    I have a multi column combo defined. One column contains standard checkboxes (<input type=checkbox>) How do I get at these checkboxes and their checked state, and indeed for that matter, any value or object in a multi column combo box using javascript?

    Any pointers appreciated

    Many thanks

    Hello Kieran,

    Here is a sample code for this:

    <telerik:RadComboBox ID="RadComboBox1" runat="server" AllowCustomText="true" Width="240px">
                <input type="checkbox" checked="checked" id="chk1">
                <asp:Label runat="server" ID="Label1">
                     <%#DataBinder.Eval(Container, "Text")%>            

    you can get the checkbox and label on the client like this:

    var comboBox = $find("<%=RadComboBox1.ClientID %>");
    for (var i = 0; i < comboBox.get_items().get_count(); i++) {
        var item = comboBox.get_items().getItem(i);
        var checkbox = $telerik.findElement(item.get_element(), "chk1");
        var label = $telerik.findElement(item.get_element(), "Label1")

    Hope this helps.

    Kind regards,

     for (var i = 0; i < sender.get_items().get_count(); i++) {
            var item = sender.get_items().getItem(i);
            var checkbox = item.get_checkBoxElement();
            if (checkbox.checked) {

    I hope this will save someone's time.
