Silverlight listbox question

I'm using listBox.ItemsSource = e.Result.Persons, which is a collection of persons. The listbox show开发者_JS百科s the actual object names when I would like it to show the first name of each person object. How can I do this?

use Listboxes ItemTemplate. something like this.

<ListBox>
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding FirstName}"/>
</ListBox.ItemTemplate>
</DataTemplate>
</ListBox>

In addition to the method of binding specified by the other response, you could simply bind it as follows:

listBox.ItemsSource = e.Result.Persons.Select(d => new { FirstName });

Or use the dedicated "DisplayMemberPath" property, which do exactly what you want easily without any side effects (nor additional markup):

<ListBox DisplayMemberPath="FirstName" />

For more complicated item representations, use templates (see below).

You can override the ToString() method of the Persons object so that it display the first name of the person.
