Why I cannot add text after lost focus in NumericUpDown of MahApp in C# WPF

I’m using C# WPF and MahApps Controls

I set a string format for Thousands separated like : #,### in NumericUpDown it’s working when I typing number in that but when I lost focus of my NumericUpDown , I cannot add text end of it or between it ! I have to clear all of value in my NumericUpDown and that I can add text again

My XAML :

<Window
        
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:mah="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
        xmlns:local="clr-namespace:WpfApp8"
        xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit" x:Class="WpfApp8.MainWindow"
        
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">

    <Grid>
        <mah:NumericUpDown Name="txtnumer"  HorizontalAlignment="Left" Margin="443,256,0,0" VerticalAlignment="Top" Height="41" Width="264" ParsingNumberStyle="Number" Culture="fa-IR" SnapToMultipleOfInterval="True" Value="0" ChangeValueOnTextChanged="True" Minimum="0" Interval="1" NumericInputMode="Decimal" Speedup="False" StringFormat="#,###"/>


    </Grid>
</Window>

Hi @mojtabahakimian

as this is a free-time project, it will be fixed when there is enough free time. Normally Jan is keeping an eye on the more annoying bugs 😄 .

Thank you for your patience & happy coding Tim
