An object's Control.AccessibleDefaultActionDescription property describes the object's primary method of manipulation from the user's viewpoint. This property should be a verb or a short verb phrase.


Not all objects have default actions, and some objects might have a default action that is related to its AccessibleObject.Value property, such as in the following examples:

  • A selected check box has a default action of "Uncheck" and a value of "Checked."

  • A cleared check box has a default action of "Check" and a value of "Unchecked."

  • A button labeled "Print" has a default action of "Press," with no value.

  • A label or a text box control that shows "Printer" has no default action, but would have a value of "Printer."
