Hi Abhimanyu,
Why should this be Ajax based? There is no need to send data to the
server in this instance as it's readily available to the client when
they enter a start date.
With jQuery (my js framework of choice) adding 7 days could be as
simple as:
$( "#ModelNameStartDate" ).change(function () {
var enteredString = this.val();
var stringParts= enteredString.split("/");
var jsDate = new Date(stringParts[2], stringParts[1],
stringParts[0]);
var endDate = jsDate.setDate(jsDate.getDate()+7); // add 7 days
$( "#ModelNameEndDate" ).val( endDate );
});
To add months or years you would use:
var endDate = jsDate.setMonth(jsDate.getMonth()+3); // add 1 months
var endDate = jsDate.setFullYear(jsDate.getFullYear()+1); // add 1
year
Of course the above relies on the user adding a valid start date with
the correct seperators so would need a fair bit of extra work to
ensure that was the case.
I personally use jQuery and jQuery UI to add theme-able datepickers to
my date fields, which significally improves the user interface (forces
valid dates and a specific format). If you want to know how to do
this get back in touch.
