Is getDueDate() already defined in your js file?

@Suvendu Shekar, it is not working , asking for type expected error at GetType().

First off you need to appreciate that you're not calling javascript from your server code, all registerclientscriptblock does is add javascript to the page you are rendering. In order for your js to work you need a javascript function called getDueDate defined on the page and it has to be defined somewhere at the top so that it is included before your script block. View the source to see where your script is being added and where your getDueDate function is defined and amend as needed.

If getDueDate is a server function this isn't going to work, you can only call javascript, and also remember that you are hard-coded the function to pass whatever is in txtDueDate.Text at the time the page is rendered.
