    I used javascript debugger and did find an object to get the "checked" items in my RadComboBox.
    what is the proper way to do this so I can clean up my code?
    in my case I am getting the list of categories to send to RadScheduler provider

        window.OnClientAppointmentsPopulating = function (sender, eventArgs) {
            var combobox = $find("<%=ddlCatToShow.clientID %>");
            var list = "";
            var items = combobox.get_items();
            var array = combobox._checkedIndices.toString().split(','
            for (var i = 0; i < array.length-1; i++) { 
                var item = items.getItem(array[i]);
                list += item.get_value() + ",";
            eventArgs.get_schedulerInfo().CategoryList = list.replace(/,\s*$/, "");

    Hi Doug,

    The best proper way to get list of checked items in javascript is to call the ".get_checkedItems()" method of your RadComboBox.

    var combobox = $find("<%=ddlCatToShow.clientID %>");
    var checkedItems = combobox.get_checkedItems();
    for (var i = 0; i < checkedItems.length; i++) {
      // Your code here


    More information here : RadComboBox Object.
