Usability issues with date picker

1. The user clears the date picker with the Delete key and opens the Calendar. It defaults to 01/01/1900 (the current NullDate) which is virtually useless. The masked edit box behaves similarly when the user begins editing a date picker that is cleared." This behavior is normal - the calendar shows the current value of the RadDateTimePicker. If the value is 01/01/1900 then the calendar would be focused on this value. If you want to change the view of RadCalendar use its FocusedDate property. To get the instance of RadCalendar from RadDateTimePicker you can do the following:

2. To do that, you have to use the MaskType standard type of the mask box. We already have an example of editing such values (short date) in our QSF (Editors\RadMaskedEditBox\First Look).

Q:How to define a mask?:
A:Use the Mask property of the mask box.

You should set the mask to "00/00/0000" to achieve the behavior you are describing. You do not need to explicitly type the parentheses when you have such a mask.

Q:How to change the mask type (Standard, DateTime or Numeric)
A:Use the MaskType property.

Q:How to change the current culture used in the mask box
A:Use the Culture property.

3. As I wrote in another thread: To set the ReadOnly state of the maskededit when the value is NullDate do the following:

Hi guys

We are working with version \lib\RCWF\2020.3.1020.40\

We downloaded and tried to check the attached project 140349 but once checked we noticed that it doesn't work as expected.

If I try to input a date 23/11/2020 we saw that the first number (2) goes to the day section but the second character (3) goes to the month section.

Do yo hace any update about this?.

the code we are checking is next one:

       void TextBoxItem_KeyDown(object sender, KeyEventArgs e)
        {
    

            if ((e.KeyCode >= Keys.D0 && e.KeyCode <= Keys.D9) || (e.KeyCode >= Keys.NumPad0 && e.KeyCode <= Keys.NumPad9) || e.KeyCode == Keys.Decimal)
           {
                RadTextBoxItem item = sender as RadTextBoxItem;
                RadMaskedEditBoxElement element = item.Parent as RadMaskedEditBoxElement;
                MaskDateTimeProvider provider = element.Provider as MaskDateTimeProvider;
               
                switch (provider.List[provider.SelectedItemIndex].type)
                {
                    case PartTypes.Day:
                        day++;
                        break;
                    case PartTypes.Month:
                        month++;
                        break;
                }

                if (day == 2)
                {
                    int i = e.KeyValue; 
                    provider.SelectNextEditableItem();
                    day = 0;

                }
                if (month == 2)
                {
                    provider.SelectNextEditableItem();
                    month = 0;
                }
            }
            else if (e.KeyData == Keys.Left || e.KeyData == Keys.Right || e.KeyData == Keys.Divide)
            {
                day = 0;
                month = 0;
            }
        }

However, according to the provided code snippet in your post, if the day is "2", the next part is selected which is the month:

                if (day == 2)
                {
                    int i = e.KeyValue; 
                    provider.SelectNextEditableItem();
                    day = 0;

                }

That is why you observed the mentioned behavior.

I would like to note that in R2 2014 we introduced free form date parsing implemented by a new MaskType for RadMaskedEditBox. It is designed to work with DateTime objects and it is not format restricted. With the new MaskType the input string is parsed to valid DateTime object

https://docs.telerik.com/devtools/winforms/controls/editors/datetimepicker/free-form-date-time-parsing 

I think that it may be more appropriate for your scenario. If you need any further assistance please don't hesitate to contact me.
