WPF tuto’s – Forward commands

With the MVVM pattern, it’s quite difficult to handle context menu commands because context menu are not in the same tree view and we generally don’t want to bind on business commands that are in menu item view models. It’s the same problem for tool windows and so on, because we want to reuse the existing commands.

I describe below the “Forward” command pattern used in CBR. Note that MVVM is implemented via MVVMLight.

First, extend your ViewModelBase to have a ViewModelBaseExtended that will implement a ForwardCommand for all your view models. With also an overrideable method GetForwardCommandContext

CommandContext is an helper class that will contain the command to execute as string and an additional command parameter

#region ----------------COMMANDS----------------

private ICommand forwardCommand;
 public ICommand ForwardCommand
 {
 get
 {
    if (forwardCommand == null)
            forwardCommand = new RelayCommand<string>(
  delegate(string param)
  {
     Messenger.Default.Send<CommandContext>(GetForwardCommandContext(param),
           ViewModelBaseMessages.ContextCommand );
  },
  delegate(string param)
  {
    return CanForwardCommand(param);
  });
  return forwardCommand;
  }
 }

protected virtual CommandContext GetForwardCommandContext(string param)
 {
 return new CommandContext();
 }

protected virtual bool CanForwardCommand(string param)
 {
 return false;
 }

#endregion
 }

public class CommandContext
 {
 public string CommandName { get; set; }
 public object CommandParameter { get; set; }
 }

UWP : New C.B.R.

Hi all,

I am writing a new version of C.B.R for Universal Windows Platform. I start from the ground with a MS sample Lunch scheduler (https://github.com/Microsoft/Windows-appsample-lunch-scheduler) and hope this new version will be available under 2 or 3 months…

I will write a few articles about trouble i have with my solutions like customize the title bar and the full screen mode because it is quite hard to find help and tips about this new platform.

Improvments : I will do it like “Groove” : give a folder, and CBR will create catalogs and books for you. No more need to create everything by hand
