Inheritance HierarchyNamespace: TomsToolbox.Wpf
Assembly: TomsToolbox.Wpf (in TomsToolbox.Wpf.dll) Version: 2.21.0+44d18b541fc9419ec3c549350a832394661b2a4d

SyntaxType Parameters
- T
- The type of the command parameter.
The DelegateCommand<T> type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
  | DelegateCommand<T>() |
Initializes a new instance of the DelegateCommand<T> class.
No callback is initially set, so they must be set via the property setters. This usage generates easy readable code even if the delegates are inlined. |
| DelegateCommand<T>(Action<T>) |
Initializes a new instance of the DelegateCommand<T> class with the execute callback.
This version generates more compact code; not recommended for in-line delegates. |
| DelegateCommand<T>(Predicate<T>, Action<T>) | Initializes a new instance of the DelegateCommand<T> class. |
Properties| Name | Description | |
|---|---|---|
 | CanExecuteCallback | Gets or sets the predicate to handle the ICommand.CanExecute method. If unset, ICommand.CanExecute will always return true if ExecuteCallback is set. |
| ExecuteCallback | Gets or sets the action to handle the ICommand.Execute method. If unset, ICommand.CanExecute will always return false. |
Methods| Name | Description | |
|---|---|---|
| CanExecute | Defines the method that determines whether the command can execute in its current state. |
| Execute | Defines the method to be called when the command is invoked. |
Events| Name | Description | |
|---|---|---|
 | CanExecuteChanged | Occurs when changes occur that affect whether or not the command should execute. |
Extension Methods| Name | Description | |
|---|---|---|
 | SafeCast<T> |
Performs a cast from object to T, avoiding possible null violations if T is a value type.
