Hi I have 3 textboxs :-
1) StartDate
2) EndDate
3) MyDate
all the 3 of them has Date Values picked up from a Calender.

I want to validate them so that MyDate should be between the Start Date and End Date using Javascript.
If invalid, then I want to display a message.
How to do that?
I think we should be using custom validation controls to do that but how to implement that??
Any pointers will be helpful.

I want to validate them so that MyDate should be between the Start Date and End Date using Javascript.
There can be various ways to do it. Simplest is to raise a JS method on any event like onclick or page submit, where you find the three controls, get the three dates and compare.

Sample:

JavaScript

function checkDateValues(startDateValue, endDateValue, myDateValue)
{
  var sDate = new Date(startDateValue);
  var eDate = new Date(endDateValue);
  var mDate = new Date(myDateValue);
  if(mDate > sDate && mDate < eDate)
  {
     // All good
     return true;
  }
  return false;
}
