StyleSelector Class


Provides a way to apply styles based on custom logic.

Namespace:   System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)


public class StyleSelector


Initializes a new instance of a StyleSelector.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodSelectStyle(Object, DependencyObject)

When overridden in a derived class, returns a Style based on custom logic.


Returns a string that represents the current object.(Inherited from Object.)

To create a StyleSelector that applies a style based on custom logic, create a subclass of the StyleSelector class and implement the SelectStyle method.

The following example shows how to define a StyleSelector that defines a Style for a row. This example defines the Background color according to the row index.

The following example shows how to define a ResourceKey for the StyleSelector. The namespc prefix maps to a CLR namespace and the corresponding assembly where the StyleSelector is defined. For more information, see XAML Namespaces and Namespace Mapping for WPF XAML.

The following example shows how to set the ItemContainerStyleSelector property of a ListView to this StyleSelector resource.

For an example of how to create a selector to choose a defined style resource, see the implementation of DataTemplateSelector.SelectTemplate, which allows you to use custom logic to select a DataTemplate, based on a similar concept.
