    I have a ToolTip that is set to Modal with the ShowEvent and HideEvent both set to FromCode.  Is there a way to determine if the ToolTip is showing in the CodeBehind?

    Hi Steven,

    The RadTooltip works on the client and only client-side actions can triggers its showing, so there isn't a straightforward way to see if this is has been opened.

    What you can try is getting a reference to the currently shown tooltip (see how to do it here) and store its ID, class, target ID (or any other data) in a hidden field that will be posted on the server so you can obtain the information there. If there isn't data then no tooltip has been shown when the postback has been initiated. The window.onbeforeunload can be useful for full postbacks and the PageRequestManager beginRequest for partial ones.

    All the best,
