<Button IsDefault="true" pf:Message.Attach="SetFilter(_filter.Text)" />

Would be one way.

Unfortunately this does not work in Silverlight where the Button does not have a IsDefault property.

No problem,

Thanks.

I'm having a crazy busy day today. So, I'll get back with an explanation, but might not be until the weekend...

Thanks, that would work.

I'm still interested to know if there is another way to do it though.

Hi,

I have a simple question, I have a filter control with a textbox and a button to apply the filter.

My button click event is attached to the SetFilter method on my view model like this:

pf:Message.Attach="[Event Click] = [Action SetFilter(_filter.Text)]"

I created a KeyDown event handler on my textbox and want to call the SetFilter method when the key pressed is "enter":

        private void _filter_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Key == Key.Enter)
            {
                // Call SetFilter on view model.
            }
        }

How would I achieve this?

Thanks,

Pyt

Thanks, I implemented the first solution, it works great.

I would simply add another property to your root presenter that is the presenter representing your debug panel. Or, you could create a new root presenter and have both your debug presenter and your existing presenter manager as properties on it.

New Post: Presenter Hierarchy Question

pyttroll — Tue, 17 Nov 2009 18:04:57 GMT

Hi all,

I would like to achieve the following user interface

Right now I'm just missing the "debug pane", my root presenter derive from PresenterManager and take care of displaying appropriate content whenever I change tabs.

I want to add a debug pane with its own presenter under my main content, that pane will always be visible. How should I organize my presenters? PresenterManager only has one current presenter as I understand it. Should I derive my root presenter from another class?

Thanks,

Pyt

New Post: Caliburn & Prism & Unity & MEF

EisenbergEffect — Tue, 17 Nov 2009 13:52:11 GMT

Unfortunately I do not have any examples of this. I can tell you that Caliburn should work fine with MEF, you will just need to plug the MEFAdapter into the core during initialization. I believe that there are few blogs posts out there that talk about using MEF + Unity, so you might want to look around for that. Perhaps there is similar information on using MEF + Prism. My guess is that you are probably going to have to piece things together to get exactly what you want. Unfortunately, that is all the help I can give in this area. Please post back here and let us know what you have discovered. I'm sure that this scenario is going to become more common and I would love to have some resources to point other developers to.

Hi Rob

I've built an application around Prism and Unity. I have now encountered quite a few issues you and Jeremy Miller has written about (lifecycle of MVVM triads, coordination of screens), hence my looking at Caliburn.

I have a requirement to modularise my application and rather than use Prisms modularity approach I would like to use MEF.

Do you have any examples of using MEF, coexisting with Unity and Prism?

Thanks
Russell

Caliburn's Prism integration allows you to hook any of Caliburn's adapters into prism. Caliburn's simple container doesn't need an adapter and can be used directly.

Prism has adapter for Caliburn build-in Simple Container?

New Post: Caliburn & Prism & Unity

EisenbergEffect — Mon, 16 Nov 2009 14:26:48 GMT

Using the above configuration technique allows you to use any container that Caliburn provides an adapter for (including the build-in Simple Container). The same container instance will be shared by Prism and Caliburn.

I've done some more investigation into this myself. After reflectoring into the WPF source I found there's a validateGesture parameter to the internal KeyGesture ctor which when true (and it always is true) makes the ctor throw the UnsupportedException when no modifiers are supplied. I pulled this class out and removed the check, then replaced references to KeyGesture in Caliburn with my new one, and low-and-behold it works; seems to be no logical reason this limitation is in there.

Not sure what your thoughts are on this, but for the time being I'm going to run with this modified version of Caliburn.

What is recommend DI container for Prism-Caliburn application?

Is it possible to use Prism with Caliburn internal DI container?
Or Unity is only choice, if you want one DI container for both frameworks in one application?

You don't need to do the mapping if you are sharing the types on both sides. The sample app is getting a bit dated... This is all accomplished for you if you are using Data Services or RIA.
