ultrawebtree does not cancel postback
posted

When I run this app and click on a node, a prompt asks me if I want to continue.  If I click on 'Cancel', the POSTBACK stops as intended.  If I click on 'OK', the POSTBACK continues as it should.  However, once if I click on any nodes and I try cancelling the POSTBACK by clicking on 'Cancel', the POSTBACK continues!!  Why?  What am I doing wrong in this app??  Thanks for your help.

See app below:

    Hi mrjdavilla,

    I know it has been a while since your post but in case you are still in need of assistance I would be glad to help.

    I investigated your scenario but was unable to spot any issues with your implementation. Here is the slightly modified javascript function I used:

    

    function tvwDevices_BeforeNodeSelectionChange() { 
            var changesMade = 'true' ; 
            if (changesMade == 'true' ) {var confirmLeave = window.confirm("You have unsaved changes. \n \n Are you sure you want to continue?"); }

            if (confirmLeave) {

            return false; 
           } 

            return true;

    }

    Please do not hesitate to contact me if you have any questions.

    Best Regards,
