Joe,

I am trying to add validations upon Registration that when a user input same value on UserName and Password it will alert "Same Username and Password is not Allowed". I use OnTextChanged event and set autopostback="True".

Since Register.aspx does not include the code behind I place my code on the aspx page.

<script type="text/C#" runat="server">

</script>

I placed my code inside this script. There is a Textbox control for username and password. The problem is it returns an error "The name 'UserName' does not exist in the current context".

Your help is greatly appreciated.

Thanks.

Thanks Joe. 

I set password with minimum nonalphanumeric character 

then username to alphanumeric.

Thank you.
