Defining a preselection

[Bastian Krones]

Hello,

i want to list some tasks in which each task a new dropdown appears with customers.
i solved it to get 2 models receiving 2 JSON requests.

Knockout:

function Task(data) {

            this.ID = ko.observable(data.ID);

            this.Description = ko.observable(data.Description);

            this.ClientName = ko.observable(data.ClientName);

            this.ClientFK = ko.observable(data.ClientFK);

            this.CustomerName = ko.observable(data.CustomerName);

            this.CustomerFK = ko.observable(data.CustomerFK);

        }

        function Customer(data) {

            this.CompanyName = ko.observable(data.CompanyName);

            this.CustomerID = ko.observable(data.CustomerID);

            this.AnzahlTasks = ko.observable(data.AnzahlTasks);

        }

        function TaskListViewModel() {

            // Data

            var self = this;

            self.tasks = ko.observableArray([]);

            self.customers = ko.observableArray([]);

            $.getJSON("/api/CustomerList", function (allData) {

                var mappedCustomer = $.map(allData, function (item) { return new Customer(item) });

                self.customers(mappedCustomer);

            });

            // Load initial state from server, convert it to Task instances, then populate self.tasks

            $.getJSON("/api/Task", function (allData) {

                var mappedTasks = $.map(allData, function (item) { return new Task(item) });

                self.tasks(mappedTasks);

            });           

        }

        ko.applyBindings(new TaskListViewModel());

View:

    <li>

        <select data-bind="options: $root.customers, optionsText: 'CompanyName', optionsCaption: 'Choose...'"></select>

        <input data-bind="value: CustomerName" /><br />

        <input data-bind="value: ClientFK" /><br />

    </li>

So far so good. I am just not able to get a preselect. Every task should have it's onw preselected customer of the list "customerlist".

How do i solve that?

You're not assigning a value to the select list, I'm assuming this is part of a foreach display.
