238 Microsoft Visual Studio 2010: A Beginner’s Guide
In Figure 8-14, the CustomerID is being changed to a ComboBox because it makes
more sense to give the user the option of selecting a customer from a list for a new order,
rather than typing in an ID number. Also, the object defaults to a Grid control, but in this
first example, we only want to add a new order, meaning that the control type should be
changed to Detail. To create a new order form with controls bound to order data, select the
Order object in the Data Sources window and drag and drop the order onto the Designer
of the NewOrder window. Figure 8-15 shows this new window.
Figure 8-15 shows how VS added a Grid layout with two columns and a row for each
field in the Order table. As explained, the CustomerID is a ComboBox and the OrderDate
is a calendar. VS was smart enough to put spaces between the words in the labels, too.
VS didn’t put the Save button on the screen, which is something you would need to do
to save the data. In addition to adding controls to the Designer,
VS added the following
CollectionViewSource control to the NewOrder window’s XAML:
<Window.Resources>
<CollectionViewSource x:Key="orderViewSource"
d:DesignSource="{d:DesignInstance my:Order, CreateList=True}" />
</Window.Resources>
