RadDateTimePicker Custom Format

[Mark K.]

Is there any way to make the "AM" and "PM" in the RadDateTimePicker be lower case without changing the computer's DateTime format?

Hi Mark K.,

Thank you for the question.

You can customize the data format through the CustomFormat property. You also have to set the Format property to custom. Please, consider the following code:

this.radDateTimePicker1.Format = DateTimePickerFormat.Custom;

void radDateTimePicker1_ValueChanged(object sender, EventArgs e)
{
    if (this.radDateTimePicker1.Value.Hour > 11)
    {
        this.radDateTimePicker1.CustomFormat = "\"pm\" hh.mm";
    }
    else
    {
        this.radDateTimePicker1.CustomFormat = "\"am\" hh.mm";
    }
}

Do not hesitate to contact me again if you have other questions.

The code you wrote puts the "am" and "pm" in front of the number, which I've never seen before.  Is that a European thing?  I fixed that, but the real problem is that when you edit the time in the box while the application is running there doesn't seem to be any way to edit the "am" and "pm" to change it to the other.

If I click on the arrow key to increment the numbers, it never goes from am to pm.

The whole edit routine of the time picker leaves much to be desired.  Why does it drop off leading zeros and go to single digits when you put your cursor on one of the numbers?

Hello Mark K.,

You should do the following to specify a time format which includes the "AM", "PM" time part:

this.radDateTimePicker1.Format = DateTimePickerFormat.Custom;
            this.radDateTimePicker1.CustomFormat = "hh:mm:tt";

I hope this helps.

I already have that.  You didn't read the first post.  I was asking how to make the "am" and "pm" be lower case.

Hello Mark K.,

You do not have to change the date time format of your computer. You should just change a few settings of RadDateteTimePicker date time format.

You can do the following:

this.radDateTimePicker1.Culture = new CultureInfo("en-US");                  this.radDateTimePicker1.Culture.DateTimeFormat.AMDesignator = "am";
this.radDateTimePicker1.Culture.DateTimeFormat.PMDesignator = "pm";

You can use any string at the place of "AMDesignator" and "PMDesignator". If you have more questions, please contact us again.
