Hello,

I'm tyring with no luck to determine if there is a way to abandon a request that has already been sent to the server.  I am using a menu to load user controls with data, occasionaly one of those user controls may run a query that takes 15+ seconds, if the user clicks on another menu item (rad treeview node) a second ajax request is "queued", and executes after the first one finishes 15 seconds later.

I would like the second menu click to abort the first request and start processing.

is this possible?

thanks,

Hello Stephen,

As I mentioned in the support ticket you have opened for the same issue by default the ASP.NET AJAX Framework cancels the ongoing ajax request if you try to initiate another one prior to receiving the response from the first one. See the help topic below:

Also I have prepared a small video which demonstrates exactly the same behavior:
