This is a weird bug, but our QA team noticed that quickly typing A LOT of letters (with numbers in between them) into a NumericUpDown box, freezes the UI (and it never goes back). The NumericUpDown is directly bound to VM and we are not using any converters or code behind. We are using noXaml dlls.

 

XAML

 

<telerik:RadNumericUpDown HorizontalAlignment="Stretch"
AutomationProperties.AutomationId="FindSiteBasePortNumericUpDown"
Maximum="65534"
Minimum="1"
Value="{Binding Port, Mode=TwoWay}"
IsEnabled="{Binding IsFormIdle}"/>

VM:

public Decimal Port
{
get { return m_port; }
set { SetValue_(ref m_port, value, () => Port); }
}

Hello Tulio,

Thank you for the provided xaml. 

I tested the described behavior on my end, however I am afraid that I was not able to reproduce it. This is why I am attaching the sample project, which I used for testing purposes. Please, check it out and let me know, if I am missing something. May I kindly ask you to modify the sample project in order to reproduce the faulty behavior and send it back in a new support ticket? You can also share some sample steps or a video, which I can use in order to reproduce the same result on my end.

If you are able to reproduce the same behavior with the sample project, can you elaborate on the exact setup on your end? Can you share which version of the UI for WPF dlls you are using? May I ask you to specify, if you are using different application cultures? Additionally, can you specify, if you are testing on a touch monitor?

Thank you in advance for any help you can provide.

Regards,
Vladimir Stoyanov
