Tracked down the problem:
When i use postback with the notification core i get tons of exceptions. So i assume when using ajax it not a good idea to use postbacks?

Hi Arghad,

Thank you for your interest in Syncfusion Products.

I am afraid that I am not able to reproduce the issue of "On postback tons of exceptions occurs with Window control". Also I have created a simple sample to test this issue and it is available in the following link:


Please have a look at the above sample and if still the issue exists, could you please try reproducing in the above sample and send us the modified sample so that we could sort out the cause of the issue and provide you a solution?
