Programming asp .net core mvc, via VS2017.
Is there a control that can be adapted to provide a non-modal message box, ideally without a compulsory title and which can be positioned in relation to the viewport? By way of example from a current application, I would like to be able to display a message eg 'Customer Successfully Updated', say after a successful Ajax post where the box would appear top-left of the viewport, fade in and fade out automatically after a given time, all without preventing user interaction with the underlying page.
As I read the documentation, Dialog is modal only - I don't want to prevent the user from interacting with the page while the message is displayed.
ToolTip seems to do most of this (I assume it is modeless) but seems to have no way of being launched programatically (ie without a user click, hover, etc.
Any suggestions, please?
