First, I insert a date with control "datepicker", then when I want to modify some data I dont want to change the date it will change automatically to the default value which is 01/01/1990 00:00:00.

Problem is that I don't want to display the time only date.

1.

CultureInfo newCulture = (CultureInfo)Thread.CurrentThread.CurrentCulture.Clone();
newCulture.DateTimeFormat.ShortDatePattern = "dd/MM/yyyy";
newCulture.DateTimeFormat.DateSeparator = "/";
Thread.CurrentThread.CurrentCulture = newCulture;

2.

DateTime myDate = new DateTime();
   string us = myDate.ToString(new CultureInfo("en-US"));

Since you're a newbie you first need to understand what a DateTime object is and what a date time picker object would return to you, it is a string not a DateTime.

You need to convert it to the DateTime object and then you can do the DateTime maths on it.

| in the first time I insert a date with control "datepicker",

for that you need to get a date time picker object, and pass a valid string to it or select from the UI provided.

| in the second time when i want to modify some data and i dont want to change the date it will change automatically to the default value which is 01/01/1990 00:00:00

To change it automatically, you can simply just create a new instance, and it will go back to the Min value of the DateTime, like this

C#

DateTime dateTime = new DateTime(); // there you go!

Once done, you can get the Date part using a built-in function like

C#

MessageBox.Show(dateTime.ToLongDateString());

It will show you with the date part of the dateTime object only.

I have written an article about the DateTime object and how you can use it in WPF, Understanding DateTime struct in .NET Framework (using C#)[^] feel free to read it and ask question if help needed! :-) Good luck.
