Question about Registration Information Validation

Hello, first off want to take the time to thank anyone that reads this. I'm new to .NET/Java Script/AJAX so I'm sort of at a crossroads here for the most logical way to approach what I am trying to do.

I have a registration page with these required fields. E-mail, Confirm e-mail, Date of Birth, Gender, Country, Alias, Password, and Confirm Password.

What I am looking to do is make sure the e-mail is valid (has @xxx.yyy), compare the confirm e-mail and e-mail to make sure they match. I just want to make sure that Date of Birth, Gender and Country have information in them. Lastly I want to compare the user name to a table of 'banned words', and then lastly just make sure the two password fields match.

I'm just really stuck as to the most logical and efficient way of doing this. I've been searching for things on google but nothing has come up that made he light bulb go off in my head.

Any help is appreciated, and once again thanks for taking your time to look at this.

just use asp.net validatores

 

for all but the banned words use the appropriate .net validators as JZ says.

For banned words you will need to use a custom validator and write a serverside check on if the textbox contains your unwanted words. A basic example would be:

Protected Sub CV1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
        If textbox1.Text.Contains("poo") Then
            args.IsValid = False
        Else
            args.IsValid = True
        End If
End Sub

Code (VB.Net):

 

Check out the validation toolkit. It can handle most data format validation.

 

Appreciate all the replies. I looked into it and got it done.

Thanks to everyone who posted.
