    I have a RadComboBox with checkboxes and I want to get all the values in the DataValueField as a comma separated string.

    $get("myComboBox").value gets me a comma separated string of the DataTextField and not the DataValueField.

    How do I do this?

    Hi, Max.

    It's actually really simple: you just loop over the checked indices, then push the values inside an array and finally join the array e.g.:

    function getValuesGeneric( combobox ) {
        var values = [];
        var items = combobox.get_items();
        Array.forEach( combobox.get_checkedIndices(), function( element, index ) {
            var item = items.getItem( element );
            values.push( item.get_value() );
        alert( values.join(",") );

    Where as combobox is the client-side object.

    I've also attached a simple page with the code.
