NumericTextBoxDouble Binding Initial Value

[jtamaska]

Hi,

I have a ni:NumericTextBoxDouble binded OneWayToSource to a Property. How do I set the Initial Value, which is show (an set) by starting up my program? Now it is showing 0.00.

<ni:NumericTextBoxDouble 
x:Name="YMax" 
Value="{Binding Path=MyYMax, Mode=OneWayToSource, ValidatesOnExceptions=True }" 
InteractionMode="ArrowKeys, ScrollWheel, TextInput" 
Width="58" 
Margin="0,10" 
Cursor="IBeam">
                    <ni:NumericTextBoxDouble.ValueFormatter>
                        <ni:GeneralValueFormatter  Format="0.00" ShortFormat="{x:Null}"/>
                    </ni:NumericTextBoxDouble.ValueFormatter>
</ni:NumericTextBoxDouble>

I believe you can set FallbackValue to get a default value when using a OneWayToSource binding.

ni:NumericTextBoxDouble doesn't seem to have a FallbackValue property...

I solved the Issue with the following Workaround:

I set the Binding type to TwoWay, and gave the Property to a default value. It works, but not a perfect model of my data handling.

To clarify, I meant the FallbackValue property on Binding itself:

    <ni:NumericTextBoxDouble Value="{Binding Path=MyYMax, Mode=OneWayToSource, ValidatesOnExceptions=True, FallbackValue=1.1}" ...

I didn't think of that 😞 That solves it! Thank you!
