Hello,
I am using Telerik RadControlls for WPF Q3 2009.
I have RadNumericUpDown defined in xaml as follows:
<Telerik:RadNumericUpDown Height="25" Width="100" CustomUnit="kg" Minimum="0" Maximum="250" ValueFormat="Numeric" NullValue="N/A" IsInteger="True" Value="{Binding Path=Weight, Mode=TwoWay}"/>
I am binding the value to property on my ViewModel class. The property is of ?float type. It returns float or null. When it returns float number, the NumericUpDown works fine. But when the property returns null, the NumericUpDown displays "0 kg" instead of "N/A". It is impornant for my application to distinguish between 0 and null, but the NumericUpDown seems to fail at this.
Is this bug or am I missing something?
Thanks
Lukas
