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 property value. To generate groups based on a property, set the PropertyName property. To change the value that is eventually used for grouping before the groups are generated, use the Converter property to supply a value converter. For example, you might 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 can return a collection, which indicates the items can appear in more than one group.
You can also use the StringComparison property to define how string comparison should occur.
