New Post: DataGrid DateTime Localization

Okay i found a problem...

<xcdg:Column Title="Departure" FieldName="Departure" DisplayMemberBinding="{Binding Departure}"

                                 CellHorizontalContentAlignment="Center" CellVerticalContentAlignment="Center">
                        <xcdg:Column.CellContentTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding StringFormat=d}" />
                            </DataTemplate>
                        </xcdg:Column.CellContentTemplate>
                    </xcdg:Column>

If I use the CellContent and i only want to show the date with StringFormat=d the localization doesnt work. If i remove the CellContentTemplate it works. But since the DisplayMemberBinding ignores the StringFormat I have to do it this way.

But how can i get the localization to work?
