UpdateProgress throws javascript error when contained in a Panel with visible = false

If you put a UpdateProgress control inside a Panel control with visible=false, you will get a javascript error that is cannot find the elements used for the update progress functionality.

Anyone, seen this before and know of a workaround?

I get the same result in a MultiView when the UpdateProgress control is contained in a view that is not the current view.

Thanks,

Ryan

When you set Visible equal to false the HTML contained therein does not get rendered at all. You shouldn't need to explicitly hide the UpdatePanel as it should hide itself unless an Atlas postback is in progress.

If you do need to hid it, set the style of the panel to "display: none" and leave it visible. That way the HTML will be rendered but not shown on screen.

Thanks for the suggestion on display: none. This will work for Panel controls, but it won't work for pages using the MultiView control. I guess I'll have to get rid of MultiView and create several separate panels wnd manually control which one is shown and which ones are diplay: none.
