how can i find number of days in a given year and month

Ooh - not quite. If it's a century, it has to be divisible by 400 to be a leap year, so 2000 is a leap year and 2100 isn't.

use modulus (provides the remainder after a division) not divide...
if(year % 4 == 0)
//is leap year
else
//not leap yearLife goes very fast. Tomorrow, today is already yesterday.
Many Thanks and i'm very happy from Your cooperation

is 2100 really not a leap year? EDIT: It's OK I WIKI it and got an answer ;)

Ok this is what you should use instead...
if(year % 4 == 0 && year % 100 == 0 ? year % 400 == 0 : true)//hope you get that logic
//is leap year
else
//not leap yearLife goes very fast. Tomorrow, today is already yesterday.
you realy have come to the right solution thank you

Or if you don't want to reinvent the wheel:
if (DateTime.IsLeapYear(year)) {
// is leap year
} else {
// not leap year
};)
Despite everything, the person most likely to be fooling you next is yourself.

Have a look at this:
private void button1_Click(object sender, EventArgs e) {
button1.Enabled = false;
int year = dateTimePicker1.Value.Year;
int month = dateTimePicker1.Value.Month;
DateTime start = new DateTime(year, month, 1);
dateTimePicker1.Value = start;
int days = DateTime.DaysInMonth(year, month);
for (int i = 0; i < days; i++) {
dataGridView1.Rows.Add();
dataGridView1.Rows[i].Cells[0].Value = start.AddDays(i).DayOfWeek;
dataGridView1.Rows[i].Cells[1].Value = start.AddDays(i).ToShortDateString();
}
}Despite everything, the person most likely to be fooling you next is yourself.
