Add remove select and set items in select drop down list

By

Introduction:
In my previous article I have explained aboutConvert string to lowercase-uppercase in xslt. In this article I am going to explain about how to add,remove,check and set the items in select using jQuery

Explanation:
For example in my form I have a select option with id “seloption”. To add a item with value “option1” and with text “Option-1” below code is used.


var options = jQuery('#seloption').attr('options');          
options[options.length] = new Option('Option Name', 'option value', true, true);

Now to remove the option with value “option1” below code is used.

jQuery("#seloption option[value=option1]").remove();

To check whether the option with value “option1” is present in the select below code is used

jQuery("#seloption option[value='option1']").length>0

If the option is present then it will return the index value of the option. Otherwise it will return -1. To make the option “option1” as a selected option below code is used.

jQuery("#seloption ").val("option1");

To get the selected value of the select below code is used.

var value = $('select#dropDownIdoption:selected').val();

C# Extension Methods Example

By
In this article i am going to explain about Extension Methods  with example. Extension methods enable you to "add" methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type. Extension methods are a special kind of static method, but they are called as if they were instance methods on the extended type. For client code written in C# and Visual Basic, there is no apparent difference between calling an extension method and the methods that are actually defined in a type. If you do implement extension methods for a given type, remember the following points: An extension method will never be called if it has the same signature as a method defined in the type. Extension methods are brought into scope at the namespace level. For example, if you have multiple static classes that contain extension methods in a single namespace named Extensions, they will all be brought into scope by the using Extensions; directive. ...
