If you set the ShowEvent of the RadToolTip to a value, different than FromCode it will register the appropriate event itself, so it should not be necessary that you do this by hand, as showing the tooltip OnMouseOver will precede the click in any case, so if the HideEvent is set to ManualClose or FromCode a subsequent click on the target element will not hide the tooltip.
