Before Ajax Control Toolkit 4.0 or Any other
Calender such as Asp.net Calender Control it is very Lengthy and Long Process to
disable the past or future dates from Calendar. because to perform this type of
task we need to write more than a hundred lines of code in JavaScript or any
other scripting Language.
But now by using the Ajax control Toolkit 4.0 you can perform the same task in
just one line of code..!
Applicable
- It is useful when their is requirement of
only allow Present date or allow only limited future date from
present date of calender.
- It is useful in a application such as
Travel Booking Application or Daily Transaction Application or
according to your requirement as you wish.
Note
- You need an Ajax Control Toolkit 4.0
and above,its only works in this version
- Don't forget to add the Ajax control
toolkit assembly reference at the top of the .aspx page source code
- Don't forget to use either Script
Manager or ToolScript Manager in a .aspx page because whenever
you use any Ajax control you need to use one of them to handle Script .
