Hi,
I we are having a problem with the UltraComboEditor, the first time i drop down a combo it takes from 3 to 5 seconds on my machine (a quad core) and like 10 in other test machines. It hangs the UI so something is running in the main thread.
It seems to happen only the first time you dropdown any combo inside the application and its about the same time with 3 or 3 thousand items.The slowdown is somewhere between BeforeDropDown and AfterDropDown.
I guess it is loading some static resources for all the dropdowns but i would like it to do that on my application pre-load method. Any guess what it may be doing? And if i am true how can i force it to preload those resources on demand?
I know it may seem trivial but it is not, we are working hard to have the best user-experience possible and those things are odd.We are using netadvantage 10.3
[Edit] We are compiling targeting x86 platform due to the debugger issues on a 64bit system. [/Edit]
Thanks in advance.Aridane Álamo.
Hi Aridane,
Is there anything further that we can help you with regarding this issue?
Mike Bowshewicz"] Hello Aridane, Could you please provide a sample project showing this behavior? We can use the sample to narrow down the cause of the long load times. Thanks.

Sorry but we are using a large application framework where controls are configured deppending on the ORM schema and Binding attributes so its hard to build a demo-project with source, on the other side it slowdowns deppending on the system.I tested in my home computer (quad core) and had the slowdown, but in my laptop (dual) didn't.Also it is not a problem with quads because in the testing computer (a quad) it works perfect.Anyway the precompile thing and some other tweaks in the framework has solved it.
Thanks.
Sorry, i was in another project and couldn't try your solution until now.
It works, i prepared all the infragistics assemblies in Main and now loads much faster. Also optimized some code that needed refactoring.
The long loading time was caused by the JIT but also we where instantiating more than one spell-checker in the same form programatically.
Thanks for the help, problem solved.
Hello,
Do you require any further assistance with this issue?
