Form-Field Validation: The Errors-Only Approach By Christian Holst June 27th, 2012 FormsInteraction DesignUsability 49 Comments Error pages for form-field validation are dreadful. You’ve just filled out 20 form fields, yet you get the same bloated page thrown back form error messages design in your face because a single field failed to validate. I clearly recall the often loud sighs of despair during our last usability study each time a test subject encountered a validation error page. We also noticed that test subjects who had been exposed to validation errors began to take preventive actions to avoid them in subsequent steps, by writing things such as “N/A” in the “Company name” field if in doubt about whether the field was optional. 1 When getting the exact same page but with an error message, the user will feel they have made little or no progress, despite having typed 90% of the form fields correctly. (Image: Blue Nile2) Some of the frustration with validation error pages likely stems from the user being returned to the same page they came from. Being returned to the exact same page is problematic for a couple of reasons: With all form fields still displayed (valid or not), the user might have difficulty identifying the

Article Continues Below 41 comments Share this on You can blame most forms’ poor etiquette on the way they’re built. Web forms that use a basic submit-and-refresh model of interactivity don’t respond until http://stackoverflow.com/questions/1940595/displaying-error-messages-in-c-sharp-web-forms you hit the “submit” button—but it doesn’t have to be this way. Real-time inline validation can help people complete web forms more quickly and with less effort, fewer errors, and (surprise!) more satisfaction. Inline validation gives error messages people several types of real-time feedback: It can confirm an appropriate answer, suggest valid answers, and provide regular updates to help people stay within necessary limits. These bits of feedback can be presented before, during and / or after users provide answers. Putting inline validation to the test To better understand the design considerations behind inline validation, I worked with Etre, a London-based usability firm, to test 22 average users on six variations form error messages of a typical web registration form. Aramys Miranda developed the form we used with our users, who ranged in age from 21 to 49. Fig. 1. The basic registration form we tested had no distractions so people could focus on the task of “creating an account.” Of our six forms, the control version validated input only when someone clicked its “create account” button. The other five versions used different methods of inline validation. We measured success rates, error rates, completion times, satisfaction ratings, and standard eye-tracking metrics for each variation. We presented each form randomly to minimize familiarity bias. What did we learn about inline validation? Our participants were faster, more successful, less error-prone, and more satisfied when they used the forms with inline validation. Eye-tracking also showed that they “fixated” on the forms with inline validation less frequently and for less time, which shows that they found these forms easier to process visually than the forms without inline validation. This was likely because they didn’t have to reread the entire form after submitting it to resolve any errors—instead, they resolved errors as they went along. As you can see in the video below, people got a response from the control version of the form only after they completed it to their satisfaction, and clicked the “

How do i go about displaying the errors?i know of item validations but cant apply that using if and else. however if i use try catch, i dont know which code displays the error message to user. but i know for sure i cant use SC.writelines. a sample of my code is below.please advice.. protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) { string strConn; string userType; strConn = "Provider=MIcrosoft.Jet.OLEDB.4.0;data Source=" + Server.MapPath("App_Data/test.mdb"); OleDbConnection mDB = new OleDbConnection(strConn); mDB.Open(); userClass aUser = new userClass(); if (aUser.verifyUser(mDB, Login1.UserName, Login1.Password)) { userType = aUser.getUserDesc(); if (userType.ToLower() == "customer") { Response.Redirect("StaffMenu.aspx"); } else if (userType.ToLower() == "front desk") { Response.Redirect("StaffMenu.aspx"); } else if (userType.ToLower() == "technician") { Response.Redirect("StaffMenu.aspx"); } else if (userType.ToLower() == "admin") { Response.Redirect("StaffMenu.aspx"); } } else { e.Authenticated = false; } mDB.Close(); when the program moves to the User class to run the verify method, it does so by running the following bock of code.. public bool verifyUser(OleDbConnection mDB, string userIDStr, string userPwrdStr) { string sqlQuery; OleDbCommand cm
