arrayIndexOf Using ArrayIndexOf , find the matched items from array collection. If array items are matched then returns true otherwise returns false. For Example filter an observable array collection using indexOf() .   var filterAnArrayByArrayIndexOf = function (Text) {            try {                var filterText = Text.toLowerCase();                         if (!filterText) {                    return selectionList();                }                else {             ...

arrayPushAll This is basically use for push the old array collection in the  new array collection by using the ko.utils.arrayPush() For example  newArrayListItems () is a new array list and  oldArrayItems () array list. ko.utils.arrayPushAll(newArrayListItems(), oldArrayItems);

arrayFirst Array firstly returns only first items which are matched. For Example    var findSelectedCodeSetFromLabel = function (label, codeSet) {           try {                   if (codeSet != null && codeSet.length > 0) {                      return ko.utils.arrayFirst(codeSet, function (item) {                           return (item.Label.toLowerCase().indexOf(label.toLowerCase()) > -1);                      });                 ...

arrayFilter Array filter is availing an observable-array and returns true if array of items are match otherwise returns false.  For example filter an observable array using computed binding  as given below. var filterSelections = ko.computed(function (Text) { try { var filterText = Text.toLowerCase(); if (!filterText) { return selectionList(); } else { if (selectionList().length > 0) { return ko.utils.arrayFilter(selectionList(), function (item) { if (item.SelectionLabel.toLowerCase().indexOf(filterText) > -1 || item.SelectionDescription.toLowerCase().indexOf(filterText) > -1) { return true; } else { return false; } }); ...

Delegate in C# Delegate is an object which holds the references to a method within delegate object. Delegate is a type-safe object. Delegate is invoke to methods in asynchronously manner. Delegate encapsulates a static methods or instance methods instance. Delegate can be with parameters or without parameters. Most importent use of delegate: 1. Improve the performance of application. 2. Encapsulat to methods call from caller. 3. Call a method asynchronously. Three steps for using delegates: 1. Declare 2. Create 3. Point Delegate are Two types: 1. Delegate 2. Multicast Delegate Generic readymade delegate are : 1. Func < input, output > 2. Action < inputParameter > 3. Predicate < inputParameter > Delegate is use when we needed to pass the single reference to a method within delegate object. Multicast Delegate is use when we needed to pass the nore then one reference to a method within delegate object. ...

1.        KnockoutJs is a MVVM pattern. 2.        MVC is a design pattern. 3.        Knockoutjs work like connected mode. 4.        MVC work like disconnected mode. 5.        Knockoutjs supported two types of binding a.        One-way binding b.        Two-way binding 6.        MVC supported only one-way binding. 7.        In Knockoutjs, UI part automatically update when your data model update. 8.        In MVC, not update UI automatically when your data model update. Need event to call data model and update it. 9.        In MVC, model part directly binds with the view page. 10.    In KnockoutJs, model part is not directly bind ...
