    Hi,

    We are using RadScheduler to display a rota. The data per eah date is very minimal. However the page which containc RadScheduler control takes about 12-15 seconds to load completely before on can start working on it. The query which fetches the date is fairly basic and highly optimised. So we don't see any problem there.

    Earlier on load, the control was defaulted to to display data for a month. Then it used to take around 20-25 seconds before a page loaded. But ever since we configured it to display data for 7-days, the time has come down to around 12 seconds.

    What we conclude is that the javascript or html that the control brings alongwith it takes fairly long time to load.

    Is there a way we can reduce the amount of javascript of html that is loaded. Or elase if you think there are other problems, can you just the solution?

    Thanks

    I have this same issue, and it's not a problem with too much being sent down the pipe, but rather, (at least in my case) fetching the calendar items from the server to add them to the Telerik control. I tried putting an Ajax manager on the page and setting the loading panel, but I can't figure out how to make it load asynchronously so the page comes up and the calendar just shows the loading panel icon until the items are fetched. I believe the OP has the same issue though because he's describing the same type of delay we're having, especially related to how many days of information are fetched and how that affects the load time.

    Hello Caleb,

    Using RadAjaxManager as described by you will not bring about any benefit to performance. Also, the rendered html output cannot be reduced (we are considering optimizing it for the future). You may have better performance if you use Web Services. Have you considered this?
