New Post: Resharper 7 Support?

tonysneed — Thu, 02 May 2013 14:14:53 GMT

I'm a huge ReSharper fan, and this sounds like a great idea. I'll add this to the feature list for the next rev.

New Post: Resharper 7 Support?

Ruhrpottpatriot — Tue, 30 Apr 2013 17:01:39 GMT

Hey there!

ReSharper7 offers a great way to implement properties with the INotifyChanged interface, as seen here: http://blogs.jetbrains.com/dotnet/2012/07/inotifypropertychanged-support-in-resharper-7/#comments

I know that this toolkit offers a code snipper for that, but If I have a class (or multiple classes with many properties it soon becomes tedious work to type mvvmprop, hit tab and then change the property to my liking.

With Resharper7 and Caliburn.Micro I could write all my fields, select them, hit Alt+Ins and let ReSharper do the rest, much more comfortable.

Sadly Resharper does not offer this functionality for this toolkit. However I am understanding that the NotifyPropertyChanged method only has to be decorated with the [NotifyPropertyChangedInvocator] attribute (as described in the article) and the support would be there.

This is a feature I'd gladly see in this toolkit. Is this possible?

New Post: passing multiple selected items from grid view to viewmodel

rlcrews — Fri, 19 Apr 2013 14:30:54 GMT

Tony,

Could you (or anyone else for that matter) provide some insight on the best way to pass multiple selected items from a WPF grid view into a view model. I have tired using Interaction.Behaviors but with no luck. I can't seem to get any selected event to trigger within the VM.

Cheers

Hi,

Sorry my bad. We just need to make sure that the String token match. When Registering to receive, just make sure that the token is "Character" instead of "Char". It should work.

Anyway. glad to know that you worked it out.

Nevermind, I found it out myself. If I get back home I'll post a complete step-by-step guide how to do this. Maybe Tony is so nice and puts this into the programming reference so other beginners won't ahve the same problem (I looked up the discussions and found quite a number of topics about this).

BTW: Great Framework Tony. Thumbs up

New Post: Pass the content of a ListBoxSelectedItem/SelectedValue to the service agent

Ok, that seems straightforward. However, if I include your sample in my project I get the following error:

Expected a method with the 'void NotificationEventArgs<Character> e' signature

New Post: Pass the content of a ListBoxSelectedItem/SelectedValue to the service agent

shakyad — Mon, 15 Apr 2013 02:39:13 GMT

In the receiving end, I would write a method with a signature:

        void CharacterManipulationMethod(object sender, NotificationEventArgs<Character> e)
        {
             var incomingCharacter = e.Data;

        }

You can then do anything with this incomingCharacter or just have this assigned to a property in this viewmodel of type "Character"

so your constructor will look like:

        public SingleCharacterViewModel()
        {
            RegisterToReceiveMessages("Char", CharacterManipulationMethod);
        }

Hope this helps.

That works splendid. Thank you. However is there a possibility to only change the SelectedCharacter property if the selected item has been double-clicked?

Hi,

The idea is to have two property in the viewmodel.

ObservableCollection<Character> Characters
Character SelectedCharacter

Now,

Bind the Characters as a ItemSource of the ListBox and design the ListBoxItem to display the character
Bind SelectedItem of the ListBox to the SelectedCharacter Property
Bind the Datacontext of the Detail section and bind the individual item to the property of the Character.

So, when you select an item, the detail will automatically display the details.

hope this helps.

Ok, I guess I Understand what to do. I still got another problem tough.

How can I send the data from the ListBoxSelectedItem to the ViewModel?

New Post: Pass the content of a ListBoxSelectedItem/SelectedValue to the service agent

rlcrews — Sun, 14 Apr 2013 04:16:20 GMT

You can do this using the MessageBus within the toolkit. If you look in the documentation under code reference you can see some samples. I've done this exact process of passing data between view models and it is pretty straight forward. There may be some code samples. Post back if you need an example but I think you will be able to figure it out from the documentation.

Ok, maybe the heading is a bit misleading. I'll try to elaborate it further.

Currently I have toll which saves the player characters of my RPG group. Those characters are displayed in a ListBox. This i got working with no problems. Every character is showing up fine so far.

