Default select kendo combobox

Question

I use KendoUI ComboBox and I want to put a default select item.

In KendoUI ComboBox I didn't find the way to put the default value in text and not with index.

<script>
    $("#combobox").kendoComboBox({
        dataSource: [
            { id: 1, name: "Apples" },
            { id: 2, name: "Oranges" }
        ],
        dataTextField: "name",
        dataValueField: "id"
    });

    var combobox = $("#combobox").data("kendoComboBox");

    combobox.select(combobox.ul.children().eq(0));
</script>

Here is the example. How can convert it to put text?

Answer 1

As @SatyaRanjanSahoo says you should use value but you should use the id value otherwise you will be forcing a value that might not be in the DataSource.

Example, If you do:

var combobox = $("#combobox").data("kendoComboBox");
// Set Value
combobox.value("Apricot");
// Get Value
alert("Value is " + combobox.value());

this will show Apricot but this is not in the DataSource meanwhile, if you do:

var combobox = $("#combobox").data("kendoComboBox");
// Set Value
combobox.value(2);
// Get Value
alert("Value is " + combobox.value());

This will show Oranges that is the correct value for the item which id is 2.

So, unless you are sure that the value set in value call is a valid dataTextField I would recommend using the dataValueField.

Check this in the following code snippet...

$("#combobox").kendoComboBox({
  dataSource: [
    { id: 1, name: "Apples" },
    { id: 2, name: "Oranges" }
  ],
  dataTextField: "name",
  dataValueField: "id"
});

var combobox = $("#combobox").data("kendoComboBox");


// Set a valid value
combobox.value("Oranges");
alert("Value for Oranges is: " + combobox.value());

// Set an invalid value
combobox.value("Apricots");
alert("Value for Apricots is: " + combobox.value());

<input id="combobox"/>

Answer 2

To put text directly into combo-box:

 var combobox = $("#combobox").data("kendoComboBox");
 combobox.value("Oranges");

But, using the same approach anonymous text can be set into the combo-box which is not a part of the data-source. i.e.

  combobox.value("XYZ");

So, its good to use index to set value to combo-box.
