General WPF/MVVM question!

I use a combination of an attached behavior, base class, and dialog service to handle this in a very straightforward way. My base class implements INotifyPropertyChanged as well as providing access to the dialog service, dialog result, and okay and close commands.

The dialog service uses Activate.CreateInstace(typeof(T)) to spawn the window based on method signature: bool? ShowDialog<T>(viewModelBase viewModel). After that it's just setting the dataContext to the viewModel and returning ShowDialog(). Use:
var result = DialogService.ShowDialog<MyWindow>(viewModel); No reference to System.Windows necessary.

The commands get bound to the views buttons and a nifty DialogCloser (http://blog.excastle.com/2010/07/25/mvvm-and-dialogresult-with-no-code-behind/) allows me to close the window effortlessly.

Greenfield is a lot better than undocumented brownfield so you've got that -- I would requisition a new server ( check out TeamCity if you have a budget ) and and get going there. Do you have an issue tracker? That is probably the 2nd most important thing after source control . . ..

I just finished moving almost everything to team city, we were already using Jira. I convinced everyone to start writing their own unit-tests (which apparently some of them were already doing).

Anyways the bad:

Automated integration tests are a mess/non-existant. Some coop student a year ago bravely wrote a ton of integration tests using capybara for the various UI stuff (app uses ASP web interface). With the goal of letting us automate, except he wrote like a grand total of 10 tests and they are so disgustingly monolithic and full of awful awful spaghetti code. He was also the only one who knew ruby.

So for the last year the previous test developer was apparently testing everything manually. Even then people spent 5-6 days just going through a full end to end integration test. Our SOAP and REST API that two clients currently use in their products have never really had an integration test and are constantly falling apart.

Test plans for the majority of projects do not seem to exist, or what we have on file is so stupidly old and outdated they are useless. I am supposed to write test plans for all of our products quickly.

Half the team seems to be using VS 2013, and the other half of the team seems to be using VS 2010.

This week has been a constant battle of automated builds failing, installers failing to be built properly only to find out after someone hands off an installer that it doesn't even loving work.

But the biggest issue that i simply do not know how to get an integration test environment working correctly. I want something that can be wiped and rebuilt before certain tests. Unfortunately due to our products reliance on requiring a disgusting amount of data (1-2 TB/Day) for any sort of proper testing it makes this seem really impossible.

Ideally the core logic is being unit tested and integration tests exist just to make sure that these systems can talk to one another. Example: I wrote an IRC library a while back. I unit tested all of the core connectivity and message creation/sending/parsing logic (hundreds of tests). Then I wrote 5-10 integration tests to confirm that the library could actually connect to a real IRC server and do some simple IRC operations. The integration tests just validate that I didn't code an implementation of the IRC RFCs that appeared to work when tested in isolation, but had fatal flaws that would prevent it from working when given a real IRC server to talk to.

Also, a "test developer" (i.e. SDET) probably shouldn't be writing test plans. Test plans are in the realm of QA, for manual/automated UI testing.

It's really important to understand the distinction between unit and integration tests. A lot of developers don't. Make sure the folks writing tests do.

I got tired of MVC's string parameters for links in views, so I made an HtmlHelper that uses expressions.

NuGet: https://www.nuget.org/packages/System.Web.Mvc.ExpressionLinks/0.1.1
Github: https://github.com/ckimes89/Mvc-ExpressionLinks

It's super alpha, so it just supports one overload of ActionLink right now, but I plan to add overloads for Url.Action, RedirectToAction, etc. To install it, use install-package System.Web.Mvc.ExpressionLinks.

Here's what you can do with it. Given a controller method that looks like:

C# code:

public class HomeController : Controller
{
     public ActionResult MyMethod(int id, string search)
    {
        return View("Index");
    }
}

You might normally use something like this to make a link in Razor:

C# code:

@Html.ActionLink("My Link", "MyMethod", "Home", new { id = 1, search = "butts" }, null) // have to use null htmlAttributes here because of weird ActionLink overloads

But that sucks. The controller and action names are just strings, so unless your refactoring tool is MVC-string aware you can easily screw things up. The same goes for the parameters since they're just an anonymous object, so changing a parameter name in the action method signature will break things silently.

But instead, using my library:

C# code:

@(Html.ActionLink<HomeController>("My Link", c => c.MyMethod(1, "butts")))

Now, refactoring tools will automatically pick up the usage of MyMethod, renaming parameters in the method signature doesn't cause you headaches, and you don't have to pass in null to the weird ActionLink overload when specifying a controller.

What do you guys think? Would anyone else use this?

I'm not trying to rain on your parade -- this is awesome stuff -- but IIRC the MvcContrib and their FluentHtml bits had this stuff integrated back in the MVC1 days. Now, I'm not sure if that library kept up with MVC because most of what it did got subsumed into the framework. Except for this sort of strongly typed stuff.

FWIW one of the issues with this was it was very expensive at scale but this probably matters less in the modern world of javascript rendered pages.

If I remember right, MvcContrib supported something like this through use of T4MVC which was great in concept but incredibly clunky when you tried to use it in your workflow.

That might have been the case in some later versions of scaffolding. FluentHtml definitely had this as a dynamic, reflective implementation early on until it moved into the Mvc Futures project and died, we were using it before T4 was released . . .

FWIW one of the issues with this was it was very expensive at scale but this probably matters less in the modern world of javascript rendered pages.

