okay thank you Ward,
I was a little off track from the readme, but no problem though. I will first read about these dependency properties to be sure what I'm doing. I want to learn about any performance penalties too, so there is much ahead.
Thanks again.]]> Mon, 23 Nov 2009 11:29:08 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1561&PID=5852#5852 Prism explorer and prism or infrastructure commanding : Hi Niels - I just re-read your... http://www.ideablade.com/forum/forum_posts.asp?TID=1561&PID=5847#5847 Author: WardBell

Hi Niels - I just re-read your post and realize that you found that example. That is the Prism way as I understand it. Please post again here if there is something specific about my example that I can explain better.]]> Fri, 20 Nov 2009 16:25:04 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1561&PID=5847#5847 Prism explorer and prism or infrastructure commanding : Sorry for the delayed response.... http://www.ideablade.com/forum/forum_posts.asp?TID=1561&PID=5846#5846 Author: WardBell

Sorry for the delayed response. I didn't see this for some reason.

One of the deficiencies of the Prism commanding approach is that they only wired it for Buttons. However, they do describe how you can extend commanding to other control events.
 
There is an example of that in Prism Explorer. Take a look at Infrastructure.Commanding.SelectionChanged and SelectorSelectionChangedCommandBehavior.
 
Then look at its usage in the module, ModelExplorer.Explorer.ExplorerView.xaml. Around line 278 you will find a binding of a ComboBox.SelectionChanged event to this command.
 
Use that as a model to come up with your own command behavior for binding to the TextBox changed event.

Hello,

I'm recreating a Silverlight test project from the Prism explorer example. In that I need a Prism event/command from TextBox change.

In your example I can see reference to cal:Click.Command from a button, but in a combobox you use another method: infrastructure:SelectionChanged.Command

I wanted to use the Prism way, and expected so because your readme file in the Infrastructure project says that they are no longer used. It rather seems it is used, but I would like to know how it would be possible in the Prism way.

Any help is much appriciated.
