PerformAction
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Occurs when the accessibility technology invokes an action.
[token = ]object.AddEventListener("PerformAction", eventhandlerFunction)
Arguments
AddEventListener Parameters
token |
integer A token that is returned from the function, which you can optionally retain as a variable. If you intend to call RemoveEventListener to remove the handler, you will need this token. |
eventhandlerFunction |
object The name of your event handler function as it is defined in script. Quotation marks around the function name are not required. (See the "Remarks" section.) |
Event Handler Parameters
sender |
object The object that invoked the event. |
eventArgs |
object This parameter is always set to null. |
Managed Equivalent
None. The managed API uses an entirely updated accessibility system. See Silverlight Accessibility Overview.
Remarks
You can also add handlers in script by using a quoted string for the event handler name, as follows:
object.addEventListener("PerformAction", "eventhandlerFunction")
This syntax also returns a token. However, the token is not an absolute requirement for removing the handler in cases where the handler was added by using a quoted string. For details, see RemoveEventListener.
