WPF DatePicker dateformat change issue

Question

Hi ,

i have used a datepicker inside my code .
I want the format as dd/MM/yyyy but i am getting it always as MM/dd/yyyy.
Here is the snippet for the datepicker code.
Can anyone help please.
<DatePicker Name="dateTimePicker1" Grid.Row="2" Grid.Column="3" Margin="0,0,57,0" ToolTip="{Binding Mode=TwoWay,Path=.}"
SelectedDate="{x:Static s:DateTime.Now}" SelectedDateChanged="dateTimePicker1_SelectedDateChanged"
materialDesign:HintAssist.Hint="Pick Date"
Foreground="Black" VerticalAlignment="Bottom" >
<DatePicker.Resources>
<Style TargetType="DatePickerTextBox" >
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>

                                                    <TextBox x:Name="DP_TextBox" Text="{Binding Path=SelectedDate,StringFormat={}{0:dd/MM/yyyy},RelativeSource={RelativeSource AncestorType={x:Type DatePicker}}}"/>
                                                </ControlTemplate>
                                            </Setter.Value>
                                        </Setter>

                                    </Style>
                                </DatePicker.Resources>





                            </DatePicker>

Thanks

You may be not able to set the format of DatePicker SelectedDate to dd/MM/yyyy in xaml , I tested as below and it showed an error.

There is a description A date that is in one of the formats that are listed in the DateTime XAML Syntax topic. in the document DatePicker.SelectedDate Property XAML Values part. (DateTime XAML Syntax)

You can use below method to update format in C# code:

Method 1:

var txt = this.dateTimePicker1.SelectedDate.Value.Date.ToString("dd/MM/yyyy")  

Method 2:

CultureInfo ci = CultureInfo.CreateSpecificCulture(CultureInfo.CurrentCulture.Name);  
            ci.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";  
            Thread.CurrentThread.CurrentCulture = ci;  
  
            var txt = this.dateTimePicker1.SelectedDate.Value.Date.ToShortDateString();
