If the UseCommandManager property is set to true, a function whose name is specified by the CommandAttribute.CanExecuteMethodName property manages whether the command can be executed.

See the example below:

C#

public class LoginViewModel {
        [Command(CanExecuteMethodName = "CanSaveAccountSettings",
            Name = "SaveCommand",
            UseCommandManager = true)]
        public void SaveAccountSettings(string fileName) {
            //... 
        }
        public bool CanSaveAccountSettings(string fileName) {
            return !string.IsNullOrEmpty(fileName);
        }
    }
