namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            DateTime fromdate = DateTime.Parse(Convert.ToDateTime(dateTimePicker1.Text).ToShortDateString());
            DateTime todate = DateTime.Parse(Convert.ToDateTime(dateTimePicker2.Text).ToShortDateString());
            if (fromdate > todate)
            {
                MessageBox.Show("from date is greater than to date");
            }    
        }

        {
            if (dateTimePicker1.Value.Date > dateTimePicker2.Value.Date)
