    I have a checkbox defined as

    <telerik:RadButton ID="checkbox1" runat="server" Text="testing" ButtonType ="ToggleButton" ToggleType="CheckBox" OnClientClicked="checkbox1_ClientClicked"></telerik:RadButton>

    What I want to do in the ClientClicked event is only check the box (and uncheck a different checkbox) when the user selects OK. Everything else seems to work fine but even though the last thing I do in the "ok" case is .set_checked(false) the box remains checked. Here is the javascript:

                function checkbox1_ClientClicked(sender, eventArgs) {
                    var checkbox1 = $find('<%=checkbox1.ClientID%>');
                    function CallbackFn(arg) {
                        if (arg) {
                            var checkbox1 = $find('<%=checkbox1.ClientID%>');  // I know I probably don't need this, just being safe
                            var checkbox2 = $find('<%=checkbox2.ClientID%>');
                        else {
                    if (checkbox1.get_checked()) {
                        return radconfirm("warning text", CallbackFn, 330, 150, null, "title");

    I've also tried the ClientCheckedChanged and ClientCheckedChanging events with similar results. What obvious, basic thing am I missing? 8^)

    Hi Harry,

    Please try the below JavaScript to check the CheckBox based on RadConfirm.

    function checkbox1_ClientClicked(sender, args) {
        var confirm = radconfirm("Are you Sure?", callBackFn, 300, 200, null, "Confirm", null);
    function callBackFn(arg) {
        var checkbox = $find("<%=radbtnTestingCheckbox.ClientID%>");

    That worked! The main difference seems to be using 'sender' rather than the object returned from $find, though I would have thought they pointed to the same object. Still new to JS so there's probably a nuance I'm missing. Many thanks!
