    I use default Advanced/Insert Template.   I would like to do validation for overlap appointments before the postback on the client side.So i try to re-use the code for the LinkButton RadConfirm example.
    On the FormCreated event I added OnClientClick event for InsertButton
    if (e.Container.Mode == SchedulerFormMode.AdvancedInsert) {
        LinkButton formButton = e.Container.FindControl("InsertButton") as LinkButton;
        if (formButton != null)
        {
            formButton.OnClientClick = "confirmLinkButton(this);  return false;";
        }
    }
    and in my Javascript I added
    function confirmLinkButton(button) {
        try {
            alert("confirmLinkButton");
        function linkButtonCallbackFn(arg) {
            if (arg) {
               eval(button.href);
            }
       }
    //   RadConfirm(insertOverlapMessage, linkButtonCallbackFn, 330, 180, null, "Confirm");
       var confirmReturn = confirm(insertOverlapMessage);
       if (confirmReturn) { eval(button.href); }
     
         
    } catch (e) {
        alert(" confirmLinkButton: Error Description: " + e.Description + " Error message:" + e.message);
    }
    }


    BUT  my javascript function never been call and it is really inconvenient to use RadConfirm on the server side after postback :  all data from the insert form have been disappeared.

    Please, advice how I can make the code to work.  Thank you for your help!

    Hello,

     
    You can achieve it with jQuery as for example in the code below:

    function OnClientFormCreated(scheduler, args) {
                   var $ = $telerik.$;
                   $(".rsAdvEditSave").bind({
                       click: function () {
                           if (contition) {
                               return false;
                           }
                       }
                   });
               }

    Hope this will be helpful.
