Restricting User While Entering In Textbox?

Apr 16, 2009

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

Now what I want to do is:

1. When user enters in textbox then while typing; first letter should be automatically come up as capital letter & next as small case letters. E.g. If I am typing my first name then while typing it should be Sanjay & not as sanjay or sAnjay.

2. While typing in textbox user should not be allowed to enter white space in between the words like Sa jay this should not be happen. If user types like this I want to give an alert that something like please do not use space in between name.

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

Sep 9, 2009

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, 2010

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.
