Filter DataSource Manually

The Kendo UI ComboBox has a built-in detection mechanism that checks whether the data is filtered or not.

This information is used by the widget to decide when to persist the selected value that does not exist in the source. When the source is manually filtered, the ComboBox loses the details about the state of the Data Source and, as a result, might fail to operate.

The following example demonstrates how to manually filter the Data Source instance of the Kendo UI ComboBox.

<div id="example">
    <div class="demo-section k-header">
        <select id="combobox"></select>
        $(function() {
            var combobox = $("#combobox").kendoComboBox({
                dataTextField: "name",
                dataValueField: "value",
                dataSource: {
                    data: [{ name: "One", value: 1 }, { name: "Two", value: 2 }]

            //Filter the source manually
                field: 'value',
                operator: 'eq',
                value: 1

            <!-- IMPORTANT: Update filter state of the widget -->
