Within a callback I use dp.UpdateWithMessage("Test"), and it displays the Message as expected.
I can remove the message by clicking the cross but I want it to auto hide itself. Solutions such as
1, Allow configurable timeout for it to hide itself, say 1 second,
2, Access to the MessageBox using Javascript on afterrender
3, Have any subsequent callbacks reset the Message,
4, Server code to force hide on callback, for example dp.HideMessage() or simular.
