Public Class PropertyGroupDescription
	Inherits GroupDescription


Initializes a new instance of the PropertyGroupDescription class.


Initializes a new instance of the PropertyGroupDescription class with the specified property name.

System_CAPS_pubmethodPropertyGroupDescription(String, IValueConverter)

Initializes a new instance of the PropertyGroupDescription class with the specified property name and converter.

System_CAPS_pubmethodPropertyGroupDescription(String, IValueConverter, StringComparison)

Initializes a new instance of the PropertyGroupDescription class with the specified parameters.


Gets or sets a converter to apply to the property value or the item to produce the final value that is used to determine which group(s) an item belongs to.


Gets the collection of names that are used to initialize a group with a set of subgroups with the given names.(Inherited from GroupDescription.)


Gets or sets the name of the property that is used to determine which group(s) an item belongs to.


Gets or sets a StringComparison value that specifies the comparison between the value of an item (as determined by PropertyName and Converter) and the name of a group.


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.)

System_CAPS_pubmethodGroupNameFromItem(Object, Int32, CultureInfo)

Returns the group name(s) for the given item. (Overrides GroupDescription.GroupNameFromItem(Object, Int32, CultureInfo).)


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

System_CAPS_pubmethodNamesMatch(Object, Object)

Returns a value that indicates whether the group name and the item name match so that the item belongs to the group.(Overrides GroupDescription.NamesMatch(Object, Object).)


Raises the PropertyChanged event.(Inherited from GroupDescription.)


Returns whether serialization processes should serialize the effective value of the GroupNames property on instances of this class.(Inherited from GroupDescription.)

Views support the functionality of grouping, which allows the user to partition the collection in the collection view into logical groups. The groups can be explicit, where the user supplies a list of groups, or implicit, where the groups are generated dynamically depending on the data.

PropertyGroupDescription allows you to create implicit groups based on a PropertyName. If you simply want to group by a property you can set the PropertyName property. If you want to change the value that is eventually used for group you can use the Converter property to supply a value converter. For example, you may want to group items based on the first letter of a name. If the PropertyName property is not set, the item itself is passed to the value converter. The converter may return a collection, which indicates the items can appear in more than one group.

You can also define how string comparison should take place using the StringComparison property.
