ToolTipML Property

Sets the text used for the tooltip of an action, a field, a factbox, or an activity button.

In the client, tooltips appear when you point to caption of the control.


The support for using the ML properties, such as CaptionML and TooltipML, is being deprecated, so it is recommended to refactor your extension to use the corresponding Caption or Tooltip property, which is being picked up in the .xliff file. For more information, see Working with Translation Files.
