Help Desk Call Date and txt Help Desk Request Date in the code-behind but really dont know how to fix it. Help Desk Call Date - txt Help Desk Request Date : "30-8-2008 " I am new to programming, but looking at this I feel IBO.
Help Desk Call Date is expecting the format which is not provided by txt Help Desk Request Date... The problem you are talking about is related with a specific scenario.
May I request you to post it in the Questions section of this website? A little hint in order to solve your problem is "30-8-2008 " is not a correct Date Time format (try to convert or parse it to Date Time and you will get error). tulsi When you will use Sql Data Source, you are writing your select query, connectionstring and other stuffs at the page itself.
3-Tier architecture is a very well know buzz word in the world of software development whether it web based or desktop based. Below is the code for BAL (Your can overwrite your default written code for the class file by pasting this code). You can also navigate to another page your created (list.aspx) and try updating, deleting records.
