in WPF XAML trying to set a StringFormat on my binding to get it formatted as a 2 decimal:

<Label Content="{Binding SelectedObject.DoubleNumber, StringFormat=N2}"/>

Running my view it is not showing me what I want to see; in this case showing 17.877651246, then I suddenly remembered that the Label control has its own way of dealing with StringFormat with the ContentStringFormat property:

<Label ContentStringFormat="N2" Content="{Binding SelectedObject.DoubleNumber}" />

The view is giving me 17.88 awesome!

I hope I remember this now actually makes a bit sense; I am setting the Content so setting the Content => StringFormat .. aah
