The Broadcast Message Received event is called when a broadcast message from another screen is received.

See Broadcast a Message Via Script for more information about using this event.

Example

Canvas.Shared.BroadcastMessageEventArgs

1
var argument = args as .Shared.BroadcastMessageEventArgs;

See Event Argument Type for more information about EventArgs.

The Close event is called when the screen is closed.

The Controls Initialized event is called after the Initialize event has been fired on the screen and all other controls within.

The Custom Context Menu Action event is called when the custom context menu item is clicked. A Script event ID (configured for each custom context menu item in the Context Menu Items property for the screen or control) is passed in along with other relevant information in the context of the click, for example, facility or point tag, as appropriate.

Example

The following example shows how to use the Custom Context Menu Action event for the CygNet Grid. Substitute Grid1 with your control.

Canvas.Controls.Grid.CustomContextMenuActionEventArgs

When you click on a custom context menu item from a control, Canvas will execute the following function:

• Grid1_CustomContextMenuAction(object sender, EventArgs args)

CustomContextMenuActionEventArgs.EventActionID indicates the Script event ID defined in the Custom Context Menu Configuration dialog box.

}
