Validation Contol in Mobile Form

Introduction

In this article  i'll be showing the power of Validation Control which you can use with Mobile Application. There are total six Valiation Control as provided. Here i am showing four of them in  this example and the rest two are Valiationsummary and  CustomValidator.

CustomValidator allows you to create a custom client-side or server-side function(in any supported Language)that performs the validation and returns either True or False.

ValiationSummary control Collects the values from the errorMessages property of each control where the validation fails and can present the messages to the user within the page.

So here is the Piece of coe which shows all the validation Control in an Mobile Form, check this out.
