Restricting User While Entering In Textbox?

Apr 16, 2009 12:14 PM

I am working on registration page. I am accepting some general inputs from user. Like First Name, Middle Name, Last Name etc.

Web Forms :: Entering A Hexadecimal Value In A Textbox?

Sep 09, 2009 03:17 PM

Our customer needs to add a value like 'NAK' to the database. This is a hexadecimal value (think it's either 15 or 21). How can the user enter this in the textfield? Or, what do I have to do to allow this to be entered?

If he enters '21', it just saves '21' to the database because he once asked for backslashes in this particular field.

Then, once I know how to enter the hexa value, can I expect any trouble in saving this to the database?

Is It Possible For A User To Recover Their Password By Entering Their E-mail Address Alone

Jan 19 10

Is it possible for a user to recover their password by entering their e-mail address alone?

Right now I am using the PasswordRecovery control, and i have security questions disabled. So all the user has to do is put their User Name, and hit submit, then their password is e-mailed to them.

But, a lot of my users forget their User Name, so right below I have a User Name recover section. The user inputs their e-mail address, and their corresponding user name shows up.

I would like to simplify this and just require the user's e-mail address to provide them their user name AND password.
