I successfully filled my bobox. But now I'm trying to set default value for bobox. For example let's say third value from source. This is my input and datasource:

<script>
viewModel.dataSourceType = new kendo.data.DataSource({
    transport: {
        read: {
            url: "/api/Type/Get",
            dataType: "json"
        }
    },
    schema: {
        id: "Id",
        data: "Data",
        model: {
            id: "Id",
            fields: {}
        }
    }
});

<input id="type"
 data-role="bobox"
 data-value-primitive="true"
 data-auto-bind="true"
 data-text-field="Name"
 data-value-field="Id"
 data-bind="value: model.Id, source: dataSourceType">

It's probably really easy but I'm strugling with that. Thank you.

I assume you look for the index configuration option.

Likely the problem is in your model definition, i.e. what you are binding to the bobox.

According with your definition your JavaScript should be something like:

var dataSource = new kendo.data.DataSource({
    type: "odata",
    transport: {
        ...
    }
});

var model = new kendo.observable({
    dataSourceType: dataSource,
    model : { Id: 2 }
});
kendo.bind($("#type"), model);

Where 2 is the value that you want as default (initial) value.

Realize that I have had to declare an extra model for Id since you say in your data-bind definition that value is model.Id.

Maybe you wanted to say:

var model = new kendo.observable({
    dataSourceType: dataSource,
    Id: 2
});
kendo.bind($("#type"), model);

And then you should define the HTML as:

<input id="type"
    data-role="bobox"
    data-value-primitive="true"
    data-auto-bind="true"
    data-text-field="Name"
    data-value-field="Id"
    data-bind="value: Id, source: dataSourceType">

$(document).ready(function() {
  var dataSource = new kendo.data.DataSource({
    type: "odata",
    serverFiltering: true,
    transport: {
      read: {
        url: "http://demos.telerik./kendo-ui/service/Northwind.svc/Products",
      }
    }
  });
  var model = new kendo.observable({
    dataSourceType: dataSource,
    Id: 2
  });
  kendo.bind($("#cbox"), model);

});

<script src="http://cdn.kendostatic./2014.3.1119/js/kendo.all.min.js"></script>

<input id="cbox"
       data-role="bobox"
       data-value-primitive="true"
       data-auto-bind="true"
       data-text-field="ProductName"
       data-value-field="ProductID"
       data-bind="value: Id, source: dataSourceType">

You can achieve like this.

var bobox = $("#kendoitems").data("kendoComboBox");
bobox.select(1);

you need to pass the index value to select(index).
