'Declaration Protected Overridable Function OnBeforeDisplayToolTip( _ ByVal ultraControl As IUltraControl, _ ByVal element As UIElement, _ ByRef toolTipInfo As ToolTipInfo, _ ByVal trigger As ControlUIElementBase.ToolTipTrigger _ ) As Boolean
protected virtual bool OnBeforeDisplayToolTip( IUltraControl ultraControl, UIElement element, ref ToolTipInfo toolTipInfo, ControlUIElementBase.ToolTipTrigger trigger )
The default implementation returns true unconditionally. This method can be overridden for the purpose of receiving a notification immediately before a tooltip is about to be displayed.
Note: The toolTipInfo structure is passed by reference to prevent a memberwise copy from being made, in the interest of conserving memory; however, no properties of this structure should be modified.
