Hi Dinko,

Hi Patrick,

Thank you for your patience.

I think the problem comes from the fact that the RadGridView does not respect the CurrentCulture Format settings when formatting its data. You can read more about this behavior in the CurrentCulture Format Settings are not respected troubleshooting article. The tricky part here is how to set it to the RadGridView in the details view as the file dialogs do not expose an API to directly customized it. You will need to create an attached property in which you can subscribe to the RadComboBox(layout configurator) SelectionChanged event. In the event handler, you can check what is the current view. If it is a details view, you can search for the grid and set the IsLocalizationLanguageRespected property to false.

The attached project demonstrates this approach. Can you give it a try on your side and let me know how it goes.

Regards,

Hi Dinko,

I really think that the Telerik file dialogs should provide this functionnality "out-of-the-box".

For attaching an event to the layout configurator changed, I've done it in my code to save/load the user settings for the dialog (a complicated thing because Telerik doesn't provide it and accesses to the controls is difficult).

Your solution doesn't work because the GridView is not created when the SelectionChanged event is fired. I had to code it this way:

If LayoutConfigurationModel (Args.NewValue):LayoutType = LayoutType.Details Then

Dlg.Dispatcher.BeginInvoke ( // waits for Telerik to put the grid view into place

DispatcherPriority.ApplicationIdle,

->

Begin

DetailsGridView := Dlg.FindChild <RadGridView> (Name_DetailsPane);

...

End)

A simple Dispatcher.BeginInvoke doesn't work when the layout is changed using Ctrl+MouseWheel (a lot of code to implement this correctly). Adding DispatcherPriority.ApplicationIdle seems to work in all cases.

Hi Patrick,

Thank you for the provided images.

After running a few tests on my side, I was able to reproduce this behavior. It turns out the date format is not applied correctly initially. If you, for example, navigate to a folder after you have loaded the details view, the format is shown correctly. To workaround this, you can call the Rebind() method of the RadGridView after setting the IsLocalizationLanguageRespected to false.

private static void ComboBox_SelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e)
{
    if (e.AddedItems.Count > 0)
    {
        if ((e.AddedItems[0] as LayoutConfigurationModel).NameKey == "FileDialogs_Details")
        {
            Application.Current.Dispatcher.BeginInvoke((Action)(() => {

                RadGridView gridView = FileDialog.ChildrenOfType<RadGridView>().FirstOrDefault();
                gridView.IsLocalizationLanguageRespected = false;                        
                gridView.Rebind();
            }));
        }
    }
}

In addition: The DispatcherPriority is not necessary in this case, at least on my side.
