Hello I have a .aspx(c#) webform where a user enters his firstname, age, city, email, phone number
and in the end hits a submit button. currently i am doing validation just to know if he has entered anything or not.
I want to do something like this. when the user hits submit button we capture his values and check all values for eg: phone number shouldnt be character, email should be proper etc and if one of the validation fails we still continue and in the end we let the user know which all controls or fields have failed showing him some message on the web page like enter correct phone number, enter correct email.
I hope i made the scenario clear. how should i approach this?
