And validating user input is the bane of every software developer existence.

But these patterns used in Reg Exp can be very simple.

Here Mudassar Ahmed Khan has explained the following three types of character length or count validations for ASP. Here Mudassar Ahmed Khan has explained with an example and attached sample code, how to filter Grid View records using Text Box in ASP. To accomplish the task I have made use of Sql Data Source with Filter Expression along with Filter Parameters to filter records and bind the ASP. The Text Box will be specified as Control Parameter in the Sql Data Source Filter Parameters, so that when text or value is entered in the Text Box and the Search Button is clicked, it will filter the Grid View Records based on Starts with LIKE Search.

For example:- - Minimum 8 characters at least 1 Alphabet and 1 Number - Minimum 8 characters at least 1 Alphabet, 1 Number and 1 Special Character - Minimum 8 characters at least 1 Uppercase Alphabet, 1 Lowercase Alphabet and 1 Number - Minimum 8 characters at least 1 Uppercase Alphabet, 1 Lowercase Alphabet, 1 Number and 1 Special Character - Minimum 8 and Maximum 10 characters at least 1 Uppercase Alphabet, 1 Lowercase Alphabet, 1 Number and 1 Special Character Here Mudassar Ahmed Khan has explained with an example and attached sample code, how to make use of Sql Data Source Filter Expression with Filter Parameters to filter records in ASP. In order to filter the Grid View records, I am making use of a Drop Down List control that will be used to select the filter records in Grid View. The selected File’s extension will be validated using a Regular Expression and an error message will be displayed when an invalid file is selected. Now you can ask questions directly to me on my new site ASPForums.

var is Email_re = /^\s*[\w\-\+_]+(\.[\w\-\+_]+)*\@[\w\-\+_]+\.[\w\-\+_]+(\.[\w\-\+_]+)*\s*$/; function is Email (s) { return String(s).search (is Email_re) !

Net Regular Expression Validator samples to validate Minimum and Maximum text Length and also different configurations like Alphanumeric with special characters, Alphanumeric, Alpha and Numeric configurations.

In a previous post trim a string from white space by Java Script function ( or Another Java Script function for trim a string from white space ) and Java Script function-Splits the string by given separator and returns an array with trimmed items, Some Regular expressions have been used.

Patterns are defined using string literal characters and metacharacters.The following is some useful regular expression based javascript function, some works like validating user input will be very simple by using them. )|(\.\d+))\s*$/; function is Decimal (s) { return String(s).search (is Decimal_re) !No.1: Check if string is non-blank // Checks that an input string is a decimal number, with an optional +/- sign character. = -1 } // checks that an input string looks like a valid email address.Fortunately, Java Script 1.2+ has incorporated regular expressions.Java Script has an alternate syntax for creating Regular Expression objects that implicitly calls the Reg Exp constructor function.
