I am not able show the current time for the winform dattimepicker control in WPF.It shows default time.

If use the dame peiece of code in winform load it will show the current time.I dont understand what went wrong

can you please let me know what was wrong with it.

xaml:

<Grid Grid.Row="6" Name="gdCheckIn"  Height="20" HorizontalAlignment="Left"  VerticalAlignment="Center" Width="200" Margin="140,0,0,0">
                                                   <WindowsFormsHost>
                                                       <wf:DateTimePicker x:Name="dtprom" ValueChanged="dtprom_SelectedDateChanged"/>
                                               </WindowsFormsHost>
                                               </Grid>

code on windows load:

dtprom.Format = System.Windows.Forms.DateTimePickerFormat.Custom;
            dtprom.CustomFormat = "dd-MM-yyyy hh:mm";

I don't get any error or exception but i xaml where ever added the above xaml code,at that control if i hover on it,shows "cannot register duplicate name "dtprom" in this scope".

If i execute the same code in a new project it shows with todays Date and Current time.How can i solve it.Any idea.
