    Hai,
    As per the design in this page
    http://demos.telerik.com/aspnet-ajax/controls/examples/integration/outlook/defaultcs.aspx
    i have designed a page in asp.net 2008.
    Instead of tree view i placed a asp menu. In its click, Radpane3 is made visible=false.
    This page is a content page & the contents are in an update panel.
    In IE the error is ''_locked' is null'.
    In Firefox the error is Error: _202 is undefined
    Plz Help

    Hello,
    You should not use the Visible property of a RadPane to hide it. Please use the Collapsed property instead.

    All the best,

    Hi,

    I, too, used to use the .visible = false property. By changing it to use the collapsed property the user expereience is not as good as it was. Now when the page is loaded the pane is shown before being collapsed whereas before the pae was never seen by the user.

    How can we ensure that the pane is never shown even for a split-second just ike the visibe property used to?

    Thanks,
    Darren

    Hello Darren,
    You should set VisibleDuringInit="false" for the RadSplitter control. That way, the splitter will remain hidden until all client resize operations are complete.

    Sincerely yours,
