Hi Pavel,

I am unable to replicate the exact behaviour in the sense that on initial load in my project, the dataform does adhere to the current ui culture as set by the following code in the MainPage.xaml.cs:

Thread.CurrentThread.CurrentCulture = new CultureInfo("de");

Thread.CurrentThread.CurrentUICulture = new CultureInfo("de");

And by using the following line to force the xaml page to use the necessary settings:

Language = XmlLanguage.GetLanguage(Thread.CurrentThread.CurrentCulture.Name);

I am also setting the necessary Resource Manager:

LocalizationManager.Manager = new LocalizationManager

{

ResourceManager = Strings.ResourceManager

};

However, whilst this works for the one project, I cannot replicate it in the smaller test solution where the data is shown in US format no matter what I do.

In the original project, I get the correct format initially but this defaults to US as soon as I click edit. I have noticed that if I use the DateField control, proper format is shown, it i only when I I use the standard datafield:

<telerik:RadDataForm

    x:Name="entityForm"

    CurrentItem="{Binding CurrentEntity}"

    ItemsSource="{Binding ItemCollection}"

    CommandButtonsVisibility="Edit,Delete,Commit,Cancel"

    AutoGenerateFields="False">

  <telerik:RadDataForm.ReadOnlyTemplate>

      <DataTemplate>

          <StackPanel>

            <telerik:DataFormDataField DataMemberBinding="{Binding StartDate, Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property1}" IsReadOnly="True" />

            <!-- Display only US format -->
            <telerik:DataFormDateField DataMemberBinding="{Binding EndDate, StringFormat='\{0:d\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property2}" IsReadOnly="True" />

            <!-- US Decimal point shown -->
            <telerik:DataFormDataField DataMemberBinding="{Binding VAT, StringFormat='\{0:F2\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property3}" IsReadOnly="True" />

            <!- USD sign and decimal point shown -->
            <telerik:DataFormDataField DataMemberBinding="{Binding Price, StringFormat='\{0:c\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property4}" IsReadOnly="True" />

          </StackPanel>

      </DataTemplate>

  </telerik:RadDataForm.ReadOnlyTemplate>

  <telerik:RadDataForm.EditTemplate>

      <DataTemplate>

         <StackPanel>

          <telerik:DataFormDateField DataMemberBinding="{Binding StartDate, StringFormat='\{0:d\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property1}"/>

          <telerik:DataFormDateField DataMemberBinding="{Binding EndDate, StringFormat='\{0:d\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property2}" />

          <telerik:DataFormDataField DataMemberBinding="{Binding VAT,StringFormat='\{0:F2\}',  Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property3}" />

          <telerik:DataFormDataField DataMemberBinding="{Binding Price, StringFormat='\{0:c\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property4}" />

         </StackPanel>

      </DataTemplate>

  </telerik:RadDataForm.EditTemplate>

</telerik:RadDataForm>

Any pointers would be much appreciated.

Kind Regards

Hi Pavel,

Thanks for looking into this. Perhaps you can confirm a couple of things regarding expected behaviour?

1. Using the the DataFormDataField control, you would expect any StringFormat such as {0:c}, {0:d}, {0:F2} etc to adhere to the Current UICulture if set in either the App.xaml.cs or MainPage.xaml.cs (i.e. Thread.Currentthread.CurrentUICulture = new CultureInfo("de");)

2. Within the Validation Summary, the Message Header of a ValidationSummaryItem *cannot* be changed - it appears to always be the name of the Property (whereas the Label or ErrorMessage can be controlled using the Display and Requried DataAnnotation attribues)

Kind Regards

Hello Ben,

1. Using the the DataFormDataField control, you would expect any StringFormat such as {0:c}, {0:d}, {0:F2} etc to adhere to the Current UICulture if set in either the App.xaml.cs or MainPage.xaml.cs (i.e. Thread.Currentthread.CurrentUICulture = new CultureInfo("de");)

RadDataForm would do nothing different than the standard MS controls. It relies on bindings and does not do any special handling for the current culture. In other words it will show exactly the same result as would a stand alone TextBlock with format string in the binding.
In other words :

<telerik:DataFormDataField DataMemberBinding="{Binding Price,StringFormat=\{0:C2\}}"/>

and a standalone text box(w/o a DataForm) like :

<TextBlock Text="{Binding Price,StringFormat=\{0:C2\}}" />
Are expected to show exactly the same result.

2. Within the Validation Summary, the Message Header of a ValidationSummaryItem *cannot* be changed - it appears to always be the name of the Property (whereas the Label or ErrorMessage can be controlled using the Display and Requried DataAnnotation attribues)

With the current version the "Header" is taken form the field label . Whenever there is no field it falls back to the Path of the Binding.

Hi Pavel,

Thanks for clarifying these points, however, I can consistently reproduce contradictory results, even without setting the Current UI Culture, as you will see with the attached images. I have declared the following in the readonly template of a dataform:

<TextBlock Text="{Binding StartDate, StringFormat=\{0:d\}}" />       
<TextBlock Text="{Binding Price, StringFormat=\{0:F2\}}" />       
<TextBlock Text="{Binding VAT, StringFormat=\{0:c\}}" />
<telerik:DataFormDateField DataMemberBinding="{Binding StartDate, StringFormat='\{0:d\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property1}" IsReadOnly="True" />       
<telerik:DataFormDataField DataMemberBinding="{Binding EndDate, StringFormat='\{0:d\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property2}" IsReadOnly="True" />       
<telerik:DataFormDataField DataMemberBinding="{Binding VAT, StringFormat='\{0:F2\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property3}" IsReadOnly="True" />  
<telerik:DataFormDataField DataMemberBinding="{Binding Price, StringFormat='\{0:c\}', Mode=TwoWay}" Label="{Binding Source={StaticResource StringResources}, Path=StringsResources.Property4}" IsReadOnly="True" />  

The captured image shows that the textblocks do indeeed, as you suggest, 

conform to my current ui culture (en-GB). 

However the DataFormDataFields revert to en-US format.

As for validation, the second captured image shows that when the Price fails validation, 

the message header is "Price" (in red), which is the name of the property. 

The Display Name of the Property is used in the description and the 

dataform field label is used in the dataform but neither are used within the message header.

This again goes against what you are suggesting.


Any ideas?



Kind Regards



Ben
