C#

private void dateTimePicker1_ValueChanged(...)
{
dateTimePicker2.Value = DateTimePicker1.Value.AddDays(1);
}

private void dateTimePicker2_ValueChanged(...)
{
       if(dateTimePicker2.Value < DateTimePicker1.Value)
       {
         MessageBox.Show("Cannot be less than previous date");
         dateTimePicker2.Value = DateTimePicker1.Value.AddDays(1);
       }
}

That wouldn't prevent User from selecting an earlier date on dateTimePicker2 afterwards.

Use Compare validater

XML

<asp:CompareValidator ID="CompareValidator1" runat="server"  ControlToValidate="txtenddate"
ErrorMessage="End Date is not less than Start Date" Operator="GreaterThanEqual" Type="Date" Text="*" ControlToCompare="txtstartdate"></asp:CompareValidator>
