Error with the new Windows update to new version 1809

[Fabio]

Hi,
I get this error:
"Errore CS0266 Non è possibile convertire in modo implicito il tipo 'object' in 'decimal?'. È presente una conversione esplicita. Probabilmente manca un cast. ".

My xaml is:

            <sync:SfNumericTextBox Value="{x:Bind Main.Importo,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                                   Grid.Row="7"
                                   Grid.Column="1"
                                   AllowNull="True"
                                   Margin="0,5,0,0"
                                   Width="150"
                                   HorizontalAlignment="Left"
                                   ParsingMode="Decimal" />

My csharp property is:

        public decimal? Importo
        {
            get => _movimento.Importo;
            set
            {
                if (_movimento.Importo != value)
                {
                    _movimento.Importo = value;
                    onChanged();
                    onChanged(nameof(CanSave));
                }
            }
        }

This issue came with the new WNuovo errore con il nuovo aggiornamento di Windows alla nuova versione 1809indows update to new version 1809.

Hi Fabio, 

 

Greetings, we have analyzed your query and we would like to inform you that this is a framework level problem. While using x:Bind with different type source and target, it will throw this exception. This problem occurs in all version of UWP not only in 1809.  

 

You can resolve this problem by using Binding instead of x:Bind in your application as per the below code snippet.  

 

Code snippet 

  <sync:SfNumericTextBox Value="{Binding Main.Importo,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" 

                                   Grid.Row="7" 

                                   Grid.Column="1" 

                                   AllowNull="True" 

                                   Margin="0,5,0,0" 

                                   Width="150" 

                                   HorizontalAlignment="Left" 

                                   ParsingMode="Decimal" /> 

 

Hope this helps you.  

  

Thanks,

Hi,

today I updated Windows to 1809 version and I updated the destination version of my app to Windows 1809.
Until yesterday I used my app with that xaml and Windows SDK 1803.

Hi Fabio,  

 

Thanks for your update, however this binding problem occurs in all the msdn control like (ContentControl, TextBlock..etc), not only in SfNumericTextBox. Please check the behavior of x:Bind markup extension in below link.
