[Solved] AdvanceEditTemplate:Client side validation for overlap appointments

[Yelena]

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.
