Question

I’m using scientific notation in XAML. I do:

<TextBox Text="{Binding Path=CELULARIDAD_CFU, StringFormat='e6'}"/>

The problem is that for 1710000 is showing: 1.710000e+006, which is correct but I would like to see 1.71e+6. How is this specified in XAML? (Not in code)

Answer 1

I didn’t found exactly what I want so I decided to use an IValueConverter. Example:

Public Class scientificNotation6
    Implements IValueConverter

    Const EXP As Double = 1000000
    Public Function Convert(value As Object, targetType As System.Type, parameter As Object, culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert
        Return CDbl(value) / EXP 'whatever you want
    End Function

    Public Function ConvertBack(value As Object, targetType As System.Type, parameter As Object, culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.ConvertBack
        Return CDbl(value) * EXP 'whatever you want
    End Function
End Class

And then in the XAML page:

<TextBox Text="{Binding Path=CELULARIDAD_CONGELADO, Converter={StaticResource scientificNotation6}"/>

I hope it helps.
