public IDisposable? BindCommandToObject<T>(ICommand? command, T? target, IObservable<object?> commandParameter) where T : class
Summary: Binds a command to the default event on a target object using a generic type parameter.
Type parameters
| Name | Description |
|---|---|
T | The type of the target object. |
Parameters
| Name | Type | Description |
|---|---|---|
command | ICommand? | The command to bind. If null, no binding is created. |
target | T? | The target object. |
commandParameter | IObservable | An observable that supplies command parameter values. |
Returns: IDisposable? -- A disposable that unbinds the command.
Exceptions
| Type | Condition |
|---|---|
| System.ArgumentNullException | Thrown when target is null. |
| System.Exception | Thrown when no default event exists on T and the caller did not specify an event explicitly. |
2. Overload¶
Attributes: [RequiresUnreferencedCode("String/reflection-based event binding may require members removed by trimming.")]
public IDisposable? BindCommandToObject<T, TEventArgs>(ICommand? command, T? target, IObservable<object?> commandParameter, string eventName) where T : class
Summary: Binds a command to a specific event on a target object using generic type parameters.
Type parameters
| Name | Description |
|---|---|
T | The type of the target object. |
TEventArgs | The event arguments type. |
Parameters
| Name | Type | Description |
|---|---|---|
command | ICommand? | The command to bind. If null, no binding is created. |
target | T? | The target object. |
commandParameter | IObservable | An observable that supplies command parameter values. |
eventName | string | The name of the event to bind to. |
Returns: IDisposable? -- A disposable that unbinds the command.
Exceptions
| Type | Condition |
|---|---|
| System.ArgumentNullException | Thrown when target or eventName is null. |
| System.ArgumentException | Thrown when eventName is empty. |
3. Overload¶
public IDisposable? BindCommandToObject<T, TEventArgs>(ICommand? command, T? target, IObservable<object?> commandParameter, Action<EventHandler<TEventArgs>> addHandler, Action<EventHandler<TEventArgs>> removeHandler) where T : class where TEventArgs : EventArgs
Summary: Binds a command to a specific event on a target object using explicit add/remove handler delegates.
Type parameters
| Name | Description |
|---|---|
T | The type of the target object. |
TEventArgs | The event arguments type. |
Parameters
| Name | Type | Description |
|---|---|---|
command | ICommand? | The command to bind. If null, no binding is created. |
target | T? | The target object. |
commandParameter | IObservable | An observable that supplies command parameter values. |
addHandler | Action | Adds the handler to the target event. |
removeHandler | Action | Removes the handler from the target event. |
Returns: IDisposable? -- A disposable that unbinds the command.
Exceptions
| Type | Condition |
|---|---|
| System.ArgumentNullException | Thrown when target, addHandler, or removeHandler is null. |
4. Overload¶
public IDisposable BindCommandToObject<T>(ICommand? command, T? target, IObservable<object?> commandParameter, Action<EventHandler> addHandler, Action<EventHandler> removeHandler) where T : class
Summary: Binds a command to an event using explicit add/remove handler actions (non-reflection).
Type parameters
| Name | Description |
|---|---|
T | The target type. |
Parameters
| Name | Type | Description |
|---|---|---|
command | ICommand? | The command to bind. If null, no binding is created. |
target | T? | The target object. |
commandParameter | IObservable | An observable that supplies command parameter values. |
addHandler | Action | Adds the handler to the target event. |
removeHandler | Action | Removes the handler from the target event. |
Returns: IDisposable -- A disposable that unbinds the command.
Exceptions
| Type | Condition |
|---|---|
| System.ArgumentNullException | Thrown when target, addHandler, or removeHandler is null. |
