DelegateCommand<T>(Action<T>)
Initializes a new instance of the DelegateCommand<T> class. Using this constructor to initialize the DelegateCommand results in a command that can always execute.
public:
DelegateCommand(Action<T> ^ execute);public DelegateCommand (Action<T> execute);new Microsoft.VisualStudio.PlatformUI.DelegateCommand<'T> : Action<'T> -> Microsoft.VisualStudio.PlatformUI.DelegateCommand<'T>Public Sub New (execute As Action(Of T))Parameters
- execute
- Action<T>
The action to run when the command is executed.
Applies to
DelegateCommand<T>(Action<T>, Predicate<T>)
Initializes a new instance of the DelegateCommand<T> class.
public:
DelegateCommand(Action<T> ^ execute, Predicate<T> ^ canExecute);public DelegateCommand (Action<T> execute, Predicate<T> canExecute);new Microsoft.VisualStudio.PlatformUI.DelegateCommand<'T> : Action<'T> * Predicate<'T> -> Microsoft.VisualStudio.PlatformUI.DelegateCommand<'T>Public Sub New (execute As Action(Of T), canExecute As Predicate(Of T))Parameters
- execute
- Action<T>
The action to run when the command is executed.
- canExecute
- Predicate<T>
The function to evaluate whether this command is executable. If this parameter is null, the command is always executable.
Applies to
DelegateCommand<T>(Action<T>, Predicate<T>, JoinableTaskFactory)
Initializes a new instance of the DelegateCommand<T> class.
public:
DelegateCommand(Action<T> ^ execute, Predicate<T> ^ canExecute, Microsoft::VisualStudio::Threading::JoinableTaskFactory ^ jtf);public DelegateCommand (Action<T> execute, Predicate<T> canExecute, Microsoft.VisualStudio.Threading.JoinableTaskFactory jtf);new Microsoft.VisualStudio.PlatformUI.DelegateCommand<'T> : Action<'T> * Predicate<'T> * Microsoft.VisualStudio.Threading.JoinableTaskFactory -> Microsoft.VisualStudio.PlatformUI.DelegateCommand<'T>Public Sub New (execute As Action(Of T), canExecute As Predicate(Of T), jtf As JoinableTaskFactory)Parameters
- execute
- Action<T>
The action to run when the command is executed.
- canExecute
- Predicate<T>
The function to evaluate whether this command is executable. If this parameter is null, the command is always executable.
The task factory for the command. If this is non-null, the command will switch to the main thread before raising the CanExecuteChanged event.
