D'ooh

[Marco Bertschi]

Started a pet project last weekend. I want to have a wizard control which just sucks up user controls and displays them in a given order with a given title in the side bar. I know something like that alread does exist on CP, but I 1) Want to make one on my own. My time, don't tell me what to do with it :laugh: 2) I'm not sure how good the existing one supports page validation. Anyways, I was debugging the first (very raw) build, and for some reason just the first item in the TOC was showing a title:

WizardViewModel model = new WizardViewModel();
model.WizardTitle = "Test";
model.WizardDescription = "Ein schlecht gestylter Beispiel-Wizard.";

        WizardStepViewModel stepmodel = new WizardStepViewModel();
        stepmodel.Name = "Willkommen";
        stepmodel.Content = new Testdata.WelcomeScreen();

        WizardStepViewModel stepmodel2 = new WizardStepViewModel();
        stepmodel.Name = "Wizard-Zeug";
        stepmodel.Content = new Testdata.TestUserControl2();

        WizardStepViewModel stepmodel3 = new WizardStepViewModel();
        stepmodel.Name = "Zusammenfassung";
        stepmodel.Content = new Testdata.EndUserControl();

        model.WizardSteps = new List<WizardStepViewModel>() { stepmodel, stepmodel2, stepmodel3 };

        WizardControl.View.WizardControl ctrl = new View.WizardControl(model);
        this.MainGrid.Children.Add(ctrl);

You see why, don't ya. :doh: :doh:

D'oh indeed. But surely it's just Zusammenfassung that's showing. It's to avoid this type of issue I would normally do something like this:

private WizardStepViewModel GetModel<TModel>(string name) where T : class, new()
{
return new WizardStepViewModel { Name = name, Content = new TModel() };
}

Something like this surely happened to anyone at some point ;) But I have a suggestion for you:

WizardStepViewModel stepmodel = new WizardStepViewModel()
{
Name = "Willkommen",
Content = new Testdata.WelcomeScreen()
};

1, 2, 3, oops. I must say though, it occurs to me that sometimes the MVVM pattern is a bit, well, over the top. When something like (pseudo-codish):

Items items = new Items[] {new Item("foo", control), ...etc...};
MainGrid.Children.Add(items);

where you override Item.ToString() with Item.Name ? BTW, I loathe this. syntax. It's so Visual Basic, I, Me, Me, Mine ;) Marc

Visual...wait burn it with fire! :omg:

WizardViewModel model = new WizardViewModel(
WizardTitle: "Test",
WizardDescription: "Ein schlecht gestylter Beispiel-Wizard.",
new WizardStepViewModel("Willkommen", new Testdata.WelcomeScreen()),
new WizardStepViewModel("Wizard-Zeug", new Testdata.TestUserControl2()),
new WizardStepViewModel("Zusammenfassung", new Testdata.EndUserControl()));

Assuming:

public class WizardViewModel(string title, string description, params WizardStepViewModel[] stepviews) { ... }

I note that you, as author, made the same choice that L. Frank Baum made in "Wizard of Oz:" the WizardControl makes a dramatic appearance from nowhere at the end of the novel. And, nice touch with the suggestion of recursion: WizardControl.View.WizardControl : I assume that's the way things go down in MVVM-land. But, don't let this (deliberately ... perceived by you as playful, I hope) capricious intrusion distract you from the enjoying the current flavour of your omnipotence ... after all, isn't it that taste that makes the drudgery ... of having to behave like robots to get other robots to (kind of) half-do our bidding at the expense of art and grace, and with the cost of our wallowing in endless minutiae ... worthwhile ? :)

I wrote the code on my home PC (which VS Community 2015). The IntelliSense only seems to work if I put this, and I did not really care since it is test code only. (Not test as in Unit-Test, but as in "Test I only want to do to see if it works).

I usually use this, but since it was just write once, run once test code I frankly didn't care at the moment of writing.

Guess so. Usually, at work, R# handles stuff like that for me. Unfortunately said code was written at home, with VS Community 15, and no R#. Software makes us dumb.
