Indicates whether returned elements contain full references to the underlying UI, or only cached information.
This property is read/write.
Syntax
HRESULT get_AutomationElementMode(
AutomationElementMode *mode
);
Parameters
mode
Return value
None
Remarks
AutomationElementMode_Full is the default value, and specifies that returned elements contain a full reference to the underlying UI. AutomationElementMode_None specifies that the returned elements have no reference to the underlying UI, and contain only cached information.
Certain operations on elements, including GetCurrentPropertyValue, and SetFocus, require a full reference; attempting to perform these on an element that has none results in an error.
Using AutomationElementMode_None can be more efficient when only properties are needed, as it avoids the overhead involved in setting up full references.
