Hi Arjun Validation is of two types: 1. Client Side 2. Serve Side Client side validation is good but we have to be dependent on browser and scripting language support. Client side validation is considered convenient for users as they get instant feedback. The main advantage is that it prevents a page from being postback to the server until the client validation is executed successfully. For developer point of view serve side is preferable because it will not fail it is not dependent on browser and scripting language. You can use ASP.NET validation which will ensure client and server validation. It work on both end; first it will work on client validation and than on server validation. At any cost server validation will work always whether client validation is executed or not. So you have a safety of validation check. For client script .NET used JavaScript. WebUIValidation.js file is used for client validation by .NET Validation Controls in ASP.NET An important aspect of creating ASP.NET Web pages for user input is to be able to check that the information users enter is valid. ASP.NET provides a set of validation controls that provide an easy-to-use but powerful way to check for errors and if necessary display messages to the user. There are six types of validation controls in ASP.NET 1.RequiredFieldValidation Control 2.CompareValidator Control 3.RangeValidator Control 4.RegularExpressionValidator Control 5.CustomValidator Control 6.ValidationSummary For their proper use read this tip and tricks http://www.dotnetcurry.com/ShowArticle.aspx?ID=121

Hi Arjun There are 6 validation controls in asp.net.They are 1. RequiredFieldValidator :-Makes an input control a required field 2. CompareValidator :-Compares the value of one input control to the value of another input control or to a fixed value 3. RangeValidator :-Checks that the user enters a value that falls between two values 4. RegularExpressionValidator :-Ensures that the value of an input control matches a specified pattern 5. CustomValidator :-Allows you to write a method to handle the validation of the value entered 6.
