Comments: ** Comment from web user: nickgrishaev **
The step needed to reproduce this bug: create empty WPF application (use .Net 4.5), add Wpf Extended Toolkit (v. 2.4) using NuGet.
Add DateTimePicker to the form:
```
<Window x:Class="WPFtest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:toolkit="http://schemas.xceed.com/wpf/xaml/toolkit"
Title="MainWindow" Height="350" Width="525">
<Grid>
<toolkit:DateTimePicker CultureInfo="(Default)" FormatString="g"
Format="Custom" Height="21" Width="200"/>
</Grid>
</Window>
```
Start application and in DateTimePicker box type 22. (two two point), application crushed after . (point) entered in the box. If you type only 22 without . (point) – application does not crashed.
I think this bug depend on system regional setting.
My system regional settings attached.
This is call stack of test application:
```
System.FormatException was unhandled
HResult=-2146233033
Message=String was not recognized as a valid DateTime.
