    Hi all.
    I have a simple scenario. On left i have a radtreeview and on the right the content of the page. On page load in the content area i load a default usercontrol. When I click on node in the treeview, using radajaxmanger the content area is changed to some other user control. The problem is now that, when I have e.g. a radgrid on this user control (with radajaxmanagerproxy), I can't change e.g. page number, because the entire update panel is refresed to the default one view, which I load on page load.
    I tried to disable the ChildrenAsTrigger attribute in the AjaxSettingCreated, but it results only in that, the updatepanel is not reloaded to the default view. Paging not working. How can I fix that?

    A simple reproduction:

    Hi Łukasz,

    The problem is not in the Ajax, you can actually remove the Ajax manager, or set EnableAjax=false, and you will see that it behaves the same way.

    The problem is that you reload the RichContent during click on the menu. And in case the post back is initiated from the grid, you don't add it. So if the post back is not from the menu, your grid is missing.

    You need to always load the same user controls. But for example change their Visible property when they should not be visible.
