We're experiencing very slow repainting with our winforms mdi app when resizing the mdi container application. We are using the Office 2007 isl files supplied with the App Sylist and the only thing we have changed on this is the default font (to Tahoma)
I've seen a post where it was mentioned that transparent controls can cause this and that might well be the problem for us as we were using a transparent groupboxes on top of a transparent ultrapanel (in order to get app styled scroll bars).
However, I have just turned the transparency and the autoscroll off and I'm still getting the same issues. Could you let me know the best practices for keeping fully styled apps resizing smoothly? What should we avoid and are there any tricks for turning repaint on and off etc.?
Tom,
There are several possible causes for flickering. The first thing I would ask is what type of hardware are you using?
To familiarize yourself with the how infragistics develops Win Form Elements I would suggest reading this http://help.infragistics.com/Help/NetAdvantage/NET/2008.3/CLR2.0/html/Win_PLF_Overview.html
Also, you can achieve app styled scroll bars by using the netadvantage app stylist, granit it, you cannot style Inbox Scroll bars; you still have the option of styling: ScrollBar thumb, scroll bar track and arrow buttons for the infragistics controls.
The link provided above is broken. I guess most of the link referring to articles of previous versions of infragistics are broken. I am having the same issue. Where if I drag any other window (like windows explorer) on top of our application the window becomes invisible with some of the paints visible. As you hover the mouse the window tries to paint itself. I will attach the screenshot soon
