Interface ICommandContext
Describes the context in which a Command is being invoked. When a Command is invoked via InvokeCommand(Command) a context object is passed to Command handlers as an ICommandContext reference.
public interface ICommandContext- Extension Methods
Properties
- Binding
The binding that triggered the command.
- Routing
Gets the routing mode for this command invocation.
- Source
A weak reference to the View that was the source of the command invocation, if any. (e.g. the view the user clicked on or the view that had focus when a key was pressed). Use
Source?.TryGetTarget(out View? view)to safely access the source view.
- Value
Gets the most recently appended value from Values, or null if Values is empty. This is a convenience accessor equivalent to
Values.Count > 0 ? Values[^1] : null.
- Values
Gets all values accumulated as the command propagated up the view hierarchy. Each IValue-implementing view in the chain appends its value via GetValue() as the command bubbles up. The list is ordered from innermost (originator) to outermost (last composite to append).
