    DevExpress7.1.2 Has The Efficiency Problem?

    Hi,

    recently, I started to use DevExpress7.1.2 under VS2005 (C#), and it's wonderful.

    But when I run the program called A ( the WinForm Controls in this program are all from DevExpress7.1.2 ), I found problems:

    1.  when run the program A ,it starts very slow (My laptop: CoreDuo,1G),what's the reason?

    2. I maximize the program A 's window, then I drag another program called B keep moving above A , the moving track of program B disappear slowly.  It seems that the DevExpress Controls redraw efficiency is poor,

    3. When I click the Controls in program A, the response is slow.

    4.I learn from this Forum that by writting the following code,we can set the program font easily

    static void Main()
    {
             DevExpress.Utils.AppearanceObject.DefaultFont = new Font("Microsoft Sans Serif", 10);
             Application.Run(new Form1());
    }

    but I found that it has no effect on XtraBar's font

    5.The Above method only can set the Font before the Form initialized, how can I do if I want to change the Font after the program has run. Or if I change the WIndows system's font size, how to change the program's font dynamic?

     

    thanks for your answers,

    regards

    I don't know about the efficiency issues.
     
    The font of the XtraBar items may be set via the DefaultBarAndDockingController.  See the ItemsFont property of the AppearancesBar property of the Controller property of the DefaultBarAndDockingController class.

    The response time is very good for me (I use the latest, but it worked well for me on previous versions too). I suggest you send the solution, or a sample demonstrating the issue, into support.
     
    There are many things that can affect performance. For example, many controls offer BeginUpdate()/ EndUpdate() methods so that they don’t trigger repainting until all changes are complete - certain forms really do need to be optimized.
     
    Guessing your real problem doesn't make sense to me... so... send your project to DevExpress (they honor privacy and respect issues with proprietary code).

    Haven't a clue, I'm afraid. You can either use a profiler to find out,
    or, better, contact support. They'll be able to help you diagnose your
    performance issue.
