Updating Binding doesn't update control if control has focus

[Alan]

While the RadNumericUpDown control still has the focus from a previous edit,
if I update what it is bound to in code behind and RaisePropertyChanged for the property,
the RadNumericUpDown does not get updated.

If I first take the focus off of RadNumericUpDown on to another control before changing the bound value in the same way
as above the same RadNumericUpDown does get updated.

Some questions:
  * Is this behavour expected?
  * How can I disable/workaround this?

Below is how I am defining the control and binding in XAML:

<controls:RadNumericUpDown x:Name="XTextBox" Value="{Binding GraphicalItem.Rect.X}" UpdateValueEvent="PropertyChanged" Minimum="{Binding GraphicalItem.Rect.MinX}" Maximum="{Binding GraphicalItem.Rect.MaxX}" LargeChange="{Binding LargeCoordinateChange}" SmallChange="{Binding SmallCoordinateChange}" BorderBrush="#FFCBCBCB" Margin="3,2,0,2" HorizontalAlignment="Right" BorderThickness="1" Background="{x:Null}" Height="20" MinWidth="40" Padding="1,1,2,1"/>

Hi Alan,

You mean that the ValueChanged event is not fired?
I have tested in a simple project, in which on a Timer tick I am updating the property bound to the Numeric's value, and it works as expected: the value is updating and the ValueChanged event i fired, but the text is not updated until it looses focus.
Could you please send us a sample project, where this issue can be reproduced? In that way we will be able to debug it locally and find the source of the problem.

Looking forward to your reply.

Kind regards,

I wanted the text to update, even when focus was still on control.
I noticed that you have already given an answer and fix to this here:

I tried this and it works for me.
Issue closed!

Thanks,
