Wrong DateTime Localization since 2012 Q2 SP2

[Denny]

Hello,

since 2012 Q2 SP2 the RadGridView shows the DateTime Values in en-US culture.
How can I change the the culture back into the machine culture?

Hello,

This behaviour is due to the fact that now the culture used is the one specified as a Language for the containing Window.
You should set the Language property like so (to have the machine culture applied): 

public MainWindow()
{
            InitializeComponent();
            this.Language = XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag);
...
}

Kind regards,

I am glad that you provided a solution in this thread.
Nevertheless it has cost me some time to find it.

As I saw in the forum, this has been a breaking change for many of us developers, so I wonder why this was not marked as such in the release notes.

It would be nice if you note such changes in the release notes

Hi,

You are right that we would mark this better in the Release Notes. Currently we have stated those two lines here:
-> Changing Language property is not respected. 
-> Language property of the parent FrameworkElement is not respected. Changing Language property is not respected. 

The documentation will be updated soon with this information as well.

Hello,

In addition to my last answer, I would like to inform you that we have introduced a new property IsLocalizationLanguageRespected of the RadGridView. It is available in our latest internal build. 

Its default value is 'true' meaning that the formatting will be based on the Language property (default behaviour). Once you set it to 'false", then the CurrentCulture will be respected.
