Creating a WP7 app: Listbox items of the same width

I love databound listboxes in WP7. I do. I really do. However, every time I come to the part of making a nice template for each item (i.e. shiny ugly orange border, etc.) I fail in having items of equal size. This is usally what I produce:

In WPF, the trick is to set the HorizontalAlignment=”Stretch” property of the Listbox. However, apparently there still some internal bug in the ListBox control, which results in the ListBox simply ingoring that setting.

The solution however is, luckily, provided by Microsoft’s Peter Torr in a reply in here.

<Style TargetType=”ListBoxItem”>

<Setter Property=”HorizontalAlignment” Value=”Stretch” />
<Setter Property=”HorizontalContentAlignment” Value=”Stretch”/>

Using Linq to filter a databound listbox in WPF/Silverlight

In this short tutorial I show how to use Linq in order to filter the items shown in a listbox, which in turn is databound to an ObservableCollection.

Suppose we use the listbox created in the previous tutorial where we show the age and name of each user in the collection. All our databinding code-remains the same as before. What we have to add is a new collection in between our original source and the listbox. The in between collection is our Linq-query result. Each time we wish to change our filter, we change the query. Read more of this post