I found a bunch of libraries that do something like this for getting the action names, but in my limited search I didn't see anything that extracted the parameter names/values from the expression. It really wasn't much code to implement this, so I would be more surprised if something didn't already exist doing the same thing than if it did.

Regarding performance, I have some ideas about caching the results after parsing the expression. I'd have to profile it, but my guess is the dynamic compilation of LambdaExpressions is the most expensive part and I'm pretty sure that can be done once per expression. I'd have to play with it to know for sure.

I'm glad to hear all the positive responses - I really didn't expect that much. I'll put some effort in to support the rest of the ActionLink overloads, UrlHelper, etc. so that it's more than just a proof of concept.

EDIT: Alright, I added support for Html.Action, Html.RenderAction, and Url.Action. That should be enough to start being useful with it in views. Other things to do would be Html.BeginForm, RedirectToAction in controllers, and whatever else you guys can think of.

Calidus: Oct 31, 2011; Stand back I'm going to try science!

I have a MVC webpage which is used to add items to an order. Think of it like a stupid version of those design your own car webpages every manufacture has now. It has 3 sections, the first section is html form with some inputs used to select and add an single item to the order. The second section is a preview image rendered by the server based on uses current order. The third section is a second html form which is used to remove a previously added part from the order. This is clunky as hell with two different html forms being posted.

I am thinking I have a few ways I think I could make this better:

I could change the page to use MVCs Ajax partial postbacks and just refresh the sections that need refreshed
I could also try and use a single form with multiple submit buttons
I also use Json results, JS and Ajax to update each individual parts of my model and my complex session variable.

Turns out the way to do it to use explicit dependencies in your nuspec - rather than relying on nuget pack to include the dependencies you've got in packages.config. You then configure their version as half-open intervals, like this:
Version="(1.0.0,2.0.0]"
That'll match, say, 2.0.0-rc1 as well as 2.0.0, and it doesn't prevent you from giving your own package a stable version.

C# code:

<asp:TextBox ID="tbStartDate" runat="server" Width="100" />
	<asp:Panel ID="pStartDate" runat="server" CssClass="PopupControl">
	<asp:Calendar ID="cStartDate" runat="server" Width="160px" OnSelectionChanged="cStartDate_SelectionChanged" SkinID="Common_SmallCalendar" />
</asp:Panel>
<cc1:PopupControlExtender ID="pceStartDate" runat="server" TargetControlID="tbStartDate" PopupControlID="pStartDate" Position="Bottom" />

So I have this textbox that displays whatever date is chosen in this calendar control, and now I'm trying to clear whatever text is shown after a postback.

I've tried

code:

tbStartDate.Text = "";
cStartDate.SelectedDates.Clear();
tbStartDate.Value = (there's actually no Value attribute so I can't modify this)

And none of these things work. I've also across https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.calendar.visibledate(v=vs.110).aspx but as far as I know I can't set a DateTime object to be empty, so I'm a loss.

How can I clear the values from this textbox?

EssOEss: Oct 23, 2006; 128-bit approved

You can definitely clear a textbox by setting its .Text to empty. Are you doing it in a sane place? Is there really a postback and is it a full postback updating the whole page, not just some irrelevant part? Are you using any fancy AJAX partial update panels? Oh, it uses PopupControlExtender, so I assume there is some AJAX funny business going on. No idea about how this particular control works, so perhaps there are some nonobvious interactions.

I just figured it out. I had to call UpdatePanel.update(). I was setting the values but there was no actual event triggered to cause the UpdatePanel to refresh.

Ok, so I have one of those trivial things that WPF is being stupid about.

I was thinking about creating a base window class and google quickly squashed that idea. So now, I want to take a simple closing event trigger and apply it across all windows (not user controls) because I have an inherited closing command in my viewmodelbase to handle some cleanup. Copy pasting the xaml is ridiculously tedious and if I forget it in one window, I don't get proper clean up of resources. :emo:

No one really answered you but I would go with a SPA (Single Page App) approach. I think that's the kind of UI that users are expecting today. Post backs work best as a work flow (view -> edit -> view update) but this sounds like a very iterative approach on this page. If you are able I would go with a more traditional SPA approach of using DOM manipulation on the front end and sending JSON to the server. The Ajax partial stuff doesn't seem to be in vogue at Microsoft so could be dropped in a version or two (pure speculation).

                var closeCommand = (ICommand)vm.CloseCommand;

WPF databinding is fundamentally a runtime operation - trying to set it up at compile time is going to result in some hack or another. (There might be some way to do it with F#'s statically resolved type parameters, if you're into that.)

e: I assumed that you don't specifically need a trigger for some other reason.

That will probably work! So I guess I am accomplishing my original goal. I remembered reading that during design time, it wont run specifics of the base class such as the constructor (or something like that) - since it's events only I don't need Design time compatibility. So thank you for your determination.

I still say it's a pretty big drawback we cannot inherit actual XAML. WinForms this was incredibly easy to do and flexible. I might just create my own VS template and hope I never have to go back and edit all my views because I changed the name of something or a namespace (No, I do not have ReSharper - cant afford it

)

Oh man, I remembered this from way back and I had to google a little but, I think I found the solution. I simply remembered that it was configurable options of the OpenFileDialog control and this person seems to have documented them:

Apologies if it doesn't work the way you intended.

You're my savior man. Thanks!
