    i followed the nice example from
    and all works like a charm.

    One little problem i have is the following: ShowDelay on the server for the radtooltipmanager is set to 3000, but it does not seem to work for the tooltip, it shows immediatly.

    Is this due the reason i have the at the client in the mouseover?
    Or am i doing something wrong?

    Thanks in advance!

    Hello Egbert,
    Yes, you are correct, the delay you set using the ShowDelay property of the RadToolTipManager is not applied, because you call the show method of the tooltip explicitly. In case you want to keep the current implementation, you can use window.setTimeout to execute the show method after a specified delay.

    i'm trying to use the setTimeout approach on the .Show() method, as below.  The delay is occuring and then the tooltip loads, but as soon as it finishes loading the attach error is thrown.



    showToolTipCT(element, ftext) {



    var tooltipManager = $find("<%=RadToolTipManager1.ClientID%>");



    if (!tooltipManager) return;



    var tooltip = tooltipManager.getToolTipByElement(element);



    if (!tooltip) {


    tooltip = tooltipManager.createToolTip(element);


    var FinalText = ftext.replace("&apos;", "'")

    Hello Michael Warden,

    The problem comes from the incorrect call to the setTimeout function - please, modify the code in the following manner and test again:


    The problem comes from the fact that you should pass a function as an argument - this means either to define an anonymous one as shown above or declare another one and pass its name.

    There is a problem with the setTimeout method. If you hover the element, then move your mouse away, the tooltip will still appear after the seconds set in setTimeout...
    any workarount?

    Hi jc mag,

    Since you show the tooltip from code and by using its method show(), you should also programmatically decide when it should hide or not show. If you simply need to show it on mouse over and hide it on mouse out you can use the built-in functionality - more about available hide events is available below:

    In the case of showing/hiding the tooltip programmatically from your code you should determine what is the behavior. To prevent the showing of the tooltip in some condition after its show was triggered and before it is displayed, you should handle teh OnClientBeforeShow event and use the args.set_cancel(true) syntax to cancel the show after you check the condition.
