To apply a style to a control, you create a resource binding between a control's Styleproperty and a Style resource by using a markup extension-an expression enclosed in curly braces ({}) of the form {ResourceType ResourceKey}. There are two types of resources. Static resources are applied at initialization time only. Dynamic resources are applied every time the resource is modified by the app. Because styles normally change during runtime, they are usually used as dynamic resources.

Which of the following statements is false?

A data binding is a pointer to data that's represented by a DataSource object. You can create bindings to a broad range of data types, including objects, collections, data in XML documents,

data in databases and LINQ query results. Data bindings can be created declaratively in XAML markup with markup extensions. To declare a data binding, you must specify the data's source. If it's another element in the XAML markup, you use property ElementName; otherwise, you use Source. Many controls have built-in support for data binding, and do not require a separate Binding object. A ListView, for example, has an ItemsSourceproperty that specifies the data source of the ListView's items-when you set ItemsSource to a collection of data, the objects in the collection automatically become the items in the ListView.

You can create bindings to a broad range of data types, including objects, collections, data in XML documents, data in databases and LINQ query results. Data bindings can be created declaratively in XAML markup with markup extensions. To declare a data binding, you must specify the data's source.

Which of the following statements is false?

A data binding is a pointer to data that's represented by a DataSource object. You can create bindings to a broad range of data types, including objects, collections, data in XML documents, data in databases and LINQ query results. Data bindings can be created declaratively in XAML markup with markup extensions. To declare a data binding, you must specify the data's source. If it's another element in the XAML markup, you use property ElementName; otherwise, you use Source. Many controls have built-in support for data binding, and do not require a separate Binding object. A ListView, for example, has an ItemsSource property that specifies the data source of the ListView's items-when you setItemsSource to a collection of data, the objects in the collection automatically become the items in theListView.
