New Post: canExecute problem

Iluha — Tue, 16 Nov 2010 05:12:38 GMT

Hello!

I have a problem with CanExecute logic and CommandBehaviorBase.

For example, in your Sample project in MainViewModel class there is ICommand TextChangedCommand.

I changed this property a little :

public ICommand TextChangedCommand
{
get
{
if (textChangedCommand == null)
{
textChangedCommand = new DelegateCommand<TextChangedEventArgs>(OnTextChanged, (args) =>
{
if (System.DateTime.Now.Second < 30) return true;
else return false;
});
}
return textChangedCommand;
}
}

I added CanExecute logic. This logic work properly when CanExecute return true and begin to return false.

But when CanExecute begin to return true the control (TextBox) is still disabled.

RaiseCanExecuteChanged() don't resolve problem.

Any suggestion please.

Thanks.

currently its only for WPF... as for the difference, the main thing is that CoreMVVM isnt the ultimate library that tries to solves all your MVVM scenarios. Rather it provides a few helper that addresses about 60-70% of the scenarios and this allows the user understand the concepts better. This is a stepping stone to more complicated and fuller frameworks

Cool nice one Lester. I can only think having lots of MVVM choices out there is a good thing for most folk. Excellent.

Thanks for updating the text though.Cinch used bits from other places too, so it's no big deal.

Thanks Sacha. The code is derived from Cinch. Have updated the credits on the project description. Thanks for pointing it out.

Good job, I like it. It is very simliar to what my own MVVM framework does. It's called Cinch and can be found at

http://cinch.codeplex.com/

The core services and your ViewModelBase class look very very similiar to what I do in Cinch.
