It seems that after first load devexpress "resources"(themes, assemblies) are cached and the applications calls their instances much faster over time. Please show how to preload all needed resources during startup(while showing splash screen for example).
Thank you.
Slow first call of window with devexpress controls on it

Hello Tea,
Thank you for the question. We have attached a sample to the following thread: How to use the DXSpashScreen window while loading the main window. Please try it, this sample should help you. I am looking forward to hearing from you.
Thank you, Marina
Hi Marina,
is there any chance to do the loading of themes etc. in a seperate thread?
My problem is, that my application "hangs" for 2 or 3 seconds while show/hide that testform.
Thank you for your help!
Hello,
I am afraid that showing the test form in a separate thread will not help speed up the first loading, because the main form should be opened after the test form.
In fact, each window in WPF already uses a separate UI thread, so in your case I can only suggest you create several test forms and open them simultaneously.
