[RESOLVED] Data Bindings - Invalid cast exception with DBNulls

Hello,

I'm binding a ComboBox's SelectedIndex to a Nullable database field like so:

VB.NET Code:

ColapsoComboBox.DataBindings.Add("SelectedIndex", EnsaiosBindingSource, "Colapso", False, DataSourceUpdateMode.OnValidation, 0)

As you can see, I've defined the NullValue to be zero, yet I get an InvalidCastException.
Is there anything I'm doing wrong? Or is handling the binding's Format and Parse events the only way around this?

Thanks in advance

Anyone?

I've fixed it by setting formattingEnabled to True.
