dear friends,

I have two textboxes with calendar extenders with it on my page.

First Textbox is Issued Date and second textbox is Expiry Date.

if i select the Issue date from calendar as 11/05/2013 for Expiry date i should not select the previous date.

Only further dates must be selected for expiry date.

Expiry date will be based on Issued Date.

can you please help me.

thanks in @dvance

So, try out.
2 options:
1. On selection of a date, compare with issued date and raise a message if it is before issued date.
2. disable the dates before the issued date so that it cannot be selected.
