Dear murkalkiran... this code working well and good. But I need if I am select from datePicker the value shold change. for example: the datepicker date is: 19-11-2014. if select any date from current month like 11th month, the textbox date value must be 31-10-2014. Moreover if i am select any date from 10th month, the text box value must be 30-09-2014 like only.

C#

private void YourDateTimePicker_ValueChanged(object sender, EventArgs e)
{
    DateTime val = YourDateTimePicker.Value;

    int pYear = val.Year;
    int pMonth = val.Month - 1;

    if (pMonth == 0)
    {
        pMonth = 12;
        pYear--;         
    }

    DateTime lastDayPrevMonth = new DateTime(pYear, pMonth, DateTime.DaysInMonth(pYear, pMonth));

    YourTextBox.Text = lastDayPrevMonth.ToString("dd-MM-yyyy");
}
