NumericUpDown didn't update when lost focus, StringFormat has no effect to the content string

NumericUpDown didn't update

I‘ve wrote an simple solution to demonstrate this issue download code.

Value of NumericUpDown(NUD) was bonded to the field of Model class
-public float Age { set; get; }
And the StringFormat of NUD was set as
-StringFormat="{}{0:N6} ms"

if one typed something like "9.87654321" and tab to another control, the content of NUD will still be "9.87654321", not the exact one "9.876543 ms"

The thing is quirk because the NUD used in the offical demo solution (right-bottom in the Text tab) present well. If you input "9.87654321" and then change the focus, the content of NUD will update as expected immediately.

Environment

• MahApps.Metro v1.5.0
• Windows OS win7 x64
• Visual Studio 2015
• .NET Framework 4.5
• Reference SoftFluent.Windows

@ShannonZ I can not reproduce this with the v1.5.0 of MahApps.

just type more digits to call up the Horizotal Scrollbar of NUD.

@ShannonZ I can not reproduce this with the v1.5.0 of MahApps.

I have done this experiment in another two computers with VS2015 installed, but the problem is still exist.
Is is possible to relate with cultureinfo?

@ShannonZ where/what is the code of this?

[ShannonZ]

@punker76 The solution attached in the first floor has the same problem.
Solution

[punker76]

@ShannonZ In this sample you set StringFormat="0" if I set it to StringFormat="{}{0:N6} ms" it works for me™.

[ShannonZ]

@punker76 Have you input enough digits? Have you seen the horizontal scrollbar?

The new

How to update the content of NUD programmatically?

[punker76]

@ShannonZ to hide the scrollbars do this on your NumericUpDown

ScrollViewer.HorizontalScrollBarVisibility="Hidden"
ScrollViewer.VerticalScrollBarVisibility="Hidden"

[punker76]

@ShannonZ íf there is no other tabable control the tab doesn't work

[ShannonZ]

Can the problem be reproduce at your computer?
In my office, only if inputting excessive precision the content of NUD won't be update any more.
But the button(+/-) can work perfectly. Is it possible to call the Click callback of + programtocally? Succeeding with a calling of Click callback of -.

@ShannonZ I'm investigating what's wrong with this

[ShannonZ]

@punker76 Has it been fixed？

[ShannonZ]

@punker76 Is there any temporary solution?
Sorry to disturb you so frequently but I myself cannot solve it.

[punker76]

@ShannonZ Should be fixed now with bd5b84f, available in 1.6.0 (and upcoming alpha)
