are you using jquery unobtrusive validation? Or do you need a custom javascript validation? server side validation?

You can use CompareValidator for that. Follow the steps:

1. Drag and drop a CompareValidator from the toolbox to a suitable place you like.
2. Set the Operator to GreaterThan
3. Set the ControlToValidate property to the TextBox (which has the year)
4. Set the ValueToCompare on the Page Load Event to the current year

Do tell me if that helps. If not, please comment and I will modify the answer accordingly. Thanks.

Mohamed Mitwalli 16-Jul-12 4:08am

you have to write nothing it's Client side validator

Pankaj Nikam 16-Jul-12 4:10am

In the page load, you have to write something like:

CompareValidator1.ValueToCompare = DateTime.Now.Year;

Hi,

If your requirement is like that depending on System Date you only accept Next Year of current System Year.

In time of validation you will check Text Box value is Equals to

C#

System.DateTime.Today.Year+1

or not if not then throw some validation error

:)

If you try it on web then OnLoad put current Year value at hidden field On in Session On Cookie and Then On Submit check using Javascript by writing some javascript.

Do you need that java script

If you follow my answer you will get both validations, Server side (code) and Client Side (JavaScript) too.

Software Engineer 892 16-Jul-12 4:18am

May be , due to this it is not showing the year problem.

Suvabrata Roy 16-Jul-12 4:46am

As I told add this
Add a Hidden filed
<input type="Hidden" id="hdCurrentYear" runat="server" value=""/>

then Set Its value at Page Load from Server

hdCurrentYear.value=System.DateTime.Today.Year;

Then Add This javascript function

On Submit Of From

function Validation()
{
var curYear = document.getElementById('<%= hdCurrentYear.ClientID %>').value;
var curValue = document.getElementById('<%= myTextbox.ClientID %>').value;

if(parseInt(curValue) <= parseInt(curYear))
{
alert("Please enter a valid year"); // Or any other stuff...
return false;
}
// Other validations...

return true;
}
