Fixing the default Windows 8 XAML ItemContainerStyle

One of the things I love about the look of Windows 8 is the little touches of feedback as you navigate around. For example, here is the Messaging icon on the Start screen:

Messaging

If you hover over it on a mouse-based system, you get a little extra border to hint that you can click on it:

Messaging-2

and if you select the icon, you get a different border with an earmarked tick:

Messaging-3

Sweet! So what happens if you try to use this in your own app? Here are the screenshots of a button using the Standard500x130Template in a GridView:

Button

Button-2

Button-3

Now, I don’t consider myself to be a designer but these look pretty ugly to me! If you look at the Standard500x130Template, though, it doesn’t really hint at how it can be made prettier to get it to look more like the Messaging button.

The solution lies with ItemContainerStyle. This is a block of XAML that you can reference from, say, a GridView and it defines what an item is going to look like when it goes through different visual states. The first thing you have to do is use Blend to capture a copy of the default definition by using these steps:

  • Start a new project of type XAML (Windows Store). Select Grid App (XAML).
  • Blend should, by default, open GroupedItemsPage.xaml. If it doesn’t, open it.
  • On the Objects and Timeline pane, open up Grid so that you can see the items defined in the Grid.
  • Right-click on itemGridView and select Edit Additional Templates > Edit Generated Item Container > Edit a Copy:

EditAdditionalTemplate

  • In the window that appears (below), accept the defaults and click on OK:

CreateStyleResource

  • Switch Blend to code view and you should find a style has been added called GridViewItemStyle1. You can copy & paste this either into a central style XAML file for your project or, if only needed on a single page, directly into the Resources section of that page’s XAML.

(If you are struggling with the above steps, you can find the original XAML at the end of this post)

I’ve already mentioned that I’m not a designer, so I don’t pretend to fully understand VisualState or StoryBoard but I’ll work through some of the key elements as I understand them and explain how the rendering of the items works.

Let’s start with what happens when you position the pointer over an item. We’ve seen from the screenshots that a big grey rectangle appears. This happens because the VisualState PointerOver contains the following line:


<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="PointerOverBorder"/>

If you look further down the XAML, you will see that this is a rectangle with a fill colour of ListViewItemPointerOverBackgroundThemeBrush. What the above animation does is switch the opacity so that it becomes visible.

So why is it a big grey rectangle and not a nice border like with the Messaging icon? The answer lies with another rectangle which, by default, is only shown when the item is selected! This is the SelectionBackground rectangle and it is filled with ListViewItemSelectedBackgroundThemeBrush. I’ll come back to this in a minute.

Now, let’s look in more detail at what happens when the item is selected. This is another VisualState called, sensibly enough, Selected. This changes the opacity of SelectionBackground, SelectedBorder and SelectedCheckMark so that they become visible. We’ve already looked at SelectionBackground, so what about SelectedBorder and SelectedCheckMark?

SelectedBorder is another rectangle that gets drawn around the item with a stroke colour of ListViewItemSelectedBackgroundThemeBrush so that you get a thin, unfilled rectangle.

SelectedCheckMark is a grid consisting of two paths – one drawn with a fill colour of ListViewItemSelectedBackgroundThemeBrush and the other drawn with a fill colour of ListViewItemCheckThemeBrush. The latter is the tick and the former is the corner triangle that is drawn around the tick.

So, all of the pieces of the puzzle are there. Why, then, doesn’t the item get drawn even remotely like the Messaging icon? Let’s look at the Selected visual state again. It causes three items to be displayed but there is a problem with this – the SelectionBackground, as defined in the style, is filled with the same colour as the SelectedBorder and the corner triangle in SelectedCheckMark. That is why the border and triangle don’t show up.

After a bit of thinking about this, I made a couple of changes that actually ended up fixing all of the above problems, so I’ll just share my changes:

  • Change the fill colour of SelectionBackground so that it uses a different colour from ListViewItemSelectedBackgroundThemeBrush. In my case, because my items are being drawn on a white background, I fixed the colour at white … you’ll see why in a minute.
  • Change the opacity of SelectionBackground from 0 to 1 so that it is always visible.

Why make the last change? It turns out that the reason you get a big grey rectangle instead of a nice border hint is because the selection background isn’t visible – remember that I mentioned it only gets switched on when the item is selected? So by forcing it to be visible all of the time, that changes the appearance of that big grey rectangle to a nice border hint.

Here are the screenshots after revising the style:

PointerOver

Selected

Much better!

I don’t know or understand why the default style is defined the way it is, and it may be that the changes I’ve made aren’t the optimal ones but they do seem to get my app to be closer to those released by Microsoft. Once you’ve defined the style, all you need to do is reference it in the GridView or ListView with ItemContainerStyle=”{StaticResource <whatever you called it>}”.

Win8 Development: getting icons

One of the significant improvements from developing for the Windows Phone platform is that Windows 8 supports XAML as an image type, allowing you to provide vector graphics rather than rasterised. This ensures that you get the crispest, cleanest iconography you can have because the OS will scale the images appropriately.

One of the sites that I’ve used in the past is the Noun Project. They have some stunning icons, all of which can be downloaded in SVG format … but how to then get that into XAML?

The simplest method I’ve found so far is Mike Swanson’s free Adobe Illustrator to XAML Export plug-in. Download, copy to the right directory, open the SVG file in AI, choose Export > XAML.

Job done.

Well, almost. You’ve then got to incorporate that into the project as a resource, but that’s for another blog ;-).
