If the text button is being displayed for a location, i.e., the UltraNavigationBarLocationSettings.TextButtonDisplayStyle property does not resolve to 'Hidden', the tooltip is displayed when the cursor hovers over the text button. If the text button is not being displayed, the tooltip is displayed when the cursor hovers over the dropdown button.
Note: If the ToolTipText property is not explicitly set, no tooltip is displayed for this location. The UltraNavigationBar.LocationToolTipDisplaying event still fires, however, with the value of the Infragistics.Win.Misc.UltraWinNavigationBar.ToolTipDisplayingEventArgs.ToolTipText property of the event arguments set to an empty string. If a listener of the event sets the ToolTipText property of the event arguments to a non-empty value, that value is then displayed. If upon returning execution from the LocationToolTipDisplaying event the ToolTipText property of the event arguments is empty, or the event is canceled, no tooltip is displayed.
