WPF Datagrid DataGridTextColumn does not allow decimal

问题

I am not able to enter decimal values in DataGridTextColumn. Below link suggest that we cannot enter decimal values if UpdateSourceTrigger = PropertyChanged.

WPF DataGridTextColumn binding doesn't accept decimals

But my requirement is that I have to keep UpdateSourceTrigger = PropertyChanged.

Please suggest.

Below is the code snippet for my Datagrid:

  <DataGrid x:Name="MyDataGrid" HorizontalAlignment="Left" CanUserResizeColumns="True" VerticalAlignment="Stretch" ItemsSource="{Binding MyDataCollectionListView, Mode=TwoWay}"
      SelectionMode="Extended" IsSynchronizedWithCurrentItem="True" SelectionUnit="Cell">                                                      
     <DataGrid.Columns>
      <DataGridTextColumn x:Name="ColMyDataGrid" Header="Price" Binding="{Binding Path=Price, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged, Converter={StaticResource    ZeroToEmptyConverter}}" >
  <DataGridTextColumn.ElementStyle>
    <Style TargetType="TextBlock">
      <Setter Property="TextAlignment" Value="Right" />                                               
       <Setter Property="Background" Value="#BEFAC4"/>   
    </Style>
  </DataGridTextColumn.ElementStyle>
 </DataGridTextColumn>
</DataGrid.Columns>
