disabling the kendo combobox deletes the datasource

[subrat]

I am trying to disable the kendo combobox.

    $("#comboBoxid").kendoComboBox({
                                                            enable: false
                                                        });

this makes the _current property and datasource's data property  null.
 $("#comboBoxid").data(constKendoComboBox).current() is null.

How do I stop this? I don't want to delete the data attached to the kombobox.

 I solved it. I am using readonly property now.
var combobox = $("#sourceColumn" + i).data("kendoComboBox");
                                                        combobox.readonly(true);