The problem I have is the following.
If I double click on a character in the ListBox I want to populate a detail view on the right side of the window.
However to do that I somehow have to get the text of the selected item from the list box into the code behind.
The ListBox on the left and the detail view on the right are two separate views and view models.

My question is: How can I select a character from the ListBox on the left side and pass it to the detail view on the right side.

Greetings

Unfortunately, the only sample code I wrote was in C#. But I believe there are tools to help port C# code to VB.NET.

New Post: How can I browse the SimpleMvvmToolkit-WPF source code from a sample WPF project?

Enjoy. Please let me know if you have any questions on the toolkit. Cheers, Tony

New Post: How can I browse the SimpleMvvmToolkit-WPF source code from a sample WPF project?

TP — Thu, 14 Mar 2013 04:50:49 GMT

To answer my own question:

I needed to change the Project properties of SimpleMvvmToolkit-Common & SimpleMvvmToolkit-WPF by turning off the "Signing > Sign the assembly" option. I then removed their "assembly" references from my SimpleMvvmToolkit-Wpf Project and instead added References to their entries within the Solution > Projects section.

Rebuilding the solution solved my problem and I am now able to see the source code to the SimpleMvvmWpf toolkit from within my SimpleMvvmToolkit-Wpf project.

New Post: How can I browse the SimpleMvvmToolkit-WPF source code from a sample WPF project?

TP — Thu, 14 Mar 2013 04:24:17 GMT

I just installed "Simple MVVM Toolkit v4.0.0.0" and using Visual Studio 2012 I created a SimpleMvvmWpf project. In order to learn how the toolkit works (after reading all the docs except admittedly only quickly skimming the "Programming Reference"), I started exploring. But say I'm in CustomerViewModel.cs:

  public class CustomerViewModel : ViewModelDetailBase<CustomerViewModel, Customer>

I want to be able to highlight ViewModelDetailBase and hit F12 to view its source code. But then I only see metadata not the actual source code.

The documentation Introduction says:

The helper classes are located in the SimpleMvvmToolkit assembly, which you can reference from your project, or you can if you wish include the SimpleMvvmToolkit project in your Visual Studio solution, which is probably a good idea when you are getting to know the framework.

I extracted C:\Program Files (x86)\SimpleMvvmToolkit_2012\Source\SimpleMvvm-Source.zip to my separate VS2012 projects folder. Using Solution Explorer, I then added via the "Add > Existing Project" command:

SimpleMvvm\WPF\SimpleMvvmToolkit-WPF\SimpleMvvmToolkit-WPF.csproj
SimpleMvvm\Common\SimpleMvvmToolkit-Common\SimpleMvvmToolkit-Common.csproj

But that didn't seem to help? I tried building the solution but then get the following error:

Error 1 Cryptographic failure while signing assembly 'SimpleMvvm\Common\SimpleMvvmToolkit-Common\obj\Debug\SimpleMvvmToolkit-Common.dll' -- 'Error reading key file 'SimpleMvvm\Common\SimpleMvvmToolkit-Common\SimpleMvvm.snk' -- The system cannot find the file specified. 'SimpleMvvm\Common\SimpleMvvmToolkit-Common\CSC SimpleMvvmToolkit-Common

So my question is, how can I browse (and eventually even step into while debugging) the SimpleMvvmToolkit source code from within a SimpleMvvm WPF project?

New Post: Silverlight Test

tonysneed — Tue, 12 Mar 2013 21:15:42 GMT

Version 4.0 of the toolkit no longer includes the Test project when creating a RIA Service solution. It turns out Silverlight testing framework is classified as experimental and not supported by Microsoft, so I had to remove it from the current version
of the toolkit. However, there is nothing to stop you from adding it yourself. Sorry about that. Cheers, Tony

New Post: Silverlight Test

yanira — Tue, 12 Mar 2013 13:23:42 GMT

Good afternoon everyone!

I am building a Silverlight MVVM app that uses RIA Services using Visual Studio project template installed by the Simple MVVM Toolkit. The problem is when I get the solution because "Silverlight Test" project doesn't appear in the solution. I installed Simple MVVM Toolkit correctly.
Why doesn't appear?

Thank!!!
