Solution 1

Do date comparison instead of string comparison.

Try something like:

C#

if (Convert.ToDate(dtdates.Rows[0]["dob"]) < Convert.ToDate("30/11/2007"))  //if dob is before 30/11/2007 than disabling 
{
                        Txt1.Enabled = false;
                        Txt2 = false;
                        Txt2 = false;
 
}

how it achieve in javascript ?

In Javascript: There is 'Date' object instead of DateTime.

Date someDate = new Date("1/1/2011");

Use similar logic based on the event and values you have. Do the date comparison.

Date someDate = new Date("1/1/2011");
.......; missing

Can you Google on it now? I did not gave exact JS code - just told you how it is similar in JS. Further, the line I gave will not throw ';' error. It surely is your code. Recheck it.
