Here is what I'm trying to achieve: The user enters in the textbox a date. It can be:
20.04.2010 or 20/04/2010 or
01Apr2010 or Apr 01 2010...
Any other formats should be forbidden. When the user leaves the textbox then the date should be displayed as 01-Apr-2009. I already tried but I got only when am entering the numbers only like (21-04-2010) but I want to entering the string like apr, jan, nov .

I have a simple web form that takes data inputted by a user online but I can't get the date field formatted so it can allow UK short date format to be entered. I need to allow dates to be entered like this: dd/mm/yyyy but currently if I enter the UK format date 25/02/2011 I get an error, as the field is in US format (mm/dd/yyyy).
It's a SQL database created from within MS Visual Web Developer 2010, and I'm a SQL newbie.

I have an ASP.Net UpdatePanel that updates on a timer. Within the UpdatePanel and nested in a GridView, I have a TextBox that the user enters a value in with a submit button. Everything works fine, except if the user does not submit the value before the timed interval, the text is removed from the TextBox. Is there a way to persist the user entry into the TextBox between updates? Is there a better way of doing this?

How do I get this textbox to do a postback once the user has entered data?
I have created a class file which gets me the state codes,license numbers and the expiration dates for the same.
I fetch the expiration dates in string format.
Each customer can have many licenses.
I have changed the format of the date (initially appearing as YYYY/MM/DD 00:00:00 when retrieved from database) to MM/DD/YYYY.
After retrieving all the licenses pertaining to a single customer, I bind them to a datalist.
Now the requirement is that for each customer, I need to sort the licenses according to the latest expiration date and then display the same.
How can this be achieved ?

View 4 RepliesI have the following date in string format "2011-29-01 12:00 am" . Now I am trying to convert that to datetime format with the following code:
DateTime.TryParse(dateTime, out dt);
But I am alwayws getting dt as {1/1/0001 12:00:00 AM} , Can you tell me why ? and how can I convert that string to date.
EDIT:
I just saw everybody mentioned to use format argument. I will mention now that I can't use the format parameter as I have some setting to select the custom dateformat what user wants, and based on that user is able to get the date in textbox in that format automatically via jQuery datepicker.
