for example today's date is 20/08/2013 and i try to insert record for date 01/08/2013 then

there must be a validation like " you can't insert record with previous date" ..

Javascript

function verifyDate(sender, args)

        {

            var d = new Date();

            d.setDate(d.getDate() - 1);

            if (sender._selectedDate < d)

            {

                alert("Date should be Today or Greater than Today");

                sender._textbox.set_Value('')

            }

        }

<asp:TextBox runat="server" ID="txtDateFrom" Text=" "                            >asp:TextBox>

<cc1:CalendarExtender ID="CalendarExtender2" runat="server" TargetControlID="txtFromDate"

                                                                    Format="dd/MM/yyyy" OnClientDateSelectionChanged="verifyDate">

here it is in code behind

DateTime date1=new DateTime(2013,7,29);
var t = DateTime.Compare(date1,DateTime.Now);
if(t==-1)
{
Response.Write("you can't insert record with previous date");
}

in javascript

function CompareCurrentDate(sender, args) {
var userDate= "07/20/2013";
var currentDate= "08/02/2013";
var d1 = Date.parse(fromDate);
var d2 = Date.parse(toDate);
if (d1 < d2) {
alert("Date can't be before todays date");
}

}

Hi,
Are you looking for in ASP.NET or Windows Form?

in windows form if you are using DateTimePicker control, then you can restrict the user by setting the property.

Other wise try like this

DateTime date1=new DateTime(2013,7,29);
var t = DateTime.Compare(date1,DateTime.Now);
if(t==-1)
{
Response.Write("you can't insert record with previous date");
}
