Validating the login interface credentials

Hi Rithika

Here you're trying to validate even before users login to Appian if I understood correctly. However, if users enter wrong credential Appian itself will handle this
Why would we need to validate it on the login page? I just wanted to know what is the business here?

Thanks

Hi Rithika,

Actually I have created a registration page and storing the values of the registered users in database .Now I have created a login page also.Now my problem is I have username and password fields in login page when entered values in those fields , the values should get compared with those in registered database table.If entered values are equal to values in database they should login otherwise throw an error.

Thanks Dhananjay I will try this thing and reply you back once it is done

Hey were you able to achieve what you were expecting?

Yes Thank you I was successful in getting that data.

Can you share a sample expression for the login interface

What do you want to achieve?

To get any access to Appian you already have to log in. There is nothing like a "custom login page" in Appian.

I am creating own custom login page interface and trying to validate them

What exactly do you mean with "own custom login page"?

Hi...

For delete record from grid and also from DB I have created this type of interface
