    hi,
    I have a splitter with three panels. "Left" and "middle" can be expanded/collapsed while the right is fitting whole free space.
    Everything is fine untill right panel containce the grid with about 50 rows. after that splitter thinks about 3-10 sec before doing collapse stuff.
    Any solutions to speed it up? I'm using VisibleDuringInit="false" and LiveResize="false" but it still isnt enough.

    thanks

    Hi Leonid,

    I built up a test demo and examined the performance with the 2008.3 1314 version of Telerik.Web.UI but I could not reproduce the problem. Would you please make sure that you are not using an older version - if so, upgrade to the latest available build and test again. I also attached my test demo - in case you are able to modify it in order to reproduce the issue, please modify it, open a new support ticket and send it to me along with detailed explanations.


    All the best,

    Leonid,

    How did this one go? Did you get it resolved? Was it something in your code causing the problem?

    hi Stuart,

    Unfortunately I didnt get solution for this problem. Teteric advice was to set debug="false" in the webconfig :) It didnt help of course.
    And the problem occurs only in IE, in Chrome it works quite fast.

    Regards,
    Leonid

    Hi guys,

    Please, let me shed some light on the dicussed problem.

    Leonid, we suggested to set debug=false because this for sure reduces the time the scripts need to execute. Even if it did not solve the problem it has improved the performance and probably there is an additional reason for the issue. However, in the mentioned support thread at last we have sent you a video capture of the results on our side and we never get any feedback, video capture, information, details, etc from you and that is why we could not know whether you fixed the problem or there is further investigation needed and if so, there was no available additional information from you to base it on. Furthermore, in the other thread the significant slowing down came from your custom skin and after we disabled it we could not reproduce the described big delay as shown in the attached video capture there.

    Stuart, what we can suggest you that might solve the problem is the following:

    1. Upgrade to the latest version of RadControls if you haven't - the performance is continuously improved and it is possible that it is better in this version compared to an older one.
    2. Set debug="false" in the Web.config file.
    3. Reduce the HTML contained in the splitter as much as possible - e.g enable paging for the grid, etc.
    4. Use AJAX where possible.
