View 4 RepliesI have to make a login form using vb.net. The login form should either accept
Username ID or
Email ID or
Phone number
---- either of one ,and match it with the password of the corresponding record in the user table.
The user table has following column:- U_ID(varchar),mail(varchar),Phone(Number),Password(Varchar)
The form has two textfields - 1. Username
2.Password
And a submit button. If combination is correct I should be redirected to the Index page.
But I don't have to scan through all the columns of the user table to match the password.
(a)If the user enters user_id say- ID 10012 then we should be able to search only the record in the user_id column as it has alphanumeric or varchar data type and match with corresponding password.
(b)If the user enters Email id we should be able to search through the email id column as email id contains "@ and ." sign.
(c)If the user enters phone number then we should search only the phone column as it has numeric datatype.
I have been attempting to find a solution for my phone number formatting problem for 2 hours now and I am not getting any closer. My 10 digit phone number is stored as a varchar(14) without any formatting (just 10 digits).

View 1 Repliesi have two textboxes and two required filedvalidators for each one.and i have to validate based on the radio button slections.
1)if i select Radiobutton1 it has to validate both textboxes.
2)if i select Radiobutton2 it has to validate only one textbox.
I have been trying to figure out how to use <asp:requiredfieldvalidator> with ValidationExpression but am having a difficult time understanding the syntax of ValidationExpression. I'd like to make sure one textbox's number (1-12) is equal to or higher than the other textbox's (1-12) number. How is this accomplished and what's the syntax of ValidationExpression (hopefully I'm stating the question correctly).

I have a peculiar situation at hand in which I need to validate a pair of dates in an ASP.Net web app.This is how my page looks like : I have a "From Date" field which consists a set of three dropdownlists ( for Year , Month and Date) I have a "To Date" field which also consists a set of three dropdownlists ( for Year , Month and Date). There is a "Download Report" button on the screen ( which allows a user to download a report for the specified date range) All these six dropdownlists are wrapped in a user control. Now all the 6 dropdownlists have a default "please select" value. When a user lands on the page for the first time , all dropdownlists are set to "please select". The "Download" button is enabled only after valid 'From' and 'To' dates are selected. Now my requirement is that :
When a user lands on the page for the first time , no attempt to validate the dates should be made until he selects all the 6 dropdownlists at least once. When the 6th dropdownlist is selected , the From and To dates should be validated. Once a user has selected all 6 dropdowns once , subsequently on every dropdownlist postback , the dates should be validated. My Issue: What's the best way to track these 6 distinct postbacks ( for each of the dropdowns) before starting to validate the From and To Dates.
