I am loading a gridview using a code based on this:

http://msdn.microsoft.com/en-us/library/ms366515%28v=VS.80%29.aspx

I am using callbacks to populate the grid, sometimes there is a lot of data or the user wants to cancel.

How can I cancel the callback from being processed on the server when user hit cancel??

thanks

    AFAIK, you cannot cancel the server side call back processing once initiated. At the most, you can have some client (browser) side logic that will ignore callback results.

    Regardless, I will suggest you to use ASP.NET AJAX (UpdatePanel or Script Services) rather than using ICallbackEventHandler. It’s quite simple to use and more flexible. Besides, you also have options such as cancelling callbacks : see this article for cancelling update panel callback (note that cancel really means stop waiting for (& ignoring) callback results, the server side processing would happen).
