ToolTip / Hide on Event

The HideEvent property enables fine-tuning of when a tooltip will be hidden. You can test it below:





  • RadToolTip's HideEvent

    RadToolTip used to provide ManualClose and Sticky properties which were used to control when the tooltip should hide. These properties are now obsolete and you should use the HideEvent property to control when the tooltip will disappear.
    The HideEvent property is an enum and can take the following values, which names describe the effect when they are set:
    • Default
    • FromCode
    • LeaveTargetAndToolTip
    • LeaveToolTip
    • ManualClose

    Notes

    1. Setting the HideDelay property to a big value will provide the user with more time to move the mouse from target element over the tooltip The default setting is 300 milliseconds (1/3 second)
    2. A tooltip, regardless of its HideEvent setting will hide when a new tooltip is to be shown, because by design there can be only one RadToolTip visible on the page at any give time
