[AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple=false, Inherited=true)] 
public sealed class ContentPropertyAttribute : Attribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple=false, Inherited=true) */ 
public final class ContentPropertyAttribute extends Attribute
AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple=false, Inherited=true) 
public final class ContentPropertyAttribute extends Attribute
 This managed class is not typically used in XAML. 

If the associated property of a ContentPropertyAttribute is not of type string or object, a type converter will be called at runtime. If a type converter cannot be found at runtime, an exception is thrown.

In order to accept more than a single object element as content, the type of the content property must be a collection type.

An example of a class in Windows Presentation Foundation (WPF) that uses the ContentPropertyAttribute is ContentControl, which the Button class inherits from. The property Content on the ContentControl is the content property set by the ContentPropertyAttribute. If a Button is instantiate in XAML, Content of the Button will be set to the element that is between the start and end button tags.

The following example creates a class named Film which is decorated with the ContentPropertyAttribute. The property named Title is set as the content property.

[ContentProperty("Title")]
public class Film
{
    public Film()
    {
    }

    public string Title
    {
        get { return _title; }
        set { _title = value; }
    }

    private string _title;
}
