DataGrid - wrong number when entering a decimal in datagrid when using NumericTextBox or DoubleTextBox

Hello,

I found that if I use for the property FocusChangedBehaviorProperty the value "Round" for the NumericTextBox and the DoubleTextBox and enter a decimal followed by a number it gives the wrong number.

See below for how to reproduce it.

To see the problem click on the first cell of column "FirstName". Then click tab until the cell in the Weight column is highlighted. The value you should see is 183.

Then click the decimal key and then click the number two key and you should see 1,283.

This does not occur If we remove FocusChangedBehavior="Round" from the DataTemplate.

Thank you

Oscar

To reproduce I used your sample "DataGridCustomEditorsDemo" and did the following.

1) in file DataGridCustomEditorsDemo.xaml add DataTemplate and column editor for Weight property.

    <DataTemplate x:Key="WeightTemplateEditor">
        <Border Background="White">
            <ms:NumericTextBox Value="{Binding Weight, UpdateSourceTrigger=LostFocus}" RangeConstraintMode="OnLostFocus" FocusChangedBehavior="Round"
                               HorizontalAlignment="Stretch" TextAlignment="Right"/>
        </Border>
    </DataTemplate>

    <ms:DataGridColumn PropertyName="Weight" EditorTemplate="{StaticResource WeightTemplateEditor}"/>  

2) In file SimplePerson.cs added new float property Weight to SimplePerson class.

private float _weight;

[Description("How much a person weighs.")]
public float Weight
{
   get { return _weight; }
   set
   {

      Set(ref _weight, value, "Weight");
   }
}

3) Modified constructor in DataGridCustomEditorsDemo.xaml.cs to add the Weight values

 for (int i = 0; i < 9; i++)
      {
         people.Add(new SimplePerson { FirstName = "Alice", Surname = "Turing", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
        people.Add(new SimplePerson { FirstName = "Bob", Surname = "Schneier", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
        people.Add(new SimplePerson { FirstName = "Carol", Surname = "Carpenter", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
        people.Add(new SimplePerson { FirstName = "Dickie", Surname = "Davies", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
        people.Add(new SimplePerson { FirstName = "Ernesto", Surname = "Egregious", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
        people.Add(new SimplePerson { FirstName = "Fangus", Surname = "Follies", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
        people.Add(new SimplePerson { FirstName = "Gerald", Surname = "Gryptype-Thynne", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
        people.Add(new SimplePerson { FirstName = "Hilary", Surname = "Harbuckle", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183  });
        people.Add(new SimplePerson { FirstName = "Iona", Surname = "Impetigo", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
        people.Add(new SimplePerson { FirstName = "Janet", Surname = "Jollity-Farm", Age = random.Next(10, 100), Height = random.Next(80, 180), Weight = 183 });
      }

Hi Oscar,

Thanks for pointing this out and providing the repro steps. A fix for this issue will be available in the next nightly build.
