Gets or sets the default action description of the control for use by accessibility client applications.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
An object's 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."
For more information about properties of accessible objects, see the "Content of Descriptive Properties" topic in the MSDN library at http://msdn.microsoft.com/library.
