Microsoft.Live.Services.ContactCategoryCollection = function();


A ContactCategoryCollection is a collection of ContactCategory items that describe the categories to which a contact belongs. Each ContactCategory item provides properties and methods for working with the Windows Live category resource.

The following example demonstrates how to get a DataContext instance from the App class dataContext property, and create a ContactCategoryCollection instance, and list the properties of each ContactCategory item in the collection.

var sb, out, br = "</br>";
function appLoaded(applicationLoadCompletedEventArgs) {
    var dataContext = wl.App.get_dataContext();
    out = document.getElementById("Output");
    sb = "Loading ContactCategories." + br;
    dataContext.waitForsignIn(function(signInCompletedEventArgs) {
        if (signInCompletedEventArgs.get_resultCode() !== wl.AsyncResultCode.success) {
            alert("Sign in failed.");
        else {
            dataContext.loadAll(Microsoft.Live.DataType.contactCategories, contactCategoriesLoaded);
function contactCategoriesLoaded(dataLoadCompletedEventArgs) {
    if (dataLoadCompletedEventArgs.get_resultCode() !== Microsoft.Live.AsyncResultCode.success) {
        alert("ContactCategories failed to load");
    contactCategoriesCollection = dataLoadCompletedEventArgs.get_data();
    for (var i = 0; i < contactCategoriesCollection.get_length(); i++) {
        var contactCategory = contactCategoriesCollection.get_item(i);
        sb += contactCategory.get_title() + ", " + contactCategory.get_id() + br;
    out.innerHTML += sb;
