Good Morning,
I recently pushed a version of my app out for UAT. Apparently one of the testers was experiencing a cpu spike when working with the ultra combo's in the application. I originally contributed this to the multi threaded design of the application and began to research where cross thread calls may occur as well as other avenues for memory leaks. After much research I have found that the issue lies with the way the ultracombo is used within our application. We have a mdi application that takes use of the ultracombo in several child forms as well as user controls. I tried to recreate the issue with a new project by simply adding a combo box and a simple datasource (array list). To no avail, all was well with the test project. With a little more effort, I added the combo to a user control and then added a ultradockmanager to the main form. I then docked the user control within the parent form and tested again. I was able to recreate the issue. When the combo is used on a child form or usercontrol much like I am doing, when the user simply clicks the combo, the processor spikes. Any Ideas?
From what you've said I don't see any relation between "processor spikes" and possible memory leak. High processor usage can be caused by very different things, and memory leak is probably the least logical explanation. Try to profile your application with a profiler (ANTS Profiler or dotTrace. Free trials are downloadable) and post the results here.
Any idea when this is going to be resolved. My tech support on this was lowsy and the case was inevitably closed. I am trying to be polite on this one, but how about a little effort!

Hi,
If you beleive your case was closed in error, you should respond to developer support and ask them to re-open it. I have forwarded this thread over the Developer Support and asked to take a second look.
dward1982,
I believe I've found the support case in question, case number CAS-16799-2IBU2P.
From what I see, you'd sent us a sample and steps, yet when the Developer Support Engineer followed these steps he didn't see the behavior you'd described.
I also see a note that you'd tried attaching a vsp (in .csv format) to the case. We never received it, and didn't receive a response back when we provided an alternate means to send us the file.
Since this case was closed within the past 30 days, it's possible to reopen it, and I've done so for you already. Please attempt to attach the file you'd mentioned again - you should compress it in .zip format to make sure that our system will accept it. If you can't attach the file, please either attach it to this forum thread or send it in an email message to support@infragistics.com (put the case number in the header).
