    I have two schedulers embedded in one page.  It is very slow when I try to load the page in IE7. However, the loading speed inside Google Chrome was very fast. My customer doesn't satisfy with the loading speed in IE. Can you help with this?

    Hi Hong Wu,

    Please note that the RadScheduler's performance is like an Achilles’ heel when there are many appointments to be loaded. There are quite a few factors that can affect the performance of RadScheduler in IE. For example, there's a known issue with :hover CSS styles applied on elements different than links that slow down IE to a crawl. For example:
    Copy Code
    .myClass:hover { } // Very slow in IE!!!
    a.myClass:hover { } // Fast - targets a elements only

    The problem is that this doesn't need to be an element in the scheduler itself. Just having the first selector anywhere on the page is enough to bring IE to its knees.

    Could you please be more specific on the following:
    1) Which version of our controls do you use. In the Ticket Info I can see version 2011.1 519. Can you confirm this?
    2) Could you please tell me in which version of IE do you get slow loading?

    Best wishes,
