use order by datecolumn-- to get records in datewise

I think that in ClosUp event from "fromDate" you could configure something like:

dateTimePicker2.MinDate = dateTimePicker1.Value

This way, user can only choose a data equal or after the first date.

C#

DateTime selectedDate = Convert.ToDateTime(dtpExpireDate.Value);
DateTime todayDate = Convert.ToDateTime(DateTime.Now);
if (selectedDate < todayDate)
{
    MessageBox.Show("Selected date Must be greater then Today's date");
}

Instead of dateTimePicker2_ValueChanged
Use dateTimePicker2_CloseUpevent , so your final code will be

private void dateTimePicker2_CloseUp(object sender, EventArgs e)
{
    DateTime fromdate = Convert.ToDateTime(dateTimePicker1.Text);
    DateTime todate1 = Convert.ToDateTime(dateTimePicker2.Text);
    if (fromdate <= todate1)
    {
        TimeSpan daycount = todate1.Subtract(fromdate);
        int dacount1 = Convert.ToInt32(daycount.Days) + 1;
        MessageBox.Show(Convert.ToString(dacount1));
    }
    else
    {
        MessageBox.Show("From Date Must be Less Than To Date");
    }
}

CloseUp event is triggered only when the user finally selects a value. ValueChanged event will fire when you change the month also that was your issue.

I have corrected your variable names in code :) to run in my local box

mark it as solution if this resolved your issue
