DateTimePicker how change the month and week name ?

[Qakmak]

I want to change the month name and week name, for Localization.

but I can't use Culture feature. because that language not in microsoft CultureInfo.

so I need Custom change the name value .

How can I do?

[Qakmak]

before I'm using one component can doing this. like:

//set the months name
this.dtpTime.FormatProvider.MonthNames = new[] { "one", "two", "three", "4", "5", "6", "7", "8", "9", "10", "11", "12", "" };
//set the weeks short name
//this.dtpTime.FormatProvider.ShortestDayNames = new[] { "ي", "د", "س", "چ", "پ", "ج", "ش" };


use this can change the weeks and months name. 
This can be set independently It, Does not depend on CultureInfo.


Or better way is can implement some localization interface in your api.

Hi Qakmak,

Thank you for writing.

RadDateTimePicker uses a CultureInfo object to localize the dates it displays. The same applies for the RadCalendar that the date time picker hosts. You can create a custom culture info with your desired day and month names and use it in the RadDateTimePicker. Here is an example:

try
{
    CultureInfo c = new CultureInfo("my-MY");
    CultureAndRegionInfoBuilder.Unregister("my-MY");
}
catch { }

RadDateTimePickerCalendar calendar = this.radDateTimePicker1.DateTimePickerElement.CurrentBehavior as RadDateTimePickerCalendar;
CultureAndRegionInfoBuilder buidler = new CultureAndRegionInfoBuilder("my-MY", CultureAndRegionModifiers.None);
buidler.LoadDataFromCultureInfo(calendar.Calendar.Culture);
buidler.LoadDataFromRegionInfo(new RegionInfo(calendar.Calendar.Culture.Name));
buidler.GregorianDateTimeFormat.DayNames = new string[] { "ي", "د", "س", "چ", "پ", "ج", "ش" };
buidler.GregorianDateTimeFormat.MonthNames = new string[] { "J1", "F2", "M3", "A4", "M5", "J6", "J7", "A8", "S9", "O10", "N11", "D12", "" };
buidler.GregorianDateTimeFormat.MonthGenitiveNames = new string[] { "J1", "F2", "M3", "A4", "M5", "J6", "J7", "A8", "S9", "O10", "N11", "D12", "" };
buidler.Register();

calendar.Calendar.DayNameFormat = DayNameFormat.Full;
this.radDateTimePicker1.Culture = new CultureInfo("my-MY");

I hope this will be useful. Should you have further questions, I would be glad to help.

It's a good way, thanks . but I changed the DateTimePicker Font(use my own font), and the week font not change....only the datetimepicker textbox font is changed.

Hi Qakmak,

Thank you for writing back.

To change the font of the week cells in the calendar you will have to access them individually. Continuing from the code in my previous post you can add the following to achieve your goal:

foreach (CalendarCellElement cell in ((MonthViewElement)calendar.Calendar.CalendarElement.Children[0].Children[2]).TableElement.Children)
{
    if (!int.TryParse(cell.Text, out outint))
    {
        cell.Font = new Font(this.radDateTimePicker1.Font.FontFamily, 12);
    }
}

I hope this will help. Do not hesitate to write back with further questions.

Hello Qakmak,

Thank you for writing back.

Please find attached a screenshot which illustrates what you have to do to apply a font to the cells you want. You have to apply the font repository to the CalendarCellElement.Header state (green indicators). If you do not have this state you can add it (blue indicators on the image). 

I hope this helps. Feel free to write back with any further questions.

and when I'm changed the Calendar font and font size, that's like this:(look the picture)

Hello Qakmak,

Thank you for writing back.

You can use the HeaderHeight property to increase the height of the header row of RadCalendar. This will give your font more space to draw.

I hope this will be useful. Feel free to write back.

Sorry, I can't find it.

Hello Qakmak,

Thank you for writing back.

The property is accessible directly from RadControl you should be able to locate it inside the property grid of the Visual Studio designer. I have attached a screenshot of the property set in my machine.

I hope this will be helpful. Should you need further assistance, I would be glad to provide it.
