-> ICommandBinding[] Parameters
- source Object
- The source object, whose property specified by the sourcePropertyName parameter is observed.
- sourcePropertyName String
- The name of the source property, whose change is observed.
- target Object
- The target object, whose property specified by the targetPropertyName parameter is observed.
- targetPropertyName String (Optional)
- The name of the target property, whose change is observed. If ,
then it is considered as the same as sourcePropertyName. This parameter is optional.
Default value: . - format FuncObject, Object (Optional)
- If not , then can be used to format the value to be set in the target object. This parameter is optional.
Default value: . - parse FuncObject, Object (Optional)
- If not , then can be used to parse the value to be set in the source object. This parameter is optional.
Default value: .
Return Value
ICommandBindingThe created pair of ICommandBinding instances.
